The YAGEO FMP300JB-52-160K is a 3-watt metal film resistor designed for applications requiring stable performance across extended temperature ranges. With a resistance value of 160kΩ and ±5% tolerance, this through-hole component delivers reliable current limiting and voltage division in moderate power circuits. The ±100ppm/°C temperature coefficient ensures predictable resistance drift from -55℃ to +155℃, making it suitable for environments where ambient conditions vary significantly.
Metal film construction provides lower noise and better long-term stability compared to carbon film alternatives. The 3W power rating allows the FMP300JB-52-160K to handle higher dissipation than standard quarter-watt or half-watt resistors, reducing the need for heatsinking in many designs. The cylindrical through-hole package measures 5mm in diameter by 15.5mm in length, with axial leads that accommodate conventional PCB mounting or point-to-point wiring. This form factor integrates readily into legacy systems, prototyping setups, and production environments where automated through-hole insertion is already established.
Operating across a temperature span from -55℃ to +155℃ positions this resistor for industrial control systems, automotive electronics, and outdoor equipment where thermal excursions occur during normal operation. The 160kΩ resistance value fits common biasing and feedback networks in amplifier stages, filter configurations, and sensor interfaces. At 3 watts, the component can be applied in LED driver circuits, power supply feedback loops, and discharge paths for energy storage elements, provided thermal management aligns with the application's duty cycle and ambient conditions.
YAGEO's metal film resistor technology emphasizes manufacturing consistency and RoHS compliance, supporting global supply chain requirements. The bag-packed format simplifies handling during prototyping and small-batch assembly. Engineers selecting the FMP300JB-52-160K gain a balance of power handling, temperature stability, and dimensional compatibility with existing through-hole footprints, streamlining component substitution and new design integration without significant layout revisions.

YAGEO FMP300JB-52-160K Replacement Guide for 160kΩ 3W Through-Hole Resistor Selection
When a YAGEO FMP300JB-52-160K is unavailable, nearing end-of-stock, or subject to procurement lead-time risk, the replacement cannot be selected by resistance value alone. This part is a 160kΩ, 3W, ±5%, ±100ppm/°C metal film through-hole resistor in a D5 x L15.5mm axial body, typically used where moderate power dissipation, voltage stress, stability, and board-level thermal spacing all influence long-term reliability.
Suitable equivalent or alternative part numbers may include:
- YAGEO FMP300JR-52-160K
- Vishay PR03000201603JAC00
- KOA Speer MOS3CT52R1603J
- Panasonic ERG-3SJ164
- TE Connectivity CFR3J160K
Among these options, YAGEO FMP300JR-52-160K is usually the closest replacement when the electrical construction and body format must remain aligned with the original YAGEO FMP300JB-52-160K. Vishay PR03000201603JAC00 is often a practical cross-brand substitute for a 160kΩ 3W through-hole resistor, provided temperature coefficient, voltage rating, and mechanical fit are verified against the circuit requirements.
The sections below compare these alternatives from an engineering selection perspective, including electrical compatibility, power derating, thermal behavior, mechanical interchangeability, and post-replacement validation methods.
Original Part Reference: YAGEO FMP300JB-52-160K
The YAGEO FMP300JB-52-160K is a metal film resistor designed for through-hole mounting. Its main design position is not low-power signal trimming, but higher-power axial resistor use where 160kΩ resistance, 3W dissipation capability, and moderate stability are required.
Key engineering characteristics of YAGEO FMP300JB-52-160K include:
- Resistance: 160kΩ
- Power rating: 3W
- Tolerance: ±5%
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C to +155°C
- Mounting style: axial through-hole
- Body size: approximately D5 x L15.5mm
- Packaging: bag-packed
- Resistor type: metal film resistor
- Compliance: RoHS
In real applications, this type of resistor may appear in high-voltage dividers, bleeder networks, discharge paths, bias circuits, snubber-related networks, industrial control boards, power supplies, measurement interfaces, and LED or SMPS auxiliary circuits. Because 160kΩ is a relatively high resistance value for a 3W axial resistor, voltage rating and surface creepage often become as relevant as wattage.
For example, a purely theoretical 3W load at 160kΩ corresponds to:
- Current = √(P/R) = √(3W / 160kΩ) ≈ 4.33mA
- Voltage = √(P x R) = √(3W x 160kΩ) ≈ 693V
However, a resistor’s permissible working voltage may be lower than this theoretical value depending on the manufacturer series. Therefore, any FMP300JB-52-160K replacement should be checked not only for 3W power rating, but also for maximum working voltage, overload voltage, coating behavior, lead spacing, and derating curve.

Electrical Selection Logic for a 160kΩ 3W Through-Hole Resistor Equivalent
A reliable FMP300JB-52-160K alternative should be evaluated in the following order.
First, confirm resistance and tolerance. A 160kΩ ±5% resistor can range from 152kΩ to 168kΩ at room temperature. If the resistor is part of a divider or feedback network, this variation must be analyzed together with the other resistor values. For example, replacing only one resistor in a high-voltage divider may shift the divider ratio even if the nominal value is correct.
Second, check power dissipation at worst-case voltage. The power can be calculated as:
- P = V² / R
For a 160kΩ resistor:
- At 200V: P = 0.25W
- At 400V: P = 1.0W
- At 500V: P = 1.56W
- At 600V: P = 2.25W
- At 693V: P ≈ 3.0W
A 3W resistor should not be selected only because calculated dissipation is below 3W. Ambient temperature, copper area, neighboring heat sources, enclosure airflow, and the manufacturer derating curve determine the actual operating margin.
Third, compare maximum working voltage. In high-resistance power resistors, voltage rating can be reached before wattage rating. A 160kΩ 3W resistor may appear thermally acceptable while still exceeding the resistor’s rated continuous working voltage.
Fourth, evaluate TCR impact. The original YAGEO FMP300JB-52-160K specifies ±100ppm/°C. Over a 100°C temperature change, this corresponds to about ±1% resistance change. A replacement with ±250ppm/°C may shift by about ±2.5%, while ±350ppm/°C may shift by about ±3.5%. In a bleeder resistor, this may be acceptable. In a voltage measurement divider, it may not be.
Fifth, check body size and lead geometry. The original D5 x L15.5mm body sets assumptions for creepage distance, airflow exposure, lead bending, and board clearance. A longer or larger replacement may improve thermal behavior but interfere with neighboring components. A smaller body with the same power rating may run hotter in a dense PCB layout.
Practical Validation Methods Using YAGEO FMP300JR-52-160K as the Preferred Example
YAGEO FMP300JR-52-160K is the preferred replacement example because it is closest to YAGEO FMP300JB-52-160K in manufacturer, product family, nominal value, and intended construction. Even so, an engineering replacement should be validated under the actual operating conditions of the circuit.
Verify Circuit or Driver Compatibility with YAGEO FMP300JR-52-160K
For resistor replacement, “driver compatibility” means confirming that the circuit block driving or sensing through the resistor sees the same electrical load after substitution.
Recommended checks:
- Measure the installed resistance before power-up if the resistor is part of a divider or bias network.
- Confirm the circuit current at nominal and maximum operating voltage.
- For an SMPS startup or auxiliary bias path, verify startup time, controller VCC ramp, undervoltage lockout behavior, and steady-state bias current.
- For an LED driver or constant-current circuit, verify that the resistor does not alter dimming reference, current sense scaling, or protection threshold.
- For a discharge resistor, measure capacitor discharge time and confirm it remains within the intended timing window.
- For a high-voltage sensing circuit, verify ADC input voltage, comparator threshold, and divider ratio at minimum and maximum line voltage.
- Because YAGEO FMP300JR-52-160K is expected to be close to the original FMP300JB-52-160K, major functional shifts are unlikely if the suffix difference is packaging-related. The validation still confirms that the installed component and solder process have not introduced damage, wrong value, or layout-related heating.
Evaluate Thermal Performance After Replacing FMP300JB-52-160K with YAGEO FMP300JR-52-160K
Thermal evaluation should be performed at the highest expected steady-state voltage and ambient condition.
Practical method:
- Power the board at maximum normal input voltage.
- Allow the system to reach thermal equilibrium.
- Measure resistor body temperature using a thermocouple attached near the center of the body, or use an infrared camera with emissivity correction.
- Record ambient temperature near the resistor, not only room temperature.
- Compare measured temperature rise with the original FMP300JB-52-160K if a reference board is available.
- Check nearby electrolytic capacitors, optocouplers, plastic connectors, and cable insulation for added heat exposure.
- Repeat the test in the intended enclosure if airflow is restricted.
- For axial 3W resistors, lead length and mounting height affect heat transfer. If the replacement is mounted closer to the PCB than the original, board discoloration and solder joint temperature may increase. If it is raised higher, vibration behavior and lead stress should be considered.
Identify Waveform and Parameter Changes After Replacement
A resistor does not generate a waveform by itself, but replacing a resistor in a power or control circuit can change time constants, voltage slopes, and sensing thresholds.
Measurements to perform:
Startup waveform:
- Check controller VCC, bias node voltage, or gate-drive enable timing if the resistor participates in startup current or auxiliary supply biasing.
Discharge waveform:
- For capacitor bleeder use, measure the voltage decay curve after input power removal. A 160kΩ resistor should produce a predictable RC discharge curve based on the connected capacitance.
Divider output waveform:
- For high-voltage measurement, monitor the low-voltage divider output with a properly rated differential probe. Look for ratio shift, noise pickup, and overshoot during line transients.
Pulse or surge event:
- If the resistor sees repetitive pulses, compare peak voltage, pulse width, and repetition rate with the pulse load graph of the replacement resistor family.
Noise-sensitive node:
- If the resistor is used near an analog input, check noise floor and measurement stability. A same-family YAGEO FMP300JR-52-160K should behave closest to the original, while carbon film alternatives such as TE Connectivity CFR3J160K may show different noise characteristics.
Application Boundaries for FMP300JB-52-160K Alternatives
A 160kΩ 3W through-hole resistor equivalent can be selected confidently when the application is a low-precision power path, such as a bleeder resistor, preload resistor, or discharge element. In these cases, resistance tolerance and TCR usually affect timing or leakage current rather than closed-loop accuracy.
More careful evaluation is needed when YAGEO FMP300JB-52-160K is used in:
- High-voltage divider networks
- AC mains detection circuits
- SMPS startup circuits
- Feedback compensation or bias circuits
- Precision measurement inputs
- Temperature-sensitive analog circuits
- Safety-related discharge functions
- Circuits exposed to surge or repetitive pulse energy
For divider circuits, replacing only one resistor with a different TCR can create ratio drift over temperature. For startup circuits, a slight resistance shift can alter startup delay or minimum startup voltage. For bleeder applications, the replacement must satisfy both discharge time and steady-state heating.
Procurement and Approval Considerations for YAGEO FMP300JB-52-160K Alternatives
From a procurement perspective, the closest replacement is not always the easiest to qualify. Same-family alternatives reduce engineering risk but may not solve long-term supply concerns. Cross-brand alternatives improve sourcing flexibility but require broader validation.
A practical approval path can include:
- Create an approved vendor list with YAGEO FMP300JR-52-160K as the same-family substitute.
- Add Vishay PR03000201603JAC00 as the preferred cross-brand alternative after thermal and voltage verification.
- Use KOA Speer MOS3CT52R1603J or Panasonic ERG-3SJ164 for power-path applications where TCR and long-term drift are acceptable.
- Reserve TE Connectivity CFR3J160K for non-precision circuits where carbon film behavior does not affect performance.
- Document body size, lead diameter, working voltage, overload rating, TCR, derating curve, and compliance status for each approved option.
- For production release, the approved replacement list should state whether each part is a direct drop-in, conditional substitute, or application-limited alternative. This prevents a general-purpose 160kΩ 3W resistor from being used in a precision or high-voltage position without review.
Conclusion: Choosing the Best Replacement for YAGEO FMP300JB-52-160K
For the closest replacement, select YAGEO FMP300JR-52-160K when it is available and the suffix difference is confirmed as packaging or supply format. It offers the most direct path for replacing YAGEO FMP300JB-52-160K with minimal change to electrical behavior, mounting style, and thermal assumptions.
For a cross-brand production alternative, Vishay PR03000201603JAC00 is usually the next practical option. It should be checked for TCR, maximum working voltage, body dimensions, and derating curve before approval.
For non-precision power applications, KOA Speer MOS3CT52R1603J and Panasonic ERG-3SJ164 can be considered when the circuit can tolerate different film construction and temperature drift.
For cost-sensitive, non-precision use, TE Connectivity CFR3J160K may be acceptable only after confirming power rating, voltage rating, and circuit tolerance for carbon film behavior.
A concise decision path is:
- Use YAGEO FMP300JR-52-160K for the closest same-family replacement.
- Use Vishay PR03000201603JAC00 when a qualified cross-brand 160kΩ 3W through-hole resistor equivalent is needed.
- Use KOA Speer MOS3CT52R1603J or Panasonic ERG-3SJ164 for power resistor positions with relaxed precision requirements.
- Use TE Connectivity CFR3J160K only where drift, noise, and construction differences do not affect circuit performance.
Validate the selected replacement through resistance measurement, power calculation, working-voltage review, thermal testing, and waveform checks in the actual circuit.
