WHB25RFE Equivalent & Substitute Parts

Part Overview

The WHB25RFE is a 25 Ohm ±1% 1W axial wirewound through-hole resistor manufactured by Ohmite. This component is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific packaging needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WHB25RFE are qualified based on the following criteria:

Direct Electrical Equivalence: Resistance value of 25 Ohms, tolerance of ±1%, and power rating of 1W are mandatory matching parameters.

Mechanical Compatibility: Axial package configuration with 2 terminations ensures physical and electrical interface compatibility with PCB designs specified for the WHB25RFE.

Material Composition: Wirewound construction maintains thermal and frequency response characteristics consistent with the original specification.

Compliance Alignment: RoHS3 compliance and REACH Unaffected status are required for regulatory equivalence.

Temperature Coefficient: ±20ppm/°C specification ensures predictable performance across temperature variations.

The substitute parts identified—WHB25RFET (Ohmite) and RS01A25R00FE70 (Vishay Dale)—meet all mandatory electrical and mechanical parameters. Packaging format differences (Cut Tape versus bulk) and dimensional variations do not affect functional substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

WHB25RFET (Ohmite): This part is the direct Ohmite equivalent to WHB25RFE, differing only in packaging format (Cut Tape versus standard packaging). Electrical and thermal specifications are identical. Selection is appropriate when Cut Tape packaging aligns with assembly processes and inventory availability is prioritized.

RS01A25R00FE70 (Vishay Dale): This manufacturer-recommended substitute provides equivalent electrical performance with extended operating temperature range (-65°C ~ 250°C) and moisture-resistant construction. Physical dimensions differ slightly (0.094" Dia x 0.406" L versus 0.130" Dia x 0.276" L), which may require PCB layout verification for space-constrained applications. Selection is appropriate for applications requiring enhanced temperature performance or moisture resistance.

All three parts maintain Active product status, full RoHS3 compliance, and REACH Unaffected regulatory standing, ensuring long-term supply chain viability and regulatory acceptance.

Frequently Asked Questions (FAQ)

Q: Can WHB25RFET be used as a direct replacement for WHB25RFE?

A: Yes. Both parts are manufactured by Ohmite with identical electrical specifications (25 Ohms ±1%, 1W, ±20ppm/°C). The difference is packaging format only. Functional substitution is complete.

Q: What are the physical dimension differences between these parts?

A: WHB25RFE and WHB25RFET measure 0.130" Dia x 0.276" L. RS01A25R00FE70 measures 0.094" Dia x 0.406" L. Verify PCB layout clearances if space constraints exist.

Q: Does RS01A25R00FE70 have different electrical performance?

A: No. Resistance, tolerance, power rating, and temperature coefficient are identical. RS01A25R00FE70 offers extended operating temperature range (-65°C ~ 250°C versus -55°C ~ 150°C) and moisture-resistant construction as additional features.

Q: Are all three parts RoHS3 compliant?

A: Yes. WHB25RFE, WHB25RFET, and RS01A25R00FE70 are all ROHS3 Compliant and REACH Unaffected.

Q: Which part should I select for new designs?

A: Selection depends on application requirements. For standard applications, WHB25RFE or WHB25RFET are appropriate. For applications requiring extended temperature performance or moisture resistance, RS01A25R00FE70 is suitable. Verify inventory availability and packaging requirements for your assembly process.
