BK/HKP Cartridge Fuse Holder 30A 250V Panel Mount

Part Overview

The BK/HKP is a cartridge fuse holder manufactured by Eaton - Electronics Division, rated for 30 amperes at 250 volts with single-circuit panel mount configuration. This component is designed for use with 3AG cartridge fuses measuring 0.25" diameter by 1.26" length (6.35mm x 32mm). The BK/HKP is classified as obsolete product status, necessitating identification of equivalent and substitute components for ongoing procurement and system maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/HKP is determined by the following critical parameters: current rating, voltage rating, fuse size, fuse type, number of circuits, mounting type, and termination style. These parameters establish functional and mechanical compatibility within the application circuit.

Direct Equivalent Substitute: BK/HKP-R maintains identical specifications across all critical parameters, including 30A current rating, 250V voltage rating, cartridge fuse type, single-circuit configuration, panel mount orientation, and solder lug termination. The primary distinction is product status classification as active rather than obsolete.

Similar Substitute with Parameter Variance: 03453LF2H (Littelfuse) shares identical voltage rating, fuse size, fuse type, number of circuits, and mounting type. However, this component operates at 20A current rating rather than 30A, and features quick connect termination (0.187" / 4.7mm) instead of solder lug termination. These differences establish this component as a similar substitute suitable only for applications where 20A current capacity is acceptable and quick connect termination is compatible with the circuit design.

Parameter Comparison

Engineering Selection Recommendations

BK/HKP-R (Direct Equivalent): This component is the primary substitute for the obsolete BK/HKP. It maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance certification. Selection of BK/HKP-R is appropriate for direct replacement applications requiring no circuit modification.

03453LF2H (Similar Substitute): This Littelfuse component is suitable for applications where the circuit design accommodates 20A current rating and quick connect termination methodology. The reduced current rating establishes this component as a downrating substitute. Selection requires verification that the application circuit operates within 20A maximum current parameters and that quick connect termination is compatible with existing PCB or panel mount infrastructure.

Both substitute components maintain identical voltage rating, fuse size, fuse type, and single-circuit configuration as the main part. Both substitute components carry ROHS3 compliance and REACH unaffected status certifications.

Frequently Asked Questions (FAQ)

Q: Can BK/HKP-R be used as a direct replacement for BK/HKP?

A: Yes. BK/HKP-R maintains identical specifications for current rating (30A), voltage rating (250V), fuse size (0.25" x 1.26"), fuse type (cartridge), number of circuits (1), mounting type (panel mount), and termination style (solder lug). The primary difference is product status classification; BK/HKP-R is active while BK/HKP is obsolete.

Q: What are the limitations of using 03453LF2H as a substitute?

A: The 03453LF2H operates at 20A current rating compared to the 30A rating of BK/HKP. This component is suitable only for applications where circuit current requirements do not exceed 20A. Additionally, 03453LF2H features quick connect termination (0.187" / 4.7mm) rather than solder lug termination, requiring compatibility verification with the circuit connection methodology.

Q: Are all substitute parts RoHS compliant?

A: Yes. BK/HKP carries RoHS compliance certification. BK/HKP-R and 03453LF2H both carry ROHS3 compliance certification, which represents an enhanced RoHS standard. All components are suitable for applications requiring RoHS compliance.

Q: What is the difference between solder lug and quick connect termination?

A: Solder lug termination (BK/HKP and BK/HKP-R) requires soldering the component leads directly to PCB pads or circuit connections. Quick connect termination (03453LF2H) uses a 0.187" (4.7mm) spade connector that slides onto mating pins, eliminating the soldering requirement. Circuit design must accommodate the specific termination style selected.

Q: Can I use 03453LF2H in a 30A circuit?

A: No. The 03453LF2H is rated for maximum 20A current. Using this component in a 30A circuit exceeds its current rating specification and creates a safety hazard. Component selection must match or exceed the circuit current requirements.

Q: What packaging options are available?

A: BK/HKP-R is supplied in box packaging. 03453LF2H is supplied in bulk packaging. Packaging selection depends on procurement quantity requirements and inventory management protocols.
