Equivalent & Substitute Parts for HS150 2R2 J

Part Overview

The HS150 2R2 J is a 150W wirewound chassis mount resistor manufactured by Ohmite with a resistance value of 2.2 Ohms and ±5% tolerance. This component is classified as Active and is RoHS Compliant. The part is housed in an aluminum enclosure with flanged mounting features and solder lug terminations, designed for applications requiring high power dissipation and pulse withstanding capability.

Substitute parts are identified when equivalent electrical parameters (resistance, tolerance, power rating) and mechanical specifications (housing type, mounting features, lead style) align with the original component's functional requirements.

Substitute Part Grouping Explanation

Substitute parts for the HS150 2R2 J are grouped based on the following criteria:

Critical Parameters (Must Match):

Resistance value: 2.2 Ohms
Composition: Wirewound
Housing type: Aluminum
Mounting feature: Flanges
Lead style: Solder Lugs

Allowable Variations:

Power rating: Lower power ratings (75W, 100W) are acceptable for applications with reduced thermal requirements
Tolerance: Tighter tolerance (±1%) is acceptable as a direct substitute
Packaging format: Bulk or Box packaging does not affect electrical or mechanical compatibility

The three identified substitutes maintain the core electrical and mechanical specifications while offering variations in power handling capacity and tolerance specifications.

Engineering Selection Recommendations

HS75 2R2 J (ARCOL): This 75W variant is suitable for applications where thermal dissipation requirements are lower than the original 150W specification. All electrical parameters (resistance, tolerance, temperature coefficient) and mechanical specifications (housing, mounting, lead style) are compatible. This part maintains RoHS Compliance and Active product status.

HS100 2R2 J (ARCOL): This 100W variant provides an intermediate power rating between the 75W and 150W options. It includes pulse withstanding capability matching the original part and maintains all mechanical and electrical compatibility. RoHS Compliance and Active product status are confirmed.

HS150 2R2 F (Ohmite): This part offers identical power rating and resistance value with improved tolerance specification (±1% versus ±5%). It is manufactured by the same original equipment manufacturer and maintains full mechanical compatibility. ROHS3 Compliance and REACH Unaffected status provide enhanced regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can HS75 2R2 J be used as a direct replacement for HS150 2R2 J?

A: The HS75 2R2 J is electrically and mechanically compatible but has a reduced power rating of 75W compared to 150W. It is suitable only for applications where the thermal load does not exceed 75W continuous dissipation.

Q: What is the difference between HS150 2R2 J and HS150 2R2 F?

A: Both parts have identical 150W power ratings and 2.2 Ohm resistance. The primary difference is tolerance specification: HS150 2R2 J has ±5% tolerance while HS150 2R2 F has ±1% tolerance. HS150 2R2 F also carries ROHS3 Compliant status versus RoHS Compliant for the original part.

Q: Are there dimensional differences between these substitute parts?

A: All substitute parts maintain the same height when seated (0.949" / 24.10mm). Length and width dimensions vary based on power rating: HS75 2R2 J measures 1.917" L x 1.075" W, HS100 2R2 J measures 2.567" L x 1.075" W, and both HS150 variants measure 3.846" L x 1.075" W or 1.870" W depending on the specific model.

Q: Do all substitute parts have the same lead style and mounting features?

A: Yes. All substitute parts use solder lugs for termination and flanged mounting features on aluminum housings, ensuring mechanical compatibility with the original HS150 2R2 J installation.

Q: What packaging options are available?

A: The original HS150 2R2 J is supplied in Box packaging. Substitute parts HS75 2R2 J and HS100 2R2 J are available in Bulk packaging, while HS150 2R2 F is available in Bulk packaging. Packaging format does not affect electrical or mechanical performance.
