HS15 33R J Wirewound Chassis Mount Resistor – Equivalent & Substitute Parts

Part Overview

The HS15 33R J is a 33 Ohms ±5% 15W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is designed for applications requiring high power dissipation with stable resistance values and mechanical robustness through aluminum housing and flanged mounting. The part is currently active in production with 900 pieces in stock. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and compliance certifications to ensure direct interchangeability in circuit designs.

Substitute Part Grouping Explanation

Substitution for the HS15 33R J is determined by matching the following critical parameters:

• Resistance value: 33 Ohms
• Tolerance: ±5%
• Power rating: 15W
• Composition: Wirewound
• Temperature coefficient: ±100ppm/°C
• Housing material: Aluminum
• Mounting configuration: Flanged
• Lead termination: Solder Lugs
• Package classification: Axial, Box

The identified substitute part maintains all electrical specifications and mechanical mounting characteristics. Dimensional variations within the width parameter do not affect functional interchangeability when the height, length, and flanged mounting interface remain consistent.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite HS15 33R J and ARCOL HS15 33R J are active production components with full compliance certifications. The Ohmite variant carries ROHS3 compliance with REACH Unaffected status. The ARCOL variant carries RoHS compliance with Pulse Withstanding feature designation and 1 (Unlimited) MSL rating. Selection between these parts should be based on supply chain availability, compliance requirements specific to the end application, and inventory status. Both parts are electrically and mechanically interchangeable for the specified 33 Ohms ±5% 15W wirewound chassis mount resistor application.

Frequently Asked Questions (FAQ)

Q: Can the ARCOL HS15 33R J directly replace the Ohmite HS15 33R J?

A: Yes. Both parts share identical electrical specifications (33 Ohms ±5%, 15W, ±100ppm/°C), composition (wirewound), and mechanical mounting configuration (aluminum housing, flanged, solder lugs). The parts are functionally interchangeable.

Q: What is the significance of the width dimension difference (0.440" vs 0.827")?

A: The width variation does not affect interchangeability. The critical mounting dimensions—length (0.783"), height (0.433"), and flanged interface—remain identical. Width differences accommodate internal construction variations while maintaining the same electrical performance and mounting footprint.

Q: Are there compliance differences between the two parts?

A: The Ohmite variant is ROHS3 Compliant with REACH Unaffected status. The ARCOL variant is RoHS Compliant with Vendor Undefined REACH status. Both carry EAR99 ECCN classification. Application-specific compliance requirements should determine selection.

Q: What does the Pulse Withstanding feature on the ARCOL part indicate?

A: Pulse Withstanding indicates the ARCOL variant is rated to handle transient overvoltage or overcurrent pulses without degradation. This is an additional capability; its absence on the Ohmite variant does not indicate incompatibility for standard applications.

Q: How do I verify mechanical fit in my PCB layout?

A: Both parts use identical length (19.90mm) and height (11.00mm) dimensions with flanged mounting. Verify that your PCB mounting holes and clearances accommodate the flanged interface. Width differences do not affect hole spacing or mounting alignment.
