Equivalent & Substitute Parts for BK/ABC-V-3-R

Part Overview

The BK/ABC-V-3-R is a 3 A ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated for 250 V AC and 125 V DC operation. This through-hole mounted fuse is designed for fast-blow response applications and is currently in active production status. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when supply chain optimization is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/ABC-V-3-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 3 A
• Voltage Rating - AC: 250 V
• Voltage Rating - DC: 125 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Fast Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial)
• Mounting Type: Through Hole
• Breaking Capacity @ Rated Voltage: 100 A AC, 10 kA DC

The substitute part 0324003.HXP manufactured by Littelfuse Inc. meets all mandatory matching parameters and is therefore classified as a direct equivalent for the BK/ABC-V-3-R.

Parameter Comparison

Engineering Selection Recommendations

Both the BK/ABC-V-3-R and 0324003.HXP are active production parts with full regulatory compliance. The Eaton part carries CSA and UL certifications, while the Littelfuse substitute carries expanded certifications including CE, K-MARK, and PSE in addition to CSA and UL. Both parts are ROHS3 compliant and suitable for equivalent circuit protection applications.

The 0324003.HXP substitute is electrically and mechanically compatible with the BK/ABC-V-3-R for all applications requiring a 3 A, 250 V AC / 125 V DC fast-blow ceramic cartridge fuse in 3AB/3AG package format. Selection between these parts may be based on supply availability, lead time, or regional certification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0324003.HXP be used as a direct replacement for the BK/ABC-V-3-R?

A: Yes. Both parts share identical current rating (3 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package format (3AB, 3AG, 1/4" x 1-1/4"), mounting type (through hole), and breaking capacity (100 A AC, 10 kA DC). They are electrically and mechanically equivalent.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The BK/ABC-V-3-R measures 0.266" diameter × 1.292" length, while the 0324003.HXP measures 0.275" diameter × 1.288" length. Both conform to the 3AB, 3AG standard package specification and are compatible with standard fuse holders designed for this package format.

Q: What is the significance of the different Melting I²t values?

A: The Melting I²t parameter (6.55 for Eaton, 14.6 for Littelfuse) reflects internal thermal characteristics but does not affect substitutability. Both parts meet the same fast-blow response time specification and breaking capacity requirements.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and carry UL and CSA certifications. The Littelfuse part carries additional certifications (CE, K-MARK, PSE), which may be advantageous for applications requiring broader regional compliance.

Q: What is the difference in DC Cold Resistance?

A: The BK/ABC-V-3-R has 0.047 Ohms DC cold resistance, while the 0324003.HXP has 0.0432 Ohms. This minor difference does not affect circuit protection performance or substitutability for standard applications.
