HS150 30R F Equivalent & Substitute Parts

Part Overview

The HS150 30R F is a 150-watt wirewound chassis mount resistor manufactured by Ohmite, rated at 30 ohms with ±1% tolerance. This component is designed for high-power applications requiring reliable thermal dissipation and pulse withstanding capability. The part is currently in active production status with 1047 units available in new original stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS150 30R F is determined by the following critical parameters:

• Resistance Value: Must be 30 Ohms
• Tolerance: Must be ±1%
• Composition: Must be Wirewound
• Housing Type: Must be Aluminum
• Mounting Feature: Must include Flanges
• Lead Style: Must be Solder Lugs

The HS100 30R F qualifies as a parametric equivalent based on matching resistance, tolerance, composition, housing, mounting, and lead style specifications. The primary difference is the power rating (100W versus 150W), which represents a downrating in thermal capacity. This substitution is valid only when circuit power dissipation requirements do not exceed 100 watts.

Parameter Comparison

Engineering Selection Recommendations

Both the HS150 30R F and HS100 30R F are active production components from Ohmite with full RoHS compliance. Selection between these parts is determined by circuit power dissipation requirements. The HS150 30R F is specified for applications requiring 150-watt thermal capacity. The HS100 30R F is suitable for applications with maximum power dissipation of 100 watts. Both components share identical electrical specifications (30 ohms, ±1% tolerance) and mechanical mounting interfaces (flanges, solder lugs, aluminum housing). The HS100 30R F occupies a smaller physical footprint, which may be advantageous in space-constrained designs operating within its 100-watt power envelope.

Frequently Asked Questions (FAQ)

Q: Can the HS100 30R F replace the HS150 30R F in all applications?

A: The HS100 30R F is electrically equivalent but thermally downrated. Substitution is valid only when circuit power dissipation does not exceed 100 watts. Applications requiring sustained power dissipation above 100 watts must use the HS150 30R F.

Q: Are the physical dimensions compatible between these parts?

A: Both components share identical height (0.949" maximum seated height) and mounting flange specifications. The HS100 30R F has reduced length and width dimensions. Mechanical fit must be verified for the specific application mounting location.

Q: Do both parts meet current RoHS requirements?

A: Yes. The HS150 30R F is RoHS Compliant. The HS100 30R F is ROHS3 Compliant. Both meet current environmental compliance standards.

Q: What is the temperature coefficient difference between these parts?

A: The HS150 30R F specifies 100ppm/°C. The HS100 30R F specifies ±100ppm/°C. Both values are within standard wirewound resistor specifications for this resistance and power class.

Q: Are solder lug connections identical between both parts?

A: Yes. Both components use solder lug lead style and are compatible with identical PCB or chassis mounting interfaces.
