The Vishay Dale CRA06P08375R0JTA is a surface-mount resistor network featuring four isolated 75-ohm resistive elements in a compact 1206 (3216 metric) package format with concave long-side terminals. This component delivers 62.5 milliwatts power dissipation per element with ±5% resistance tolerance, making it suitable for space-constrained circuit designs requiring multiple matched-value resistors in a unified footprint.
Built on the CRA06 series platform, this eight-pin resistor array provides electrical isolation between each of the four resistive elements, enabling independent operation within multi-channel analog signal processing, interface termination, and discrete pull-up or pull-down configurations. The isolated circuit topology eliminates common-node constraints found in bussed or dual-terminator architectures, offering design flexibility across diverse circuit topologies including parallel signal paths, multi-lane data interfaces, and independent voltage divider networks.
The temperature coefficient specification of ±200 parts per million per degree Celsius provides predictable resistance drift characteristics across the operating temperature envelope from -55°C to 155°C. This thermal stability supports precision measurement circuits, sensor interface conditioning, and analog front-end applications where consistent impedance behavior is required throughout environmental temperature variations. The physical dimensions of 3.20mm length by 1.60mm width with a maximum seated height of 0.70mm enable high-density PCB layouts while maintaining compatibility with standard automated assembly processes.
Surface-mount implementation with tape and reel packaging facilitates automated pick-and-place manufacturing workflows, reducing assembly time and component handling compared to discrete resistor placement. The 1206 package size strikes a balance between power handling capability and board space efficiency, making this resistor network applicable in portable instrumentation, industrial control modules, automotive electronics, and telecommunications equipment where board real estate optimization directly impacts system cost and form factor.
The component carries RoHS3 compliance and maintains Moisture Sensitivity Level 1 classification, requiring no special precautions for storage or handling prior to reflow soldering. Though designated as obsolete by the manufacturer, existing inventory of 796 pieces remains available for production continuity, legacy design support, and replacement requirements. Engineers should evaluate direct cross-reference alternatives including TC164-JR-0775RL, EXB-V8V750JV, and CAT16-750J4LF when planning new designs or managing product lifecycle transitions, ensuring dimensional compatibility and electrical parameter equivalence across substitute components.
When a resistor array becomes obsolete or faces supply chain constraints, design teams must identify functionally equivalent alternatives without compromising circuit performance. The Vishay Dale CRA06P08375R0JTA represents a 75-ohm, four-element isolated resistor network in 1206 footprint, commonly deployed in signal termination, voltage division, and pull-up/pull-down networks. With this component now marked obsolete, engineers require validated alternatives that maintain electrical compatibility while preserving board layout integrity.
Direct substitutes for the CRA06P08375R0JTA include Yageo TC164-JR-0775RL, Panasonic EXB-V8V750JV, and Bourns CAT16-750J4LF. Each alternative maintains the 75-ohm resistance value, ±5% tolerance, and isolated circuit topology while offering comparable thermal and electrical performance within the same 1206 package format.
CRA06P08375R0JTA (1)
Original Component Characteristics and Application Context
The CRA06P08375R0JTA features four independent 75-ohm resistors with isolated circuit architecture, meaning no common terminal connection exists between elements. This topology proves necessary in applications requiring electrical isolation between termination points, such as multi-channel differential pair termination in high-speed digital interfaces or independent current-limiting paths in LED driver circuits.
Key electrical parameters include 62.5mW power dissipation per element and ±200ppm/°C temperature coefficient. The power rating supports moderate current levels—approximately 31mA continuous per element at rated power—while the temperature coefficient indicates resistance drift of 0.02% per degree Celsius, acceptable for most non-precision applications. The -55°C to 155°C operating range covers standard commercial and industrial temperature grades.
The concave long-side terminal configuration provides mechanical advantages during reflow soldering by promoting self-alignment through surface tension, reducing tombstoning risk compared to flat termination designs. The 1206 footprint (3.20mm × 1.60mm × 0.70mm) balances density requirements with manual rework accessibility.
Yageo TC164-JR-0775RL as Primary Alternative
The TC164-JR-0775RL maintains identical electrical specifications: 75-ohm resistance across four isolated elements, ±5% tolerance, and ±200ppm/°C temperature coefficient. Power rating matches at 62.5mW per element, ensuring thermal design margins remain unchanged. The component shares the same 1206 footprint dimensions and long-side terminal configuration, allowing direct pad-compatible substitution without board redesign.
Manufacturing differences exist in internal construction methods. Yageo employs thick-film resistive paste deposition on ceramic substrate, similar to Vishay Dale's approach but with proprietary material formulations. These variations typically affect long-term stability and moisture resistance rather than immediate electrical performance. The TC164 series carries MSL-1 moisture sensitivity rating, matching the original component's unlimited floor life specification.
Thermal performance exhibits negligible difference under typical operating conditions. With identical power ratings and similar ceramic substrate thermal conductivity, junction-to-ambient thermal resistance falls within 5% variance. In applications operating below 50% rated power—common for termination networks—thermal behavior remains indistinguishable between the two components.
Supply chain positioning differs significantly. The TC164 series remains in active production with broader distribution channels, offering improved availability compared to the obsolete CRA06 series. Lead times typically range from stock to six weeks, whereas the original component faces allocation constraints and potential long-term discontinuation of remaining inventory.
Panasonic EXB-V8V750JV with Enhanced Temperature Coefficient
The EXB-V8V750JV provides identical resistance and tolerance specifications but incorporates a tighter ±100ppm/°C temperature coefficient—half that of the original component. This improvement enhances stability in thermally variable environments, such as automotive underhood applications or outdoor industrial equipment subject to wide ambient temperature swings.
The improved temperature coefficient translates to reduced resistance drift over the operating range. Across the full -55°C to 155°C span, maximum drift decreases from ±4.2% (original) to ±2.1% (EXB-V8V). In precision applications where total tolerance budget includes both initial tolerance and thermal drift, this enhancement provides additional margin for other error sources.
Package dimensions nominally match the 1206 standard, though Panasonic specifies slightly tighter dimensional tolerances on terminal width and height. Pad geometry designed to IPC-7351B nominal land pattern specifications accommodates both components without modification. Terminal plating utilizes tin over nickel barrier layer, compatible with standard lead-free reflow profiles per IPC/JEDEC J-STD-020.
Power rating remains 62.5mW per element, maintaining thermal design equivalence. Internal construction employs thin-film deposition rather than thick-film printing, contributing to the improved temperature coefficient. Thin-film technology typically offers better long-term stability and lower current noise, though these advantages manifest primarily in high-precision analog applications rather than standard digital termination.
The EXB-V8V series carries automotive qualification (AEC-Q200) in certain ordering codes, though the specific -V750JV suffix represents the commercial-grade variant. For designs requiring automotive qualification, the -A750JV suffix provides identical specifications with additional reliability screening.
Bourns CAT16-750J4LF for Cost-Sensitive Applications
The CAT16-750J4LF offers matching electrical specifications at a lower cost point, making it suitable for high-volume consumer electronics where component cost directly impacts product competitiveness. Resistance, tolerance, and power ratings align with the original component, while the ±200ppm/°C temperature coefficient matches standard commercial-grade performance.
Package construction utilizes a convex terminal design rather than the concave profile of the original component. This difference affects reflow self-alignment behavior marginally—convex terminals exhibit slightly higher tombstoning susceptibility in unbalanced thermal environments. For designs using controlled reflow profiles with proper preheat ramps, this distinction rarely manifests as yield loss. However, manual rework operations may require additional attention to heating symmetry.
The CAT16 series employs thick-film ruthenium-based resistive paste, common in cost-optimized resistor networks. Material resistivity stability over time falls within standard commercial specifications but may exhibit slightly higher initial settling compared to premium thick-film or thin-film alternatives. Post-reflow aging effects typically stabilize within 1000 hours at operating temperature, representing negligible drift in most applications.
Voltage coefficient specifications are not explicitly published but fall within typical thick-film performance boundaries of approximately 50ppm/V for voltages below 100V. In low-voltage digital applications (3.3V, 5V logic), voltage coefficient effects remain insignificant compared to tolerance and temperature coefficient contributions.
Availability spans multiple distribution channels with competitive lead times, though stock depth varies regionally. The component maintains active status with no announced obsolescence timeline, supporting long-term design requirements for products with multi-year production lifecycles.
Comparison Summary Across Alternative Components
Direct comparison reveals both commonalities and distinctions across the three alternatives:
- Electrical Characteristics: All three alternatives maintain 75-ohm resistance, ±5% tolerance, and 62.5mW power rating. Temperature coefficients range from ±100ppm/°C (EXB-V8V750JV) to ±200ppm/°C (TC164-JR-0775RL and CAT16-750J4LF), with the Panasonic component offering superior thermal stability.
- Package Compatibility: Footprint dimensions conform to 1206 standard across all options. Terminal geometry varies between concave (TC164), standard (EXB-V8V), and convex (CAT16) profiles, affecting reflow self-alignment and rework handling but not requiring board redesign.
- Manufacturing Technology: Yageo and Bourns employ thick-film construction, while Panasonic utilizes thin-film deposition. Technology choice influences long-term stability, noise characteristics, and temperature coefficient but does not affect immediate functional equivalence for standard applications.
- Cost and Availability: Bourns CAT16 targets cost-sensitive segments with competitive pricing and broad availability. Yageo TC164 occupies mid-tier positioning with strong supply chain presence. Panasonic EXB-V8V commands premium pricing reflecting enhanced specifications and automotive-grade options.
- Qualification Status: Standard commercial-grade variants across all three manufacturers support industrial temperature ranges. Panasonic offers automotive-qualified options within the EXB-V8V series for applications requiring AEC-Q200 compliance.
Practical Validation Methods Using Yageo TC164-JR-0775RL
Validation of the TC164-JR-0775RL as a drop-in replacement requires verification across electrical, thermal, and mechanical domains. Initial electrical characterization confirms resistance values within specified tolerance using four-wire measurement techniques to eliminate lead resistance errors. At room temperature, measured values should fall within 71.25 to 78.75 ohms for ±5% tolerance parts.
Temperature coefficient verification involves controlled temperature cycling from -40°C to +125°C with resistance measurement at 25°C intervals. Calculated temperature coefficient should remain within ±200ppm/°C specification, translating to less than 3% resistance change across the 100°C span. This testing identifies outlier components and validates batch consistency, though production-level sampling may rely on manufacturer certification data rather than 100% testing.
Thermal performance validation under operational load conditions confirms power dissipation capability. Applying rated current (31mA per element at 62.5mW) while monitoring component body temperature via thermocouple or thermal camera verifies adequate heat dissipation. Temperature rise above ambient should not exceed values that would push the component beyond rated operating temperature when combined with maximum ambient specifications.
Soldering process compatibility requires reflow profile monitoring with thermocouples attached to component body and PCB land area. Peak temperature should remain below 260°C for lead-free profiles with time above liquidus (217°C) controlled per IPC/JEDEC J-STD-020 specifications. Post-reflow inspection confirms absence of cracking, delamination, or solder voiding through optical or X-ray examination.
Functional validation within the target circuit verifies performance under actual operating conditions. For termination networks, signal integrity measurements using oscilloscope or time-domain reflectometry confirm proper impedance matching and reflection coefficient. In current-limiting applications, voltage drop measurements under load verify expected behavior. For designs employing multiple resistor arrays, sampling across production lots ensures consistency before full-scale deployment.
Long-term reliability assessment through accelerated aging—typically 1000 hours at maximum operating temperature—identifies potential drift mechanisms. Resistance measurements before and after aging quantify stability, with acceptable drift thresholds defined by application requirements. Most standard applications tolerate 1-2% drift over product lifetime, well within ±5% tolerance margins.
Selection Decision Path
Selection among the three alternatives follows application-specific priorities:
- For designs prioritizing thermal stability or operating across wide temperature ranges, the Panasonic EXB-V8V750JV provides the tightest temperature coefficient at ±100ppm/°C. This choice suits precision analog circuits, automotive applications, or outdoor industrial equipment where ambient temperature variations significantly impact circuit performance. The component's thin-film construction offers additional advantages in low-noise analog environments.
- When supply chain continuity and cost-effectiveness drive decisions, the Yageo TC164-JR-0775RL balances performance, availability, and pricing. Active production status and broad distribution support long-term procurement strategies, while electrical specifications match the original component without compromise. This option fits commercial and industrial designs without specialized thermal or qualification requirements.
- In high-volume, cost-sensitive applications where component pricing directly affects product viability, the Bourns CAT16-750J4LF delivers equivalent electrical performance at competitive cost. The convex terminal design requires attention during reflow process optimization but poses minimal risk with proper thermal management. This selection aligns with consumer electronics, LED lighting, or other price-competitive segments.
All three alternatives maintain electrical and mechanical compatibility with the obsolete CRA06P08375R0JTA, enabling straightforward substitution without circuit redesign or board layout modifications. Selection ultimately depends on thermal requirements, qualification needs, supply chain strategy, and cost targets specific to each application.
