Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK-HKA is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Current Rating: 15 A
• Voltage Rating: 250V
• Fuse Size: 0.25" Dia x 1.26" L (6.35mm x 32mm)
• Fuse Type: Cartridge
• Number of Circuits: 1
• Mounting Type: Panel Mount
• Termination Style: Solder Lug
• Compatible Fuse Standard: 3AG, 1/4" x 1-1/4" (SFE-20)

The BK-HKL-X meets all critical substitution criteria and is classified as an active product, making it a direct functional equivalent to the obsolete BK-HKA. Both components are manufactured by Eaton - Electronics Division within the HK series and share identical electrical ratings, mechanical dimensions, and termination characteristics.

Engineering Selection Recommendations

The BK-HKL-X is the direct substitute for the obsolete BK-HKA. Selection of BK-HKL-X is based on the following engineering factors:

Product Status: The BK-HKL-X is classified as active, ensuring ongoing availability and supply chain support. The BK-HKA is obsolete and subject to discontinuation.

Electrical and Mechanical Equivalence: Both components share identical current ratings (15 A), voltage ratings (250V), fuse dimensions (0.25" Dia x 1.26" L), and termination methods (solder lug). No circuit redesign or mechanical modification is required.

Compliance Alignment: Both components carry identical RoHS status, ECCN classification, and HTSUS codes, ensuring regulatory and trade compliance consistency.

Packaging Consideration: The BK-HKL-X is supplied in bulk packaging, whereas the BK-HKA packaging specification is not provided. Bulk packaging does not affect functional performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can BK-HKL-X be used as a direct replacement for BK-HKA without circuit modification?

A: Yes. The BK-HKL-X is electrically and mechanically equivalent to the BK-HKA. Both components have identical current ratings (15 A), voltage ratings (250V), fuse dimensions (0.25" Dia x 1.26" L), mounting type (panel mount), and termination style (solder lug). No circuit redesign is required.

Q: What fuse types are compatible with both BK-HKA and BK-HKL-X?

A: Both fuse holders are designed for 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (SFE-20 standard). Fuse selection must maintain the 15 A current rating and 250V voltage rating.

Q: Why is the BK-HKA listed as obsolete?

A: The BK-HKA has been discontinued by Eaton - Electronics Division. The BK-HKL-X is the active equivalent product and is recommended for new designs and ongoing production support.

Q: Are there any compliance differences between BK-HKA and BK-HKL-X?

A: No. Both components share identical RoHS status (non-compliant), ECCN classification (EAR99), and HTSUS codes (8538.90.8180). Regulatory and trade compliance requirements are equivalent.

Q: Does packaging type affect the performance of BK-HKL-X?

A: No. The BK-HKL-X is supplied in bulk packaging. Packaging type does not affect electrical performance, mechanical fit, or functional characteristics of the fuse holder.

Q: What is the moisture sensitivity level for these fuse holders?

A: Both BK-HKA and BK-HKL-X have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life with no special moisture control requirements during storage or handling.
