RH00512R00FC02 Equivalent & Substitute Parts

Part Overview

The RH00512R00FC02 is a 12 Ohms ±1% 7.5W wirewound chassis mount resistor manufactured by Vishay Dale in the RH series. This component is designed for applications requiring precision resistance with high power dissipation capability and thermal stability across extended temperature ranges. The part is currently active in production with 957 units in stock.

Substitute parts become necessary when the primary part number experiences supply constraints, when design requirements mandate specific compliance certifications, or when alternative series options provide equivalent electrical and mechanical performance within the same application parameters.

• Mounting feature: Flanges
• Lead style: Solder Lugs
• Package type: Axial, Box
• Physical dimensions: 0.600" L x 0.646" W (15.24mm x 16.41mm)
• Height - Seated (Max): 0.335" (8.51mm)

All substitute parts listed maintain identical electrical performance and physical form factor, ensuring direct interchangeability in circuit applications without design modification.

Parameter Comparison

Engineering Selection Recommendations

RH00512R00FE02 is a direct manufacturer equivalent within the RH series. This part maintains identical electrical and mechanical specifications to the RH00512R00FC02. The primary distinction is regulatory compliance: RH00512R00FE02 is ROHS3 compliant and REACH unaffected, whereas the primary part is RoHS non-compliant and REACH affected. Selection of RH00512R00FE02 is appropriate for applications subject to RoHS3 or REACH regulatory requirements.

TMC00512R00FE02 is a parametric equivalent from the TMC series. This part delivers identical electrical performance and mechanical form factor. Like RH00512R00FE02, it is ROHS3 compliant. The TMC series represents an alternative product line from Vishay Dale with the highest current inventory availability at 1074 units. Selection of TMC00512R00FE02 is appropriate when supply of the RH series is constrained or when regulatory compliance mandates ROHS3 certification.

All three parts are active products suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can RH00512R00FE02 be used as a direct replacement for RH00512R00FC02?

A: Yes. RH00512R00FE02 is electrically and mechanically identical to RH00512R00FC02. Both parts share the same resistance value, tolerance, power rating, temperature coefficient, operating temperature range, composition, housing type, mounting features, lead style, package type, and physical dimensions. The primary difference is regulatory compliance status.

Q: What is the difference between RH00512R00FE02 and TMC00512R00FE02?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The difference is the product series: RH00512R00FE02 belongs to the RH series, while TMC00512R00FE02 belongs to the TMC series. Both are ROHS3 compliant. TMC00512R00FE02 currently has higher inventory availability.

Q: Why would I choose TMC00512R00FE02 over RH00512R00FE02?

A: Selection between these two parts depends on supply availability and design requirements. TMC00512R00FE02 offers higher current inventory (1074 units versus 989 units). Both parts meet identical electrical and mechanical requirements and ROHS3 compliance. If supply of the RH series is limited, TMC00512R00FE02 provides an alternative from the same manufacturer with equivalent performance.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts—RH00512R00FC02, RH00512R00FE02, and TMC00512R00FE02—are rated for operating temperatures from -55°C to 250°C with a temperature coefficient of ±20ppm/°C. They are suitable for applications requiring thermal stability across this extended temperature range.

Q: What is the significance of RoHS3 compliance?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. RH00512R00FE02 and TMC00512R00FE02 are ROHS3 compliant, while RH00512R00FC02 is RoHS non-compliant. For applications or markets requiring RoHS3 certification, RH00512R00FE02 or TMC00512R00FE02 must be selected.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not have specific regulatory compliance requirements that exclude the primary part. All three parts share identical electrical performance, power rating, temperature characteristics, and physical form factor. No circuit redesign or PCB modification is required for substitution.
