• Automotive certification (AEC-Q200) is an additional feature, not a requirement

Parameter Comparison

Engineering Selection Recommendations

RR01J12RTB (TE Connectivity Passive Product): Primary selection for applications requiring extended operating temperature range to 235°C. Suitable for high-temperature industrial environments. ROHS3 compliant with REACH unaffected status. Pulse withstanding capability provides enhanced reliability in transient-prone circuits.

FMP100JR-52-12R (YAGEO): Alternative selection for standard industrial temperature range applications (-55°C to 155°C). Flame proof construction provides enhanced safety characteristics. ROHS3 compliant with MSL rating of 1 (Unlimited). Compact physical dimensions (2.40mm diameter) support space-constrained PCB layouts.

PR01000101209JR500 (Vishay Beyschlag/Draloric/BC Components): Qualified substitute for automotive and high-reliability applications requiring AEC-Q200 certification. Fusible feature provides overcurrent protection capability. Temperature coefficient of ±250ppm/°C offers improved stability compared to the main part. ROHS3 compliant with automotive-grade qualification.

All three parts maintain identical electrical specifications (12 Ohms ±5%, 1W metal film) and axial package configuration, ensuring direct functional interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can FMP100JR-52-12R replace RR01J12RTB in high-temperature applications above 155°C?

A: No. The FMP100JR-52-12R operating temperature range is -55°C to 155°C, while the RR01J12RTB operates to 235°C. For applications requiring temperatures above 155°C, the RR01J12RTB is the appropriate selection.

Q: Are the physical dimensions of substitute parts compatible with existing PCB layouts?

A: Physical dimensions vary between parts. RR01J12RTB measures 0.102" diameter x 0.268" length, FMP100JR-52-12R measures 0.094" diameter x 0.248" length, and PR01000101209JR500 measures 0.098" diameter x 0.256" length. All are standard axial resistor dimensions and fit within typical through-hole spacing. Verify PCB hole positioning and component clearance for specific layouts.

Q: What is the difference between flame retardant and flame proof construction?

A: Flame retardant coating (RR01J12RTB, PR01000101209JR500) resists ignition and slows flame propagation. Flame proof construction (FMP100JR-52-12R) provides enhanced fire resistance. Both meet safety standards; selection depends on application-specific safety requirements.

Q: Is the PR01000101209JR500 suitable for non-automotive applications?

A: Yes. The PR01000101209JR500 is qualified for automotive applications (AEC-Q200) but is not restricted to automotive use. The automotive certification represents an additional qualification level and does not limit general industrial application.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8533.21.0090). Compliance requirements are met across all substitutes.

Q: What is the significance of the temperature coefficient specification?

A: Temperature coefficient indicates resistance value change per degree Celsius. RR01J12RTB has ±300ppm/°C, PR01000101209JR500 has ±250ppm/°C, and FMP100JR-52-12R does not specify this parameter. Lower temperature coefficient values indicate greater stability across temperature variations. For precision applications, PR01000101209JR500 offers superior temperature stability.

Q: Can these parts be used interchangeably in pulse withstanding applications?

A: The RR01J12RTB explicitly features pulse withstanding capability. The FMP100JR-52-12R and PR01000101209JR500 do not list this specification. For applications requiring documented pulse withstanding performance, the RR01J12RTB is the specified selection.
