HS50 R15 J Equivalent & Substitute Parts

Part Overview

The HS50 R15 J is a 50-watt wirewound chassis mount resistor manufactured by Ohmite, rated at 150 mOhms with ±5% tolerance. This component is designed for high-power applications requiring pulse withstanding capability and thermal stability. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance is required within the constraints of available power ratings and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS50 R15 J is determined by the following mandatory parameters:

• Resistance Value: Must be 150 mOhms (exact match required)
• Tolerance: Must be ±5% (exact match required)
• Composition: Must be Wirewound (exact match required)
• Housing Type: Must be Aluminum (exact match required)
• Mounting Feature: Must be Flanges (exact match required)
• Lead Style: Must be Solder Lugs (exact match required)
• RoHS Compliance: Must maintain RoHS compliance status

The HS25 R15 J qualifies as a parametric equivalent under these criteria. The primary difference is the power rating (25W versus 50W), which represents a derating scenario where the substitute part operates within reduced thermal envelope specifications.

Parameter Comparison

Engineering Selection Recommendations

The HS25 R15 J is an Active product with ROHS3 compliance, meeting current environmental standards. Selection between HS50 R15 J and HS25 R15 J depends on circuit power dissipation requirements:

• HS50 R15 J: Select when circuit design requires 50W continuous dissipation capacity or when thermal margin is critical for reliability.
• HS25 R15 J: Select when circuit dissipation does not exceed 25W and reduced physical footprint is advantageous for board layout. This part provides identical electrical performance within its power rating specification.

Both parts maintain identical electrical characteristics (resistance, tolerance, temperature coefficient) and mechanical compatibility (mounting, lead style, height). The substitution is valid only when application power requirements do not exceed the 25W rating of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can HS25 R15 J replace HS50 R15 J in all applications?

A: No. The HS25 R15 J is suitable only for applications where continuous power dissipation does not exceed 25W. If the circuit requires 50W dissipation capacity, the HS50 R15 J must be used.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both parts have 150 mOhms resistance, ±5% tolerance, wirewound construction, and 100 ppm/°C temperature coefficient. Electrical performance is identical within their respective power ratings.

Q: What is the physical difference between these parts?

A: The HS25 R15 J has a smaller footprint (1.075" L x 0.559" W versus 1.933" L x 1.102" W) while maintaining the same seated height of 0.583". Both use aluminum housing with flanged mounting and solder lugs.

Q: Are both parts RoHS compliant?

A: Yes. The HS50 R15 J is RoHS Compliant, and the HS25 R15 J is ROHS3 Compliant. Both meet environmental compliance requirements.
