Eaton BK/HRJ Cartridge Fuse Holder 32V 20A Equivalent & Substitute Parts

Part Overview

The Eaton BK/HRJ is a cartridge fuse holder rated for 20 amperes at 32 volts, configured as a free-hanging in-line assembly with wire lead termination. This component is designed to accommodate 0.25" diameter by 1.26" length cartridge fuses (6.35mm x 32mm), specifically compatible with 3AG and 1/4" x 1-1/4" fuse types such as the SFE-20. The product maintains active status within Eaton's Electronics Division portfolio. Equivalent substitute parts are identified based on matching electrical ratings, mechanical dimensions, fuse compatibility, and termination characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Eaton BK/HRJ fuse holder is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Current rating (20 A) and voltage rating (32V) must match exactly. These values define the safe operating envelope for the fuse holder assembly.

Mechanical Parameters: Fuse size dimensions (0.25" diameter x 1.26" length) and cartridge fuse type must be identical to ensure physical fit and electrical contact integrity.

Functional Parameters: Mounting configuration (free-hanging in-line), number of circuits (1), and termination style (wire leads) must correspond to maintain compatibility with the circuit design and installation method.

Fuse Compatibility: The substitute must accept the same fuse standards (3AG, 1/4" x 1-1/4", SFE-20) to ensure interchangeability at the component level.

The Littelfuse 01550020ZXA meets all these criteria and is identified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Eaton BK/HRJ): Use when existing designs specify Eaton components or when RoHS non-compliant status is acceptable for the application. Product is active and available in inventory (1156 pcs).

Substitute Selection (Littelfuse 01550020ZXA): Use when RoHS3 compliance is required by design specifications or regulatory requirements. The Littelfuse part maintains electrical and mechanical equivalence while offering improved environmental compliance. Product is active and available in inventory (1328 pcs).

Compliance Consideration: The primary difference between these parts is RoHS compliance status. The Littelfuse 01550020ZXA is ROHS3 compliant, whereas the Eaton BK/HRJ is RoHS non-compliant. Both parts are REACH Unaffected and classified under the same ECCN and HTSUS codes, indicating equivalent regulatory treatment in export and trade contexts.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 01550020ZXA directly replace the Eaton BK/HRJ in existing assemblies?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current ratings (20 A), voltage ratings (32V), fuse dimensions (0.25" x 1.26"), mounting configuration (free-hanging in-line), and wire lead termination. Both accept 3AG and 1/4" x 1-1/4" cartridge fuses.

Q: What is the primary difference between these two fuse holders?

A: The Littelfuse 01550020ZXA is ROHS3 compliant, while the Eaton BK/HRJ is RoHS non-compliant. All other electrical, mechanical, and regulatory parameters are equivalent.

Q: Are there any contact material or finish differences?

A: The Littelfuse 01550020ZXA specifies brass contact material with tin finish. The Eaton BK/HRJ does not provide contact material or finish specifications in the available data. This does not affect functional equivalence for the specified electrical ratings and fuse compatibility.

Q: Which fuse types are compatible with both holders?

A: Both holders accept 3AG and 1/4" x 1-1/4" cartridge fuses, specifically including the SFE-20 fuse type. The mechanical dimensions (0.25" diameter x 1.26" length) ensure compatibility with these standard fuse formats.

Q: Are both parts currently in production?

A: Yes. Both the Eaton BK/HRJ and Littelfuse 01550020ZXA maintain active product status. Inventory availability is confirmed: Eaton BK/HRJ (1156 pcs) and Littelfuse 01550020ZXA (1328 pcs).

Q: Do these parts have the same export classification?

A: Yes. Both parts are classified under ECCN EAR99 and HTSUS code 8538.90.8180, indicating equivalent treatment for export control and tariff purposes.
