The RH050R2500FE02 meets all electrical and mechanical parameters required for direct substitution with the RH050R2500FC02. Both parts are manufactured by Vishay Dale within the RH series and share identical specifications across resistance, tolerance, power rating, thermal characteristics, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The RH050R2500FE02 is a direct electrical and mechanical equivalent to the RH050R2500FC02. Both parts are active products from Vishay Dale with identical performance specifications across all critical parameters: resistance, tolerance, power rating, thermal characteristics, and physical dimensions.

The primary distinction between these parts is regulatory compliance status. The RH050R2500FE02 carries ROHS3 compliance and REACH Unaffected status, whereas the RH050R2500FC02 is RoHS non-compliant and REACH Affected. Selection between these parts should be based on application regulatory requirements and end-market compliance mandates.

Both parts maintain equivalent inventory availability, with the RH050R2500FC02 at 911 units and the RH050R2500FE02 at 855 units in stock.

Frequently Asked Questions (FAQ)

Q: Can RH050R2500FE02 be used as a direct replacement for RH050R2500FC02?

A: Yes. The RH050R2500FE02 meets all electrical and mechanical specifications of the RH050R2500FC02, including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, housing type, mounting configuration, lead style, and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The RH050R2500FE02 differs in regulatory compliance: it is ROHS3 compliant and REACH Unaffected, while the RH050R2500FC02 is RoHS non-compliant and REACH Affected. Selection depends on application compliance requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions of 1.968" L x 1.140" W (49.99mm x 28.96mm) with a maximum seated height of 0.625" (15.87mm). PCB layout and mechanical mounting are interchangeable.

Q: Do both parts have the same thermal performance?

A: Yes. Both parts operate across -55°C ~ 250°C with a temperature coefficient of ±100ppm/°C. Thermal stability and performance characteristics are equivalent.

Q: Which part should I select for new designs?

A: Selection should be based on regulatory compliance requirements for your application. If ROHS3 compliance and REACH Unaffected status are required, use RH050R2500FE02. If legacy compliance status is acceptable, either part is suitable based on availability and supply chain considerations.
