HS150 8R F Equivalent & Substitute Parts

Part Overview

The HS150 8R F is an 8 Ohms ±1% 150W wirewound chassis mount resistor manufactured by Ohmite, part of the ARCOL HS series. This component is designed for high-power applications requiring precision resistance with aluminum housing and flange mounting. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS150 8R F is determined by the following critical parameters:

• Resistance Value: Must be 8 Ohms
• Tolerance: Must be ±1%
• Composition: Must be Wirewound
• Temperature Coefficient: Must be ±100ppm/°C
• Housing Type: Must be Aluminum
• Mounting Feature: Must include Flanges
• Lead Style: Must be Solder Lugs
• Compliance: Must maintain ROHS3 and REACH unaffected status

The HS100 8R F qualifies as a parametric equivalent based on matching all electrical and mechanical specifications. The primary distinction is the power rating differential, which affects thermal performance and physical dimensions but does not alter the fundamental substitution criteria for applications where the lower power rating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the HS150 8R F and HS100 8R F maintain Active product status with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts depends on circuit power dissipation requirements. The HS150 8R F accommodates applications requiring the full 150W thermal capacity, while the HS100 8R F is suitable for circuits operating at or below 100W. Both components share identical electrical characteristics (8 Ohms ±1%, ±100ppm/°C temperature coefficient) and mechanical mounting interfaces (aluminum housing, flange mounting, solder lugs). Dimensional differences reflect the power rating variance, with the HS100 8R F featuring reduced length due to lower thermal mass requirements.

Frequently Asked Questions (FAQ)

Q: Can the HS100 8R F replace the HS150 8R F in all applications?

A: The HS100 8R F is suitable only for applications where circuit power dissipation does not exceed 100W. Applications requiring the full 150W thermal capacity must use the HS150 8R F.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts provide 8 Ohms ±1% resistance with ±100ppm/°C temperature coefficient and wirewound composition.

Q: Do these parts share the same mounting interface?

A: Yes. Both components feature aluminum housing with flange mounting and solder lugs, ensuring mechanical compatibility in identically designed mounting fixtures.

Q: What is the primary dimensional difference?

A: The HS100 8R F has a length of 2.566" (65.20mm) compared to the HS150 8R F at 3.846" (97.70mm). Width and seated height remain identical at 1.075" (27.30mm) and 0.949" (24.10mm) respectively.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the HS150 8R F and HS100 8R F are ROHS3 Compliant and REACH Unaffected, maintaining Active product status.
