HS50 15R J Wirewound Chassis Mount Resistor - Equivalent & Substitute Parts

Part Overview

The HS50 15R J is a 15 Ohms ±5% 50W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is an active product with 938 units in stock. The part features aluminum housing with flanged mounting and solder lug termination, designed for applications requiring high power dissipation in a compact form factor. Substitute parts are identified based on matching resistance value, composition type, and mechanical compatibility while allowing variation in power rating and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS50 15R J is determined by the following mandatory parameters:

• Resistance Value: Must be 15 Ohms (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)
• Temperature Coefficient: Must be ±100ppm/°C (exact match required)

Allowable variations in substitute parts:

• Power Rating: May be 25W or 50W (lower power ratings acceptable for reduced thermal load applications)
• Tolerance: May be ±5% or ±1% (tighter tolerance acceptable for improved accuracy)
• Manufacturer: May vary within ARCOL HS series
• Compliance Certifications: May vary (RoHS3 or RoHS Compliant both acceptable)

Parameter Comparison

Engineering Selection Recommendations

HS50 15R F (ARCOL) — Direct power-rated equivalent with improved tolerance. Maintains 50W power rating and identical length dimension (49.10mm). Tolerance specification of ±1% provides superior accuracy compared to the ±5% main part. RoHS Compliant certification meets regulatory requirements. Suitable for applications where tighter resistance tolerance is required without thermal derating.

HS25 15R J (ARCOL) — Reduced power rating equivalent with matching tolerance. Provides 25W power dissipation capacity with identical ±5% tolerance specification. Compact form factor with 27.30mm length. RoHS Compliant. Applicable for lower thermal load applications or space-constrained designs where 50W capacity is not required.

HS25 15R F (Ohmite) — Reduced power rating with improved tolerance. Combines 25W power rating with ±1% tolerance specification. Maintains ROHS3 Compliant status matching the main part. Compact dimensions (27.30mm length, 14.20mm width). Suitable for applications requiring both reduced thermal dissipation and improved accuracy.

All substitute parts maintain identical resistance value (15 Ohms), wirewound composition, aluminum housing, flanged mounting, and solder lug termination. All parts are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can HS25 15R J be used in place of HS50 15R J?

A: Yes, if the application thermal load does not exceed 25W. The HS25 15R J maintains identical resistance, tolerance, composition, and mechanical mounting specifications. Verify that the reduced power rating is acceptable for your circuit requirements.

Q: What is the difference between ±5% (J) and ±1% (F) tolerance specifications?

A: The tolerance designation indicates the allowable resistance deviation from the nominal 15 Ohm value. ±5% allows deviation between 14.25 and 15.75 Ohms. ±1% allows deviation between 14.85 and 15.15 Ohms. Select ±1% tolerance when circuit performance requires tighter resistance accuracy.

Q: Are there dimensional compatibility concerns when substituting HS50 15R F for HS50 15R J?

A: Both parts maintain identical length (49.10mm) and height (14.80mm). The HS50 15R F width is 28.00mm compared to 14.20mm for the HS50 15R J. Verify mounting clearance in your application before substitution.

Q: Do all substitute parts meet the same RoHS compliance requirements?

A: The main part HS50 15R J is ROHS3 Compliant. Substitute parts HS50 15R F and HS25 15R J are RoHS Compliant. HS25 15R F is ROHS3 Compliant. All parts meet regulatory compliance for electronic component use.

Q: Which substitute part offers the best combination of availability and performance?

A: HS25 15R J offers the highest inventory (2100 units) with matching tolerance specification (±5%). HS50 15R F provides the same power rating as the main part with improved tolerance (±1%) and 766 units in stock.

Q: Can HS50 15R J be substituted with a lower power rating part in all applications?

A: No. Substitution with lower power rating parts (HS25 series) is only valid when the application thermal load does not exceed the substitute part's power rating. Exceeding the power rating will cause component failure. Verify thermal requirements before selecting a lower-rated substitute.
