Equivalent & Substitute Parts for BK/HHF-B Blade Fuse Holder

Part Overview

The BK/HHF-B is a 16 A, 32V blade fuse holder manufactured by Eaton - Electronics Division, designed for in-line, free-hanging mounting applications with ATC and ATO blade fuses. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The HHF series fuse holder provides single-circuit protection in compact form factor suitable for automotive and industrial electrical systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete BK/HHF-B is determined by strict equivalence across all electrical and mechanical parameters. The substitute part HHF-JFCU maintains identical specifications for current rating (16 A), voltage rating (32V), fuse type (blade), fuse size (0.75" L x 0.2" W), circuit count (1), mounting configuration (free hanging in-line), and termination style (wire leads). Both parts are compatible with ATC and ATO blade fuses. The primary distinction is product status: BK/HHF-B is obsolete while HHF-JFCU is active, with HHF-JFCU offering additional compliance certifications (RoHS3 Compliant, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

The HHF-JFCU is the direct active equivalent for the obsolete BK/HHF-B blade fuse holder. Both components share identical electrical ratings (16 A, 32V), mechanical dimensions (0.75" L x 0.2" W), and functional specifications. Selection of HHF-JFCU is supported by its active product status and compliance certifications: RoHS3 Compliant and REACH Unaffected. The HHF-JFCU is available in bulk packaging with 2418 units in stock, compared to 885 units of the obsolete BK/HHF-B. For new designs or system replacements, HHF-JFCU is the appropriate choice. For legacy system maintenance requiring exact form-factor and performance match, HHF-JFCU provides full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can HHF-JFCU directly replace BK/HHF-B in existing applications?

A: Yes. HHF-JFCU is electrically and mechanically equivalent to BK/HHF-B across all specified parameters: 16 A current rating, 32V voltage rating, blade fuse type, identical fuse size (0.75" L x 0.2" W), single-circuit configuration, free-hanging in-line mounting, and wire lead termination. Both accept ATC and ATO blade fuses.

Q: What is the primary reason to transition from BK/HHF-B to HHF-JFCU?

A: BK/HHF-B is classified as obsolete. HHF-JFCU is the active equivalent part from the same manufacturer (Eaton - Electronics Division) and HHF series, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between the two parts?

A: HHF-JFCU carries RoHS3 Compliant and REACH Unaffected certifications. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, and both have MSL rating of 1 (Unlimited).

Q: What is the packaging difference?

A: BK/HHF-B is listed with packaging designation "-" (not specified), while HHF-JFCU is supplied in bulk packaging. HHF-JFCU has higher inventory availability (2418 units vs. 885 units).

Q: Are the fuse compatibility standards identical?

A: Yes. Both BK/HHF-B and HHF-JFCU are compatible with ATC and ATO blade fuses, maintaining full interchangeability in fuse selection.
