HS150 150R F Equivalent & Substitute Parts

Part Overview

The HS150 150R F is a 150 Ohms ±1% 150W wirewound chassis mount resistor manufactured by Ohmite. This component is designed for high-power applications requiring stable resistance values with pulse withstanding capability. The part is currently in active production status with 1013 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in the same application circuit.

Key Parameters

Substitute Part Grouping Explanation

The HS100 150R F qualifies as a parametric equivalent based on the following criteria:

Identical resistance value: 150 Ohms
Identical tolerance: ±1%
Identical composition: Wirewound
Identical temperature coefficient: ±100ppm/°C
Identical mounting feature: Flanges
Identical lead style: Solder Lugs
Identical housing type: Aluminum
Identical package type: Axial, Box

The primary difference is the power rating: the HS100 150R F is rated at 100W compared to the main part's 150W rating. This substitution is valid only in applications where the circuit power dissipation does not exceed 100W.

Engineering Selection Recommendations

The HS100 150R F serves as a substitute for the HS150 150R F when circuit power dissipation remains below 100W. Both parts maintain identical electrical characteristics including resistance, tolerance, and temperature coefficient. The HS100 150R F features a smaller physical footprint (65.20mm x 27.30mm versus 97.70mm x 47.50mm) while maintaining the same seated height of 24.10mm. Both parts are RoHS compliant and manufactured by Ohmite with active product status. Selection between these parts depends solely on the maximum power dissipation requirement of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the HS100 150R F replace the HS150 150R F in all applications?

A: The HS100 150R F is suitable only for applications where power dissipation does not exceed 100W. Applications requiring power dissipation between 100W and 150W must use the HS150 150R F.

Q: Are the physical dimensions compatible for PCB layout?

A: The HS100 150R F has a smaller footprint (65.20mm x 27.30mm) compared to the HS150 150R F (97.70mm x 47.50mm). Both maintain identical seated height of 24.10mm. PCB layout must accommodate the smaller dimensions of the substitute part.

Q: Do both parts have identical electrical specifications?

A: Yes. Both parts share identical resistance (150 Ohms), tolerance (±1%), composition (Wirewound), temperature coefficient (100ppm/°C), and lead style (Solder Lugs).

Q: What is the compliance status of both parts?

A: The HS150 150R F is RoHS Compliant. The HS100 150R F is ROHS3 Compliant. Both parts meet environmental compliance requirements.

Q: Are both parts available in the same packaging?

A: Both parts use Axial, Box package type. The HS150 150R F is supplied in Box packaging, while the HS100 150R F is supplied in Bulk packaging.
