HS150 6R8 J Wirewound Chassis Mount Resistor - Equivalent & Substitute Parts

Part Overview

The HS150 6R8 J is a 6.8 Ohms ±5% 150W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is an active product with 790 units in stock. The HS150 6R8 J is designed for high-power applications requiring stable resistance performance in aluminum-housed configurations with flanged mounting features and solder lug terminations. Substitute parts are identified when the primary part is unavailable or when application requirements permit operation at reduced power ratings while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The HS100 6R8 J qualifies as a parametric equivalent to the HS150 6R8 J based on matching electrical specifications: identical resistance value of 6.8 Ohms, tolerance of ±5%, temperature coefficient of ±100ppm/°C, and wirewound composition. Both parts share identical mechanical characteristics: aluminum housing, flanged mounting features, solder lug terminations, and axial box packaging. The primary distinction is the power rating, where the HS100 6R8 J operates at 100W compared to the 150W rating of the HS150 6R8 J. Substitution is valid when circuit design permits operation within the 100W power envelope. Both parts maintain compliance with RoHS standards and are manufactured within the ARCOL HS series.

Parameter Comparison

Engineering Selection Recommendations

The HS100 6R8 J serves as a direct substitute for the HS150 6R8 J when application power dissipation does not exceed 100W. Both parts are active products with confirmed inventory availability. The HS100 6R8 J maintains RoHS compliance and shares identical electrical parameters including resistance, tolerance, and temperature coefficient. The HS100 6R8 J includes pulse withstanding capability as an additional feature. Physical dimensions differ between the two parts: the HS100 6R8 J measures 2.567" L x 1.870" W (65.20mm x 47.50mm) compared to the HS150 6R8 J dimensions of 3.846" L x 1.075" W (97.70mm x 27.30mm), though both maintain the same seated height of 0.949" (24.10mm). Selection between these parts depends solely on power rating requirements and available board space.

Frequently Asked Questions (FAQ)

Q: Can the HS100 6R8 J replace the HS150 6R8 J in all applications?

A: The HS100 6R8 J is electrically equivalent with identical resistance, tolerance, and temperature coefficient. Substitution is valid only when circuit power dissipation remains within the 100W rating. Applications requiring power dissipation above 100W must use the HS150 6R8 J.

Q: What are the physical differences between these parts?

A: The HS100 6R8 J measures 2.567" L x 1.870" W (65.20mm x 47.50mm), while the HS150 6R8 J measures 3.846" L x 1.075" W (97.70mm x 27.30mm). Both parts share identical seated height of 0.949" (24.10mm) and use flanged mounting with solder lug terminations.

Q: Are both parts RoHS compliant?

A: Yes. The HS150 6R8 J is ROHS3 Compliant. The HS100 6R8 J is RoHS Compliant. Both parts meet regulatory requirements for restricted substance compliance.

Q: What is the pulse withstanding feature on the HS100 6R8 J?

A: The HS100 6R8 J includes pulse withstanding capability as a specified feature. This parameter is not listed for the HS150 6R8 J in the provided data.

Q: How do I determine which part to use?

A: Use the HS150 6R8 J for applications requiring 150W power dissipation. Use the HS100 6R8 J when power dissipation does not exceed 100W and board space permits the smaller footprint. Both parts deliver identical electrical performance within their respective power ratings.
