WHB75RFE Equivalent & Substitute Parts

Part Overview

The WHB75RFE is a 75 Ohm ±1% 1W axial wirewound through-hole resistor manufactured by Ohmite. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, and package type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WHB75RFE are qualified based on the following criteria:

• Resistance value: 75 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package: Axial through-hole
• Temperature coefficient: ±20ppm/°C
• RoHS compliance: ROHS3 Compliant

Two substitute parts meet these electrical and mechanical requirements: the Ohmite 41F75RE and the Vishay Dale RS01A75R00FE70. Both maintain identical electrical specifications and axial package compatibility with the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—WHB75RFE, 41F75RE, and RS01A75R00FE70—are Active product status components with ROHS3 compliance and REACH Unaffected status. Selection between these parts is determined by physical space constraints and operating temperature requirements.

The WHB75RFE offers the smallest physical footprint at 0.130" diameter × 0.276" length, suitable for compact board layouts. The 41F75RE (Ohmicone® 40 series) provides a mid-range size at 0.126" diameter × 0.437" length. The RS01A75R00FE70 features the smallest diameter at 0.094" but extends to 0.406" in length and includes moisture-resistant construction with an extended operating temperature range of -65°C to 250°C, compared to the WHB75RFE range of -55°C to 150°C.

Frequently Asked Questions (FAQ)

Q: Can the 41F75RE directly replace the WHB75RFE?

A: Yes. Both parts share identical electrical specifications (75 Ohms ±1%, 1W, ±20ppm/°C) and axial package configuration. Physical dimensions differ slightly, with the 41F75RE being longer (0.437" vs 0.276"), requiring verification of available board space.

Q: What is the primary difference between the RS01A75R00FE70 and the WHB75RFE?

A: The RS01A75R00FE70 maintains identical electrical specifications but features moisture-resistant construction and an extended operating temperature range (-65°C to 250°C versus -55°C to 150°C). Physical dimensions are smaller in diameter but longer in length.

Q: Are all three parts suitable for high-temperature applications?

A: The RS01A75R00FE70 supports operation up to 250°C. The WHB75RFE is rated to 150°C. The 41F75RE operating temperature is not specified in available data.

Q: Do physical dimension differences affect circuit performance?

A: Physical dimensions do not affect electrical performance. Differences impact board layout compatibility and thermal dissipation characteristics in confined spaces.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected.
