Engineering Selection Recommendations

Selection between RH025300R0FC02, RH025300R0FE02, and TMC025300R0FE02 is determined by regulatory compliance requirements and supply availability.

The RH025300R0FC02 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present regulatory constraints.

The RH025300R0FE02 provides direct series equivalence with ROHS3 compliance and REACH unaffected status, making it the preferred choice for designs requiring updated environmental compliance certifications while maintaining identical electrical and mechanical performance.

The TMC025300R0FE02 represents a parametric equivalent from an alternative series within the Vishay Dale product line, offering ROHS3 compliance with identical functional specifications. This part is suitable for applications where series flexibility is permitted and compliance requirements align with the RH025300R0FE02.

All three parts are active in production and maintain equivalent inventory levels suitable for production deployment.

Frequently Asked Questions (FAQ)

Q: Can RH025300R0FE02 be used as a direct replacement for RH025300R0FC02?

A: Yes. The RH025300R0FE02 maintains identical electrical specifications (300 Ohms ±1%, 25W, ±20ppm/°C, -55°C to 250°C operating range) and mechanical dimensions (1.062" L x 1.080" W, 0.561" height, solder lugs, aluminum housing with flanges). The primary difference is improved RoHS3 compliance and REACH unaffected status.

Q: What is the difference between RH025300R0FE02 and TMC025300R0FE02?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The difference is series designation: RH025300R0FE02 belongs to the RH series, while TMC025300R0FE02 belongs to the TMC series. Both offer ROHS3 compliance. Selection depends on design documentation requirements and series standardization preferences.

Q: Are physical dimensions identical across all three parts?

A: Yes. All three parts share identical dimensions: 1.062" L x 1.080" W (26.97mm x 27.43mm) with maximum seated height of 0.561" (14.25mm). PCB layout and mechanical mounting are fully compatible.

Q: Which part should be selected for new designs?

A: For new designs, RH025300R0FE02 or TMC025300R0FE02 are recommended due to ROHS3 compliance and improved regulatory status. Both parts are active in production with stable inventory levels.

Q: Are lead styles and solder connection methods identical?

A: Yes. All three parts use solder lugs as the lead style, providing identical connection methodology and PCB assembly compatibility.
