HS150 33R J Equivalent & Substitute Parts

Part Overview

The HS150 33R J is a 33 Ohms ±5% 150W wirewound chassis mount resistor manufactured by Ohmite, part of the ARCOL HS series. This component is designed for high-power applications requiring stable resistance values with aluminum housing and flanged mounting. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical parameters and mechanical compatibility allow direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

The HS100 33R J qualifies as a parametric equivalent based on the following matching criteria:

Matching Parameters:

• Resistance value: 33 Ohms (identical)
• Tolerance: ±5% (identical)
• Composition: Wirewound (identical)
• Temperature Coefficient: ±100ppm/°C (identical)
• Housing Type: Aluminum (identical)
• Mounting Feature: Flanges (identical)
• Lead Style: Solder Lugs (identical)
• Package Type: Axial, Box (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Manufacturer: Ohmite (identical)
• Series: ARCOL HS (identical)

Differing Parameter:

• Power Rating: HS100 33R J rated at 100W versus HS150 33R J rated at 150W

The HS100 33R J represents a lower power variant within the same product family. Substitution is valid only in applications where the 100W power rating meets or exceeds the circuit requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the HS150 33R J and HS100 33R J maintain Active product status with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these components depends solely on power dissipation requirements in the target application.

The HS150 33R J is the primary selection for applications requiring the full 150W power rating. The HS100 33R J serves as a substitute only when circuit power dissipation does not exceed 100W. Both components share identical electrical characteristics (33 Ohms ±5%, ±100ppm/°C temperature coefficient) and mechanical mounting interfaces (flanged aluminum housing with solder lugs).

Physical dimensions differ: the HS100 33R J is shorter (2.566" versus 3.846" length) while maintaining identical width and height dimensions. This dimensional difference must be evaluated against available board space and thermal management requirements.

Frequently Asked Questions (FAQ)

Q: Can the HS100 33R J replace the HS150 33R J in all applications?

A: No. The HS100 33R J is suitable only for applications where power dissipation does not exceed 100W. If the circuit requires or may require power dissipation above 100W, the HS150 33R J must be used.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both components provide 33 Ohms ±5% resistance with ±100ppm/°C temperature coefficient. Electrical performance is equivalent when power requirements are within the HS100 33R J rating.

Q: Do these parts have the same mounting interface?

A: Yes. Both components feature aluminum housing with flanged mounting and solder lugs. Mounting compatibility is identical.

Q: What is the physical size difference?

A: The HS100 33R J is shorter (2.566" length) compared to the HS150 33R J (3.846" length). Width and height dimensions are identical. Verify available board space before substitution.

Q: Are both parts compliant with current regulations?

A: Yes. Both the HS150 33R J and HS100 33R J are ROHS3 Compliant and REACH Unaffected, with Active product status.

Q: What determines whether substitution is acceptable?

A: Substitution is determined by power dissipation requirements. Calculate circuit power dissipation (P = I²R or P = V²/R). If dissipation is ≤100W, the HS100 33R J is acceptable. If dissipation exceeds 100W, the HS150 33R J is required.
