HS150 1R F Equivalent & Substitute Parts

Part Overview

The HS150 1R F is a 1 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 aluminum housing and flange mounting. The part is currently active in production with 777 pieces in stock. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits operation at alternative power ratings within the same electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HS150 1R F is determined by strict equivalence in the following electrical and mechanical parameters: resistance value (1 Ohms), tolerance (±1%), composition (wirewound), temperature coefficient (±100ppm/°C), housing material (aluminum), mounting feature (flanges), lead style (solder lugs), and package type (axial, box).

The identified substitute parts maintain these core specifications. The HS150 1R F (ARCOL manufacturer variant) is a parametric equivalent with identical electrical characteristics and physical dimensions. The HS75 1R F is a lower power-rated alternative (75W versus 150W) that maintains all other electrical and mechanical parameters, suitable for applications where the full 150W capacity is not required.

Parameter Comparison

Engineering Selection Recommendations

The HS150 1R F (ARCOL) is a direct parametric equivalent to the Ohmite HS150 1R F, maintaining identical electrical specifications and physical dimensions. Both variants are active products with RoHS compliance and suitable for direct substitution in applications requiring 150W power dissipation at 1 Ohms resistance.

The HS75 1R F is a lower power-rated substitute suitable only for applications where the circuit design permits operation at 75W instead of 150W. This part maintains all electrical parameters (resistance, tolerance, temperature coefficient) and mechanical mounting features. Selection of the HS75 1R F requires verification that the application's power dissipation requirements do not exceed 75W. The HS75 1R F offers a more compact form factor (1.917" length versus 3.846" length) while maintaining the same height and flange mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can the HS75 1R F replace the HS150 1R F in all applications?

A: No. The HS75 1R F is rated for 75W maximum power dissipation, while the HS150 1R F is rated for 150W. Substitution is only valid when the circuit design operates at or below 75W. Exceeding this power rating will result in component failure.

Q: Are the HS150 1R F (Ohmite) and HS150 1R F (ARCOL) interchangeable?

A: Yes. Both parts are parametric equivalents with identical resistance (1 Ohms), tolerance (±1%), power rating (150W), temperature coefficient (±100ppm/°C), and mounting specifications. Physical dimensions are identical. Both are active products with appropriate RoHS compliance.

Q: What are the physical dimension differences between the HS150 1R F and HS75 1R F?

A: The HS150 1R F measures 3.846" L × 1.075" W × 0.949" H (97.70mm × 27.30mm × 24.10mm). The HS75 1R F measures 1.917" L × 1.075" W × 0.949" H (48.70mm × 27.30mm × 24.10mm). The HS75 1R F is approximately half the length. Height and width remain consistent for flange mounting compatibility.

Q: Do all substitute parts use the same solder lug lead style?

A: Yes. All listed parts (HS150 1R F Ohmite, HS150 1R F ARCOL, and HS75 1R F ARCOL) use solder lugs as the lead style and are packaged as axial, box type components.

Q: What compliance certifications apply to these parts?

A: The HS150 1R F (Ohmite) and HS75 1R F (ARCOL) are ROHS3 Compliant. The HS150 1R F (ARCOL) is RoHS Compliant. All parts are classified as EAR99 for export control purposes.
