HS150 22R F Equivalent & Substitute Parts

Part Overview

The HS150 22R F is a 150-watt wirewound chassis mount resistor manufactured by Ohmite, rated at 22 ohms with ±1% tolerance. This component is designed for high-power applications requiring pulse withstanding capability and thermal stability. The part is currently in active production status with full RoHS compliance. Equivalent and substitute parts are identified when electrical parameters (resistance value, tolerance, power rating, and temperature coefficient) and mechanical specifications (mounting configuration, housing type, and lead style) align within acceptable engineering tolerances for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS150 22R F is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 22 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: 100ppm/°C or equivalent thermal stability
• Composition: Wirewound (required for power handling and stability)

Mechanical Compatibility Requirements:

• Housing type: Aluminum (thermal management requirement)
• Mounting feature: Flanges (mechanical interface requirement)
• Lead style: Solder Lugs (connection interface requirement)
• Package type: Axial configuration with box packaging

Regulatory Compliance:

• RoHS compliance status (RoHS Compliant or ROHS3 Compliant acceptable)

The HS100 22R F qualifies as a parametric equivalent based on matching resistance, tolerance, composition, housing, mounting, and lead specifications. The primary distinction is the power rating differential (100W vs. 150W), which represents a downrating scenario where the substitute part operates at reduced power capacity.

Engineering Selection Recommendations

HS150 22R F (Primary Selection): Use the HS150 22R F when the application requires the full 150-watt power dissipation capacity. This part maintains active production status with RoHS compliance certification, ensuring supply chain continuity and regulatory alignment for current and future deployments.

HS100 22R F (Substitute Selection): The HS100 22R F serves as a substitute only in applications where the actual power dissipation does not exceed 100 watts. Both parts share identical electrical characteristics (22 ohms, ±1% tolerance, wirewound composition) and mechanical interfaces (aluminum housing, flange mounting, solder lugs). The HS100 22R F carries ROHS3 compliance, meeting current regulatory requirements. Physical dimensions differ (HS100 22R F is smaller: 65.20mm L x 27.30mm W vs. HS150 22R F: 97.70mm L x 47.50mm W), requiring verification of available mounting space in the target application.

Frequently Asked Questions (FAQ)

Q: Can the HS100 22R F replace the HS150 22R F in all applications?

A: No. The HS100 22R F is suitable only for applications where actual power dissipation remains below 100 watts. If the circuit design requires 150-watt capacity, the HS150 22R F is the required component. Substitution with a lower-rated part in high-power applications will result in component failure.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Both parts provide 22 ohms at ±1% tolerance with wirewound construction and equivalent temperature coefficients (100ppm/°C and ±100ppm/°C respectively). Electrical performance in the circuit is identical when operating within the HS100 22R F's 100-watt limit.

Q: What are the physical dimension differences?

A: The HS150 22R F measures 97.70mm length x 47.50mm width x 24.10mm height (seated). The HS100 22R F measures 65.20mm length x 27.30mm width x 24.10mm height (seated). The HS100 22R F is approximately 33% smaller in footprint. Verify mounting space availability before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The HS150 22R F carries RoHS Compliant certification. The HS100 22R F carries ROHS3 Compliant certification. Both meet current regulatory requirements for restricted substance elimination.

Q: What is the packaging difference?

A: The HS150 22R F is supplied in box packaging. The HS100 22R F is supplied in bulk packaging. This affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Q: Can the HS150 22R F be used in place of the HS100 22R F?

A: Yes. The HS150 22R F can be used as an upgrade substitute for the HS100 22R F in any application. The higher power rating provides additional thermal margin and reliability headroom. Physical dimensions are larger, requiring verification of available mounting space.
