Equivalent & Substitute Parts for BK/ABC-V-25

Part Overview

The BK/ABC-V-25 is a 25 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation with fast-blow response characteristics. This component is classified as obsolete, which necessitates identification of active substitute parts that maintain electrical and mechanical compatibility. The fuse features a 3AB/3AG form factor with 1/4" x 1-1/4" axial dimensions and is approved by CSA and UL agencies. Due to its obsolete status, equivalent active alternatives are required for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/ABC-V-25 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 25 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)
• Size / Dimension: 0.266" Dia x 1.292" L (6.76mm x 32.82mm)
• Mounting Type: Through Hole

All identified substitute parts meet these mandatory parameters. Variations in breaking capacity, DC cold resistance, and RoHS compliance status do not affect functional substitution but are documented for system integration considerations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement):

BK/ABC-V-25-R and ABC-V-25-R are direct substitutes within the ABC series. Both parts maintain active product status and are ROHS3 compliant. BK/ABC-V-25-R is available in bulk packaging with 1973 units in stock, while ABC-V-25-R offers 684 units. Both parts are approved by CSA and UL agencies, matching the original certification requirements.

Alternative Substitutes (Series Upgrade):

BK/GBB-V-25-R and GBB-V-25-R represent the GBB series equivalent. These parts are active and ROHS3 compliant with CSA and UR approvals. The GBB series offers enhanced breaking capacity specifications (10kA for BK/GBB-V-25-R and 200A for GBB-V-25-R) and marginally lower DC cold resistance values. GBB-V-25-R provides 1015 units in stock, while BK/GBB-V-25-R offers 932 units.

Compliance Considerations:

All substitute parts are ROHS3 compliant, addressing environmental regulatory requirements that the obsolete BK/ABC-V-25 does not meet. Selection between ABC and GBB series should be based on system breaking capacity requirements and certification preferences (UL versus UR).

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-V-25-R be used as a direct replacement for BK/ABC-V-25?

A: Yes. BK/ABC-V-25-R is a direct substitute with identical electrical ratings (25 A, 250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and mechanical form factor (3AB/3AG, 1/4" x 1-1/4" axial). The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What is the difference between ABC-V-25-R and BK/ABC-V-25-R?

A: Both parts are electrically and mechanically equivalent. The primary distinction is packaging designation: BK/ABC-V-25-R is supplied in bulk packaging, while ABC-V-25-R uses standard packaging. Electrical performance and form factor are identical.

Q: Can GBB-V-25-R replace BK/ABC-V-25?

A: Yes. GBB-V-25-R meets all mandatory substitution parameters: 25 A current rating, 250 V AC / 125 V DC voltage ratings, ceramic cartridge fuse type, fast-blow response, and 3AB/3AG form factor with identical dimensions. The GBB series offers higher breaking capacity (200A) and lower DC cold resistance (0.00252 Ohms versus 0.00263 Ohms).

Q: What is the difference between BK/GBB-V-25-R and GBB-V-25-R?

A: Both parts are electrically and mechanically equivalent GBB series fuses. BK/GBB-V-25-R specifies 10kA breaking capacity, while GBB-V-25-R specifies 200A breaking capacity. Packaging designation differs (bulk versus standard). All other electrical and mechanical parameters are identical.

Q: Are there any approval agency differences between substitute options?

A: ABC series substitutes (BK/ABC-V-25-R and ABC-V-25-R) carry CSA and UL approvals, matching the original BK/ABC-V-25 certifications. GBB series substitutes (BK/GBB-V-25-R and GBB-V-25-R) carry CSA and UR approvals. System requirements should determine which certification is appropriate.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status does not alter electrical or mechanical performance. All substitute parts are ROHS3 compliant, addressing environmental and regulatory requirements. The original BK/ABC-V-25 is RoHS non-compliant.

Q: Can these fuses be used interchangeably in the same circuit?

A: Yes, provided the circuit design accommodates the specified breaking capacity. All substitute parts maintain identical current ratings, voltage ratings, response time, and form factor. Breaking capacity variations (1kA AC for original versus 200A-10kA for substitutes) should be verified against circuit protection requirements.
