Eaton BK/HPF Cartridge Fuse Holder 20A 600V Panel Mount - Equivalent & Substitute Parts

Part Overview

The Eaton BK/HPF is a cartridge fuse holder rated for 20A at 600V, designed for single-circuit panel mount applications. This component is classified as Active product status and is RoHS Compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required for system compatibility, inventory availability, or supply chain continuity while maintaining the same functional performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Eaton BK/HPF is determined by the following critical parameters:

• Voltage Rating: 600V (exact match required)
• Fuse Size: 0.394" Dia x 1.496" L (10mm x 38mm) (exact match required)
• Fuse Type: Cartridge, 5AG Midget format (exact match required)
• Number of Circuits: 1 (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Termination Style: Quick Connect - 0.250" (6.3mm) (exact match required)

The substitute part Littelfuse 05710007L shares all critical mechanical and electrical parameters with the main part. The current rating difference (30A vs 20A) represents a higher capacity rating within the same physical form factor and does not preclude substitution in applications where the 20A rating is specified, as the holder accommodates the same fuse cartridge dimensions and voltage class.

Parameter Comparison

Engineering Selection Recommendations

Both the Eaton BK/HPF and Littelfuse 05710007L maintain Active product status and meet applicable compliance requirements. The Eaton part carries RoHS Compliant certification, while the Littelfuse substitute carries ROHS3 Compliant certification, indicating compliance with the most current RoHS directive iteration. Both parts are classified under ECCN EAR99 for export control purposes.

Selection between these parts should be based on availability, supply chain requirements, and specific application current rating needs. The mechanical and electrical compatibility is established through identical fuse size, voltage rating, cartridge type, mounting configuration, and termination style.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 05710007L replace the Eaton BK/HPF in a 20A circuit application?

A: The Littelfuse 05710007L is mechanically and electrically compatible with the Eaton BK/HPF. Both holders accept the same 5AG cartridge fuse format at 600V with identical physical dimensions and quick-connect termination. The 30A rating of the Littelfuse holder does not prevent its use in a 20A application; the actual circuit protection is determined by the fuse cartridge installed in the holder, not the holder's rated capacity.

Q: What are the critical compatibility parameters for substitution?

A: Substitution requires exact matching of: voltage rating (600V), fuse size (10mm x 38mm), fuse type (5AG Cartridge), number of circuits (1), mounting type (Panel Mount), and termination style (Quick Connect 0.250"). Deviation in any of these parameters indicates incompatibility.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The Eaton part carries RoHS Compliant certification, while the Littelfuse part carries ROHS3 Compliant certification, representing the latest RoHS directive requirements. Both are suitable for applications requiring RoHS compliance.

Q: What is the significance of the contact material and finish specifications?

A: The Littelfuse 05710007L specifies Brass contact material with Tin finish. The Eaton BK/HPF does not provide these specifications in the available data. Contact material and finish affect electrical conductivity and corrosion resistance. Brass with Tin finish is a standard industrial specification for cartridge fuse holder contacts and ensures reliable electrical connection and long-term performance.

Q: How does packaging affect part selection?

A: Both parts are supplied in Bulk packaging. Inventory availability shows 897 pieces for the Eaton BK/HPF and 1187 pieces for the Littelfuse 05710007L. Packaging format does not affect electrical or mechanical compatibility; selection may be influenced by required order quantities and supply chain lead times.
