Substitute Part Grouping Explanation

Substitution eligibility for the RH5022R00FS03 is determined by strict equivalence in the following critical parameters:

• Resistance value: 22 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 50W (exact match required)
• Composition: Wirewound (exact match required)
• Housing type: Aluminum (exact match required)
• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The substitute part RH05022R00FE02 meets all mandatory equivalence criteria. Variations in temperature coefficient, maximum operating temperature, and physical dimensions are within acceptable ranges for this product category and do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the RH5022R00FS03 and RH05022R00FE02 are Active products with ROHS3 compliance. The substitute part RH05022R00FE02 provides equivalent electrical performance with an improved temperature coefficient (±20ppm/°C versus ±25ppm/°C) and extended maximum operating temperature capability (250°C versus 200°C). Physical dimensions differ slightly; the substitute is marginally wider and taller. Component selection should account for available board space and thermal management requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can RH05022R00FE02 be used as a direct replacement for RH5022R00FS03?

A: Yes. Both parts share identical resistance, tolerance, power rating, composition, housing type, mounting features, and lead style. Electrical performance is equivalent within specified tolerances.

Q: What are the dimensional differences between these parts?

A: The substitute RH05022R00FE02 is 0.297" wider (28.96mm versus 21.40mm) and 0.034" taller (15.87mm versus 15.00mm). Verify available mounting space before selection.

Q: Does the improved temperature coefficient of the substitute affect compatibility?

A: No. The substitute's ±20ppm/°C coefficient is superior to the main part's ±25ppm/°C. This represents improved thermal stability and does not create compatibility issues.

Q: Are both parts RoHS compliant?

A: Yes. Both RH5022R00FS03 and RH05022R00FE02 are ROHS3 Compliant.

Q: What is the operating temperature difference between these parts?

A: The main part operates from -55°C to 200°C. The substitute extends the upper limit to 250°C, providing broader thermal operating range without affecting lower temperature performance.
