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

Part Overview

The BK/ABC-V-3 is a 3 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation, designed for through-hole mounting in 3AB/3AG package format with 1/4" x 1-1/4" (Axial) dimensions. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts to maintain circuit protection functionality in existing and new designs. The fast-blow response time and 100 A AC / 10 kA DC breaking capacity establish the baseline performance requirements for substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/ABC-V-3 is determined by strict equivalence across the following critical parameters: current rating (3 A), AC voltage rating (250 V), DC voltage rating (125 V), fuse type (ceramic cartridge), package format (3AB/3AG, 1/4" x 1-1/4"), response time (fast blow), and mounting configuration (through hole). All substitute parts must maintain identical electrical performance under rated conditions and support the same circuit protection requirements.

Substitute parts are grouped into two categories:

Eaton - Electronics Division Direct Equivalents: Parts BK/ABC-V-3-R, ABC-V-3-R, BK/GBB-V-3-R, and GBB-V-3-R are manufactured by Eaton and maintain full parametric equivalence with the obsolete BK/ABC-V-3. These parts are active products with ROHS3 compliance and enhanced availability.

Littelfuse Inc. Cross-Manufacturer Equivalents: Parts 0324003.HXP, 0324003.MXP, and 0324003.VXP are manufactured by Littelfuse and provide functional equivalence across all critical electrical and mechanical parameters. These parts carry expanded approval certifications and extended operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Eaton Direct Equivalents:

BK/ABC-V-3-R and ABC-V-3-R are the preferred substitutes for the obsolete BK/ABC-V-3. Both parts are active products manufactured by Eaton with ROHS3 compliance, CSA and UL certifications matching the original specification, and identical electrical ratings. These parts provide direct form-fit-function replacement with enhanced environmental compliance and current inventory availability.

Secondary Recommendation - Eaton GBB Series:

BK/GBB-V-3-R and GBB-V-3-R offer parametric equivalence with enhanced breaking capacity specifications. GBB-V-3-R provides 200 A AC breaking capacity compared to the original 100 A AC specification, delivering superior fault protection margins. Both parts maintain active product status, ROHS3 compliance, and CSA/UR certifications. These parts are suitable for applications requiring higher fault current withstand capability.

Cross-Manufacturer Alternative - Littelfuse 324 Series:

0324003.HXP, 0324003.MXP, and 0324003.VXP provide functional equivalence with expanded regulatory approvals including CE, K-MARK, PSE, and UL certifications. These parts feature extended operating temperature range (-55°C to 125°C) and REACH compliance. Selection of Littelfuse alternatives is appropriate for applications requiring multi-regional certification or enhanced temperature performance. All three Littelfuse variants maintain identical electrical specifications and are interchangeable within the 3AB/3AG package format.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-V-3-R directly replace the obsolete BK/ABC-V-3 in existing circuit designs?

A: Yes. BK/ABC-V-3-R maintains identical current rating (3 A), voltage ratings (250 V AC / 125 V DC), package format (3AB/3AG, 1/4" x 1-1/4"), response time (fast blow), and breaking capacity (100 A AC / 10 kA DC). The part is a direct form-fit-function replacement with ROHS3 compliance and active product status.

Q: What is the difference between the Eaton ABC-V-3-R and GBB-V-3-R substitutes?

A: Both parts maintain identical current, voltage, and package specifications. The primary difference is breaking capacity: ABC-V-3-R provides 100 A AC breaking capacity, while GBB-V-3-R provides 200 A AC breaking capacity. Selection depends on circuit fault current requirements. GBB-V-3-R is suitable for applications with higher available fault currents.

Q: Are Littelfuse 0324003 series fuses compatible with the original BK/ABC-V-3 mounting footprint?

A: Yes. All Littelfuse 0324003 variants (HXP, MXP, VXP) are packaged in 3AB/3AG format with 1/4" x 1-1/4" (Axial) dimensions, providing mechanical compatibility with the original through-hole mounting configuration. Electrical specifications are identical across all three variants.

Q: What certifications apply to the substitute parts?

A: Eaton ABC-V-3-R and BK/ABC-V-3-R carry CSA and UL certifications. Eaton GBB series parts carry CSA and UR certifications. Littelfuse 0324003 series parts carry CE, CSA, K-MARK, PSE, and UL certifications. All parts meet the original CSA and UL requirements with expanded regional compliance.

Q: Can I use GBB-V-3-R in place of ABC-V-3-R?

A: Yes. GBB-V-3-R is a parametric equivalent with identical current, voltage, package, and response time specifications. The enhanced 200 A AC breaking capacity provides additional fault protection margin and is compatible with all applications designed for the original BK/ABC-V-3.

Q: What is the operating temperature range for substitute parts?

A: Eaton ABC-V-3-R and GBB series parts do not specify an operating temperature range in the provided data. Littelfuse 0324003 series parts operate across -55°C to 125°C. For applications requiring extended temperature performance, Littelfuse variants are appropriate.

Q: Are all substitute parts RoHS compliant?

A: The original BK/ABC-V-3 is RoHS non-compliant. All substitute parts (Eaton ABC-V-3-R, BK/ABC-V-3-R, GBB series, and Littelfuse 0324003 series) are ROHS3 compliant, meeting current environmental regulations.
