HS25 15R J Equivalent & Substitute Parts

Part Overview

The HS25 15R J is a 15 Ohms ±5% 25W wirewound chassis mount resistor manufactured by Ohmite in the ARCOL HS series. This component is classified as Active and is currently in production. The HS25 15R J features an aluminum housing with flanged mounting, solder lug termination, and is designed for applications requiring reliable power dissipation in compact form factors. Equivalent and substitute parts are identified when electrical parameters, mechanical dimensions, and compliance certifications align with the original specification, enabling direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS25 15R J are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Core Electrical Parameters: Resistance value (15 Ohms), power rating (25W), and composition (wirewound) must be identical. Tolerance variations are permitted only when the substitute tolerance is equal to or tighter than the original specification.

Mechanical Compatibility: Housing type (aluminum), mounting feature (flanges), lead style (solder lugs), and package configuration (axial, box) must match the original part to ensure direct mechanical and electrical fit.

Compliance & Certification: RoHS and REACH compliance status are evaluated to confirm regulatory alignment with the original specification.

Two substitute parts meet these criteria:

1. HS25 15R J (ARCOL manufacturer variant) — Identical electrical specifications with pulse withstanding feature. Dimensions vary slightly in width (28.00mm vs. 14.20mm), but height and length remain consistent. RoHS compliant with MSL rating of 1 (Unlimited).

2. HS25 15R F (Ohmite) — Tighter tolerance variant (±1% vs. ±5%) with identical resistance, power rating, and mechanical form factor. Maintains ROHS3 compliance and identical dimensions to the original HS25 15R J.

Parameter Comparison

Engineering Selection Recommendations

HS25 15R J (ARCOL) is a direct electrical equivalent with identical tolerance and power rating. This variant is suitable for applications where the original Ohmite HS25 15R J is specified, provided that the ARCOL manufacturer designation is acceptable within the design documentation. The pulse withstanding feature provides additional robustness in transient-heavy applications. REACH status is listed as vendor undefined; confirmation with the supplier is recommended for applications subject to REACH compliance verification.

HS25 15R F (Ohmite) offers tighter tolerance (±1%) compared to the original ±5% specification. This substitute is appropriate for applications requiring improved resistance accuracy without changing the manufacturer or core mechanical form factor. ROHS3 and REACH compliance status matches the original part, ensuring regulatory alignment. The tighter tolerance may introduce cost considerations relative to the standard tolerance variant.

Selection between substitutes depends on tolerance requirements, manufacturer preference, and compliance documentation needs. Both parts maintain identical mechanical fit and electrical power handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can the HS25 15R F (±1% tolerance) be used as a direct replacement for the HS25 15R J (±5% tolerance)?

A: Yes. The HS25 15R F is electrically and mechanically compatible. The tighter tolerance of ±1% is a superior specification that does not compromise circuit performance. Both parts share identical resistance value, power rating, temperature coefficient, housing type, mounting features, and physical dimensions.

Q: What is the difference between the Ohmite HS25 15R J and the ARCOL HS25 15R J?

A: Both parts are electrically identical with 15 Ohms ±5% 25W specifications. The ARCOL variant includes a pulse withstanding feature and has a slightly wider dimension (28.00mm vs. 14.20mm width). Height and length dimensions remain consistent. Both are RoHS compliant and suitable for direct substitution in applications where the manufacturer designation is not restricted.

Q: Are there any mechanical fit concerns when substituting the ARCOL HS25 15R J?

A: The ARCOL variant has a different width dimension (1.102" vs. 0.559"). Verify that the circuit board layout and mounting bracket accommodate this dimensional change before implementation. Length and height remain unchanged, so vertical and axial clearances are unaffected.

Q: Do all three parts meet the same compliance standards?

A: The Ohmite HS25 15R J and HS25 15R F are both ROHS3 compliant and REACH unaffected. The ARCOL HS25 15R J is RoHS compliant with vendor-undefined REACH status. For applications requiring explicit REACH compliance documentation, the Ohmite variants are preferred.

Q: What inventory considerations apply to these substitutes?

A: The Ohmite HS25 15R J and ARCOL HS25 15R J each have 2100 pieces in stock. The Ohmite HS25 15R F has 763 pieces available. Inventory levels should be confirmed at the time of procurement to ensure supply continuity.
