WHBR75FE Equivalent & Substitute Parts

Part Overview

The WHBR75FE is a 750 mOhms ±1% 1W axial wirewound resistor manufactured by Ohmite. This component is designed for through-hole applications requiring precision current-sensing or low-resistance load applications. The part maintains Active product status with 815 units in current inventory. 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

Substitution eligibility for the WHBR75FE is determined by strict equivalence across the following parameters:

• Resistance value: 750 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±90ppm/°C
• Regulatory compliance: ROHS3 Compliant

The RS01AR7500FE70 manufactured by Vishay Dale meets all substitution criteria. Both parts share identical electrical specifications and axial package geometry, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the WHBR75FE and RS01AR7500FE70 are Active products with ROHS3 compliance and REACH Unaffected status, qualifying them for equivalent use in regulated applications. The RS01AR7500FE70 provides an extended operating temperature range (-65°C ~ 250°C versus -55°C ~ 150°C) and includes moisture-resistant construction. Physical dimensions differ; the Vishay Dale part is smaller in diameter but longer in axial length. Component selection should account for available board space and thermal environment requirements.

Frequently Asked Questions (FAQ)

Q: Can RS01AR7500FE70 replace WHBR75FE in all applications?

A: Yes, provided circuit board layout accommodates the different physical dimensions. The RS01AR7500FE70 measures 0.094" diameter by 0.406" length, compared to the WHBR75FE at 0.130" diameter by 0.276" length. Electrical performance is equivalent.

Q: What is the significance of the moisture-resistant feature on the RS01AR7500FE70?

A: Moisture-resistant construction provides enhanced reliability in humid environments. This feature is specified in the Vishay Dale part but not listed for the Ohmite equivalent.

Q: Are both parts suitable for high-temperature applications?

A: The RS01AR7500FE70 operates to 250°C maximum, exceeding the WHBR75FE limit of 150°C. For applications requiring sustained operation above 150°C, the Vishay Dale part is the appropriate selection.

Q: Do packaging differences affect circuit board assembly?

A: Yes. The WHBR75FE ships in standard packaging, while the RS01AR7500FE70 is supplied in Cut Tape format. Assembly equipment compatibility and tape specifications should be verified before procurement.

Q: Are both parts compliant with current regulatory requirements?

A: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic component procurement.
