HS150 50R F Equivalent & Substitute Parts

Part Overview

The HS150 50R F is a 50 Ohms ±1% 150W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for high-power applications requiring precision resistance with stable thermal performance. The part maintains Active product status with 1141 units in current inventory. Equivalent and substitute parts are identified when applications require alternative power ratings, physical dimensions, or when primary inventory is unavailable while maintaining critical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the HS150 50R F is determined by the following critical parameters that must remain constant across equivalent parts:

• Resistance value: 50 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Wirewound (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Housing Type: Aluminum (exact match required)
• Mounting Feature: Flanges (exact match required)
• Lead Style: Solder Lugs (exact match required)
• Package Type: Axial, Box (exact match required)
• Series: ARCOL HS (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The HS100 50R F qualifies as a parametric equivalent substitute. While the power rating differs (100W versus 150W), all other electrical and mechanical specifications remain identical. This substitution is valid for applications where the 100W power rating meets or exceeds the circuit requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the HS150 50R F and HS100 50R F maintain Active product status with full ROHS3 compliance and REACH unaffected certification. Selection between these parts is determined by power dissipation requirements in the target application. The HS150 50R F provides 150W capacity, while the HS100 50R F provides 100W capacity. The HS100 50R F is suitable for applications where power dissipation does not exceed 100W. The HS150 50R F is required for applications where power dissipation exceeds 100W but does not exceed 150W. Both parts are electrically and mechanically interchangeable within their respective power rating limits, with identical resistance, tolerance, temperature coefficient, and mounting characteristics.

Frequently Asked Questions (FAQ)

Q: Can the HS100 50R F replace the HS150 50R F in all applications?

A: The HS100 50R F can replace the HS150 50R F only in applications where the actual power dissipation does not exceed 100W. If the circuit requires power dissipation between 100W and 150W, the HS150 50R F must be used.

Q: Are the physical dimensions compatible between these parts?

A: The width (1.075") and height (0.949") are identical. The length differs: HS150 50R F is 3.846" while HS100 50R F is 2.566". Both use identical flanged mounting features and solder lug connections, but physical space constraints must be verified before substitution.

Q: Do these parts have identical electrical characteristics?

A: Yes. Both parts have 50 Ohms resistance, ±1% tolerance, ±100ppm/°C temperature coefficient, and wirewound composition. The only difference is power rating capacity.

Q: Are both parts compliant with current regulations?

A: Yes. Both HS150 50R F and HS100 50R F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the basis for substitution between these parts?

A: Substitution is based on matching all critical parameters: resistance value, tolerance, composition, temperature coefficient, housing type, mounting features, lead style, package type, series designation, and compliance certifications. Power rating is the only variable parameter that determines substitution eligibility.
