RH050R2000FC02 Equivalent & Substitute Parts

Part Overview

The RH050R2000FC02 is a 200 mOhms ±1% 50W wirewound chassis mount resistor manufactured by Vishay Dale. This component is designed for high-power applications requiring precision resistance in compact form factors with aluminum housing and flanged mounting. The part is currently active in production with 692 units in stock. Substitute parts are necessary when the primary part becomes unavailable, when alternative compliance certifications are required, or when inventory constraints necessitate sourcing from equivalent alternatives within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

The RH050R2000FE02 qualifies as a direct substitute for the RH050R2000FC02 based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Resistance value: 200 mOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 50W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 250°C (exact match)
• Composition: Wirewound (exact match)
• Housing and mounting: Aluminum with flanges (exact match)
• Physical dimensions: 1.968" L x 1.140" W, 0.625" height (exact match)
• Lead style: Solder lugs (exact match)
• Package type: Axial, Box (exact match)

Both parts are manufactured by Vishay Dale within the RH series and maintain identical form factor and thermal characteristics.

Engineering Selection Recommendations

The RH050R2000FE02 is a direct electrical and mechanical equivalent to the RH050R2000FC02. Selection between these parts should be based on compliance requirements and availability:

• RH050R2000FC02: Select when RoHS non-compliant components are acceptable and REACH-affected materials are permitted in the application.

• RH050R2000FE02: Select when ROHS3 compliance is required or when REACH-unaffected status is mandated by regulatory or customer specifications. This part also offers higher inventory availability at 1097 units compared to 692 units for the primary part.

Both parts maintain identical electrical performance, thermal characteristics, and physical form factor, ensuring direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can RH050R2000FE02 replace RH050R2000FC02 in existing designs?

A: Yes. The RH050R2000FE02 is electrically and mechanically identical to the RH050R2000FC02. No circuit modifications or layout changes are required for substitution.

Q: What is the primary difference between these two parts?

A: The RH050R2000FE02 is ROHS3 compliant and REACH unaffected, while the RH050R2000FC02 is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Are the physical dimensions and mounting interfaces identical?

A: Yes. Both parts share identical dimensions of 1.968" L x 1.140" W with a maximum seated height of 0.625", flanged mounting features, and solder lug lead style.

Q: Does the temperature coefficient differ between these parts?

A: No. Both parts maintain a temperature coefficient of ±100ppm/°C and operate across the identical temperature range of -55°C to 250°C.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For applications requiring ROHS3 compliance or REACH-unaffected status, specify RH050R2000FE02. For applications without these constraints, either part is suitable based on availability.

Q: Is the 50W power rating maintained in both parts?

A: Yes. Both the RH050R2000FC02 and RH050R2000FE02 are rated for 50W continuous power dissipation with identical thermal performance.
