HS100F8RFS3 Equivalent & Substitute Parts Reference

Part Overview

The HS100F8RFS3 is an aluminum-housed, wirewound chassis mount resistor manufactured by Ohmite, part of the ARCOL HS series. This 100-watt, 8-ohm component is rated for ±1% tolerance and features pulse-withstanding capability with solder lug termination. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both HS100F8RFS3 and NHS100 8R F are Active products manufactured by Ohmite within the ARCOL HS series. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation.

HS100F8RFS3 is suitable for applications where this specific part number is designated in design documentation or procurement specifications.

NHS100 8R F serves as a direct parametric equivalent when HS100F8RFS3 availability is constrained. Both parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance (ROHS3, REACH Unaffected).

Both components are suitable for high-power dissipation applications requiring wirewound construction, aluminum housing, and flanged mounting with solder lug termination. The ±1% tolerance and ±100ppm/°C temperature coefficient ensure precision performance in demanding circuit applications.

Frequently Asked Questions (FAQ)

Q: Can NHS100 8R F be used as a direct replacement for HS100F8RFS3?

A: Yes. NHS100 8R F is a parametric equivalent with identical electrical specifications (8 Ohms, ±1%, 100W), identical mechanical configuration (aluminum housing, flanged mounting, solder lugs), and identical physical dimensions (2.567" L x 1.870" W x 0.949" H). Both parts are ROHS3 compliant and REACH unaffected.

Q: Are there any differences in features between these two part numbers?

A: HS100F8RFS3 is specified with pulse-withstanding capability. NHS100 8R F is specified with both non-inductive and pulse-withstanding features. Both parts share the same core electrical and mechanical parameters required for substitution.

Q: What determines whether a part qualifies as a substitute for HS100F8RFS3?

A: Substitution requires exact matching of resistance (8 Ohms), tolerance (±1%), power rating (100W), temperature coefficient (±100ppm/°C), composition (wirewound), housing material (aluminum), mounting configuration (flanges), lead style (solder lugs), physical dimensions, and compliance certifications (ROHS3, REACH unaffected).

Q: Are both parts available in the same packaging?

A: Yes. Both HS100F8RFS3 and NHS100 8R F are supplied in box packaging with identical axial configuration and solder lug termination.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical physical dimensions, mounting features, and lead styles ensure direct interchangeability in chassis mount applications with flanged mounting and solder lug connections.
