H8562KBZA

The H8562KBZA from TE Connectivity Passive Product is a precision through-hole metal film resistor delivering 562 kOhms resistance with ±0.1% tolerance. This axial leaded component handles 0.25W continuous power dissipation while maintaining tight resistance accuracy across operational temperature ranges from -55°C to 155°C. The metal film construction provides stable electrical characteristics with a temperature coefficient of ±100ppm/°C, suitable for applications requiring long-term resistance stability and minimal drift under thermal cycling.

Belonging to TE Connectivity's Holco/Holsworthy series, this quarter-watt resistor incorporates pulse withstanding capability, allowing it to survive transient voltage events and current surges that would typically damage standard film resistors. The pulse tolerance makes it applicable in measurement circuits, precision voltage dividers, and feedback networks where occasional overvoltage conditions occur. The 0.1% tolerance class positions this component in precision analog signal conditioning, instrumentation amplifier gain setting, and reference voltage generation where fractional resistance errors directly impact system accuracy.

The axial package measures 0.098" diameter by 0.283" length (2.50mm × 7.20mm), providing mechanical compatibility with standard PCB hole patterns and legacy through-hole assembly processes. The two-terminal axial configuration supports both horizontal and vertical mounting orientations, offering layout flexibility in dense circuit boards. Metal film technology delivers lower noise characteristics compared to carbon composition alternatives, making the H8562KBZA suitable for low-noise preamplifier stages and high-impedance sensor interfaces.

The 562 kOhm value finds common usage in operational amplifier feedback networks requiring megohm-range impedances, photodiode transimpedance amplifiers, and high-impedance voltage dividers for analog-to-digital converter reference scaling. The combination of tight tolerance and low temperature coefficient maintains precision across industrial temperature environments without requiring calibration compensation. RoHS3 compliance ensures compatibility with lead-free assembly processes and modern environmental regulations.

Designers working with precision analog circuits, bridge networks, or instrumentation amplifiers often specify resistors with tolerances of 0.1% or better to maintain measurement accuracy and minimize drift over temperature. When the TE Connectivity H8562KBZA becomes unavailable due to lead times, allocation, or obsolescence planning, identifying functionally equivalent alternatives requires careful evaluation of not only basic electrical parameters but also pulse handling capability, temperature coefficient matching, and long-term stability characteristics that directly affect circuit performance.

The H8562KBZA is a 562 kOhm ±0.1% metal film resistor rated at 0.25W with a ±100ppm/°C temperature coefficient and pulse withstanding features, packaged in an axial through-hole format suitable for professional audio equipment, test fixtures, and medical devices where component-level reliability and traceability are non-negotiable. Direct replacements and functional alternatives from manufacturers such as Vishay, Susumu, Bourns, and KOA Speer are available in the market. These include the Vishay Beyschlag MBB02070C5623FCT00 MBB02070C5623FCT00 Vishay Beyschlag/Draloric/BC Components RES 562K OHM 0.6W 1% AXIAL 2000000 , Susumu RG2012N-562-B-T5 RG2012N-562-B-T5 Susumu RES SMD 5.6K OHM 0.1% 1/8W 0805 2000000 , Bourns CR0805-JW-562KLF, KOA Speer MF1/4LCT52R5623F, Yageo MFR-25FBF52-562K MFR-25FBF52-562K YAGEO RES 562K OHM 1% 1/4W AXIAL 3578 , Panasonic ERA-6AEB5623V ERA-6AEB5623V Panasonic Electronic Components RES 562K OHM 0.1% 1/8W 0805 16952 , and Stackpole RNMF14FTC562K.

The H8562KBZA belongs to the Holco/Holsworthy series from TE Connectivity Passive Product, a lineage known for high-stability performance in precision applications. Its 562 kOhm resistance value combined with ±0.1% tolerance places it in a category commonly used for feedback networks in operational amplifier circuits, voltage dividers in ADC reference paths, and current sensing applications where ratio matching and absolute accuracy both matter.

The pulse withstanding feature differentiates this component from standard metal film resistors. Circuits exposed to transient events such as relay switching, motor start currents, or ESD-induced voltage spikes benefit from components that can absorb short-duration overload without parameter shift or catastrophic failure. The ±100ppm/°C temperature coefficient ensures that resistance drift remains within 1% over a 100°C temperature swing, maintaining circuit accuracy across the specified -55°C to 155°C operating range.

Axial through-hole construction provides mechanical robustness and ease of inspection in applications where visual verification and rework are part of the quality assurance process. The 0.098" diameter and 0.283" body length accommodate standard lead spacing for PCB layouts designed around legacy component footprints, a consideration when retrofitting existing designs or maintaining long-lifecycle products.

The Vishay Beyschlag MBB02070C5623FCT00 MBB02070C5623FCT00 Vishay Beyschlag/Draloric/BC Components RES 562K OHM 0.6W 1% AXIAL 2000000 offers a direct match to the H8562KBZA across all critical electrical and mechanical parameters. This metal film resistor delivers 562 kOhm resistance with ±0.1% tolerance, 0.25W power dissipation, and ±100ppm/°C temperature coefficient, maintaining the same axial package dimensions suitable for drop-in replacement without PCB modification.

Vishay's MBB series incorporates pulse load capability inherent to its construction, addressing transient robustness requirements in the same manner as the Holco series. The hermetically sealed resistor element provides moisture resistance and long-term stability, making it suitable for medical instrumentation and aerospace applications where component drift over years of service must remain predictable.

One distinction lies in manufacturing process maturity. Vishay's global supply chain and multiple production sites offer availability advantages during component shortages, while maintaining compliance with ROHS3, REACH, and conflict minerals regulations. Lead finish options and tape-and-reel packaging variants expand integration flexibility for automated assembly lines transitioning from manual placement.

Thermal performance remains equivalent under steady-state conditions, though validation of transient pulse response should confirm energy absorption capacity matches the original design margin. The MBB02070C5623FCT00 MBB02070C5623FCT00 Vishay Beyschlag/Draloric/BC Components RES 562K OHM 0.6W 1% AXIAL 2000000 maintains full electrical specification across the -55°C to 155°C temperature range without derating below 70°C, simplifying thermal analysis in most applications.

The KOA Speer MF1/4LCT52R5623F provides a functional alternative where form factor and electrical specifications align with the H8562KBZA, though with subtle differences in construction that may affect selection in high-reliability contexts. This 562 kOhm ±0.1% metal film resistor operates at 0.25W with a ±100ppm/°C temperature coefficient, matching the core performance envelope required for precision analog signal paths.

KOA Speer's MF series employs a metal film deposition process optimized for manufacturing efficiency, translating to favorable pricing in volume orders without sacrificing fundamental accuracy or stability. This makes it a viable candidate for commercial products where total cost of ownership includes component price, assembly yield, and field failure rates rather than absolute performance margins.

The primary consideration involves pulse handling characteristics. While the MF1/4LCT52R5623F meets standard pulse load requirements per IEC 60115-1 60115-1 TE Connectivity AMP Connectors CONN TERM PIN 20-22AWG CRIMP 43971 , it does not carry an explicit pulse withstanding specification equivalent to the Holco series. Applications where transient energy absorption is incidental rather than a primary design constraint can proceed with this alternative, provided that circuit-level protection such as TVS diodes or RC snubbers address overvoltage events.

Mechanical compatibility is maintained through standard axial lead spacing, though lead wire diameter and tin plating thickness may vary slightly from the H8562KBZA. Solderability testing and pull-strength validation should be part of the qualification process when transitioning production lines, particularly for wave soldering or selective soldering processes where thermal profile differences can affect joint formation.

The Yageo MFR-25FBF52-562K MFR-25FBF52-562K YAGEO RES 562K OHM 1% 1/4W AXIAL 3578 represents a widely distributed alternative with global logistics infrastructure supporting rapid procurement and just-in-time delivery models. This 562 kOhm ±0.1% metal film resistor operates at 0.25W with a ±100ppm/°C temperature coefficient, meeting the fundamental requirements for precision resistor applications where the H8562KBZA was originally specified.

Yageo's market presence across distribution channels provides inventory depth that can mitigate supply chain disruptions, a factor increasingly relevant in strategic component sourcing decisions. The MFR series has established a track record in consumer electronics, industrial controls, and telecommunications equipment, with broad qualification across major OEMs.

Thermal stability and noise performance align with standard metal film technology, though designers should verify that the Yageo part maintains resistance tolerance across the full operating temperature range without additional derating. Some metal film resistors exhibit tighter tolerance at room temperature but approach tolerance limits at temperature extremes, a behavior that can affect precision circuits operating in harsh environments.

Pulse withstanding is not a highlighted feature in the MFR series datasheet, suggesting that applications requiring explicit transient energy absorption should include additional circuit-level validation. For steady-state applications where resistor dissipation remains well below rated power and voltage transients are managed externally, the MFR-25FBF52-562K MFR-25FBF52-562K YAGEO RES 562K OHM 1% 1/4W AXIAL 3578 provides a cost-effective and readily available alternative with acceptable performance margins.

The Bourns CR0805-JW-562KLF offers a surface mount alternative for designs transitioning from through-hole to SMT assembly, or for new projects where board space and automated placement drive component selection. This 562 kOhm ±0.1% thick film chip resistor operates at 0.125W with a ±100ppm/°C temperature coefficient, packaged in a standard 0805 footprint.

Shifting from axial through-hole to SMT construction requires careful evaluation of power dissipation and thermal management. The CR0805-JW-562KLF's 0.125W rating represents half the power capacity of the H8562KBZA, necessitating circuit analysis to confirm that actual resistor dissipation remains within the derated limits. PCB copper area, trace width, and ambient temperature all influence the component's ability to reject heat in surface mount configurations.

Thick film construction, typical of chip resistors, exhibits slightly different noise characteristics and long-term stability compared to metal film technology. For applications where Johnson noise or 1/f noise contributions are significant relative to signal levels, measurement of noise spectral density should confirm acceptable performance. Precision voltage references, photodiode transimpedance amplifiers, and high-gain audio circuits may exhibit measurable differences.

Mechanical stress sensitivity increases in surface mount packages, particularly during thermal cycling and board flexure. The Bourns CR series incorporates stress-relief termination design, but applications exposed to vibration, shock, or frequent thermal excursions should include accelerated life testing to validate reliability. The absence of leads eliminates lead inductance, a benefit in RF or high-frequency signal paths where parasitic effects degrade performance.

The Panasonic ERA-6AEB5623V ERA-6AEB5623V Panasonic Electronic Components RES 562K OHM 0.1% 1/8W 0805 16952 addresses applications requiring AEC-Q200 qualification and extended temperature range performance beyond standard industrial ratings. This 562 kOhm ±0.1% thin film chip resistor operates at 0.125W with a ±100ppm/°C temperature coefficient, packaged in a 0805 format with automotive-grade manufacturing controls.

Thin film resistors inherently provide superior noise performance and long-term stability compared to thick film technology, making the ERA series suitable for precision measurement systems and sensor interface circuits where component aging must remain predictable over 15-year service life requirements. Panasonic's tight process control ensures lot-to-lot consistency, reducing the need for circuit trimming or calibration during production.

The transition from 0.25W axial to 0.125W surface mount again requires thermal analysis, though automotive applications typically incorporate robust thermal management due to under-hood temperature environments. PCB design must allocate sufficient copper pour and thermal vias to maintain junction temperature below maximum ratings during worst-case ambient and loading conditions.

Panasonic's automotive qualification includes humidity resistance testing, high-temperature operating life, and solder reflow profiling that exceeds commercial-grade requirements. For medical devices, aerospace systems, or industrial equipment targeting extended operational lifetimes, the additional quality assurance provides risk mitigation even when formal automotive certification is not mandated by the end application.

The Stackpole RNMF14FTC562K serves as a general-purpose alternative with balanced electrical performance and commercial availability. This 562 kOhm ±1% metal film resistor operates at 0.25W with a ±100ppm/°C temperature coefficient, matching the power rating and temperature coefficient of the H8562KBZA while accepting a tolerance compromise.

The ±1% tolerance represents a ten-fold relaxation from the H8562KBZA's ±0.1% specification, limiting applicability to circuits where absolute resistance accuracy can be absorbed through calibration, trimming, or design margin. Voltage dividers with subsequent ADC gain adjustment, bias networks with wide component tolerance stackup, and non-critical filtering applications may accommodate this tolerance without performance degradation.

Cost advantages become significant when tolerance relaxation is acceptable, as ±1% metal film resistors occupy a high-volume commodity market segment with aggressive pricing and broad second-source options. Bill-of-materials optimization efforts often identify opportunities to substitute tighter-tolerance components with looser specifications where circuit analysis confirms adequate margin.

Temperature coefficient and power rating alignment with the original specification maintain thermal stability and power handling capability, allowing the RNMF14FTC562K to function in environments and loading conditions equivalent to the H8562KBZA design intent. Pulse withstanding is not explicitly characterized, positioning this alternative for steady-state applications without transient stress requirements.

Direct comparison across electrical, mechanical, and availability parameters clarifies the selection decision space. The Vishay Beyschlag MBB02070C5623FCT00 MBB02070C5623FCT00 Vishay Beyschlag/Draloric/BC Components RES 562K OHM 0.6W 1% AXIAL 2000000 provides the closest form-fit-function match with equivalent tolerance, power rating, temperature coefficient, and pulse handling, making it the primary drop-in replacement for existing designs without qualification burden.

The KOA Speer MF1/4LCT52R5623F and Yageo MFR-25FBF52-562K MFR-25FBF52-562K YAGEO RES 562K OHM 1% 1/4W AXIAL 3578 offer cost-optimized alternatives with matching electrical specifications but reduced emphasis on pulse withstanding, suitable for applications where transient protection is managed at circuit level rather than component level. Supply chain diversity between these sources provides risk mitigation against single-source dependencies.

Surface mount alternatives including the Bourns CR0805-JW-562KLF and Panasonic ERA-6AEB5623V ERA-6AEB5623V Panasonic Electronic Components RES 562K OHM 0.1% 1/8W 0805 16952 enable PCB design modernization and automated assembly integration, accepting a power rating reduction to 0.125W that requires thermal validation. The Panasonic part adds automotive qualification value for high-reliability applications, while the Bourns component addresses commercial and industrial requirements.

The Stackpole RNMF14FTC562K trades tolerance precision for cost savings, applicable where circuit design margins accommodate ±1% resistance variation. Power rating and temperature coefficient alignment maintain compatibility for thermal and stability-sensitive designs, though absolute accuracy requirements must be verified against the relaxed tolerance specification.

Pulse withstanding capability, explicitly characterized in the H8562KBZA, appears as a distinguishing feature requiring validation in alternatives. The Vishay MBB series maintains this characteristic through hermetic construction, while other alternatives rely on standard metal film robustness without specific pulse energy ratings. Applications with known transient stress profiles should include pulse testing during qualification.

Validating a replacement resistor in a precision analog circuit requires verification beyond datasheet comparison. Using the Vishay MBB02070C5623FCT00 MBB02070C5623FCT00 Vishay Beyschlag/Draloric/BC Components RES 562K OHM 0.6W 1% AXIAL 2000000 as a drop-in alternative to the H8562KBZA, bench-level testing should first confirm resistance accuracy using a precision multimeter or bridge measurement system with four-wire Kelvin connections to eliminate lead resistance errors. At room temperature, measured resistance should fall within the ±0.1% tolerance band, typically yielding values between 561.44 kOhm and 562.56 kOhm.

Temperature coefficient validation involves controlled thermal cycling from -55°C to 155°C while monitoring resistance change. A temperature chamber with stable setpoint control and a data acquisition system capable of recording resistance at multiple temperature steps reveals whether drift remains within the ±100ppm/°C specification. Over a 100°C temperature swing, total resistance change should not exceed 5.62 kOhm, maintaining circuit accuracy in applications spanning automotive underhood environments or outdoor telecom installations.

Thermal performance under load requires mounting the component on a test PCB with copper pad geometry representative of the final application. Applying power incrementally while measuring case temperature with thermocouples or infrared imaging confirms that thermal resistance from junction to ambient allows the resistor to dissipate rated power without exceeding maximum operating temperature. For the Vishay part, junction temperature should remain below 155°C when dissipating 0.25W in a 70°C ambient with standard PCB thermal relief.

Pulse handling verification exposes the component to transient waveforms representative of circuit stress conditions. Applying repetitive pulses with rise times, durations, and energy levels matching or exceeding expected transients, while monitoring resistance change after each pulse train, confirms that the component maintains specification. Oscilloscope waveform capture of voltage across the resistor during pulse events reveals whether parasitic effects or thermal excursions introduce non-linear behavior. Post-stress resistance measurement and visual inspection for physical damage complete the validation, ensuring the Vishay MBB02070C5623FCT00 MBB02070C5623FCT00 Vishay Beyschlag/Draloric/BC Components RES 562K OHM 0.6W 1% AXIAL 2000000 withstands operational conditions equivalent to the original H8562KBZA design intent.

Selecting among available alternatives begins with classifying the application according to tolerance requirements, transient exposure, and packaging constraints. Circuits requiring ±0.1% absolute accuracy with pulse withstanding capability and through-hole construction should prioritize the Vishay Beyschlag MBB02070C5623FCT00 MBB02070C5623FCT00 Vishay Beyschlag/Draloric/BC Components RES 562K OHM 0.6W 1% AXIAL 2000000 as a qualified drop-in replacement, minimizing validation effort and production disruption.

Applications accepting surface mount construction to enable automated assembly or reduce board footprint should evaluate the Bourns CR0805-JW-562KLF for commercial and industrial products, or the Panasonic ERA-6AEB5623V ERA-6AEB5623V Panasonic Electronic Components RES 562K OHM 0.1% 1/8W 0805 16952 when automotive qualification or thin-film stability benefits justify the additional cost. Both require thermal analysis due to reduced power ratings, and designs with dissipation approaching 0.125W must increase copper area or reduce loading.

Cost-sensitive designs where circuit margins accommodate ±1% tolerance can leverage the Stackpole RNMF14FTC562K, accepting the tolerance trade-off to achieve bill-of-materials savings in volume production. Calibration or trim procedures during manufacturing can compensate for wider component spread, provided the temperature coefficient remains matched to the original specification.

Supply chain resilience favors qualifying multiple sources from the KOA Speer MF1/4LCT52R5623F, Yageo MFR-25FBF52-562K MFR-25FBF52-562K YAGEO RES 562K OHM 1% 1/4W AXIAL 3578 , and Vishay MBB02070C5623FCT00 MBB02070C5623FCT00 Vishay Beyschlag/Draloric/BC Components RES 562K OHM 0.6W 1% AXIAL 2000000 group, enabling flexible procurement strategies during allocation periods. Multi-source qualification distributes risk and provides negotiation leverage, though it increases initial validation workload and inventory complexity.
