Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/ABC-V-30 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 30 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
• Melting I²t: 1429

All substitute parts listed meet these mandatory parameters. Variations in breaking capacity, DC cold resistance, series designation, and RoHS compliance status are noted but do not prevent functional substitution when electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: BK/ABC-V-30-R

The BK/ABC-V-30-R is the direct successor to the obsolete BK/ABC-V-30. Both parts share identical electrical ratings, response characteristics, and DC cold resistance. The primary distinction is product status: BK/ABC-V-30-R is active and ROHS3 compliant, whereas the original part is obsolete and RoHS non-compliant. This part maintains the same series designation (ABC) and is the preferred choice for direct replacement in new procurement and system updates.

Secondary Recommendations: BK/ABC-BV-30-R, BK/GBB-BV-30-R, BK/GBB-V-30-R, GBB-V-30-R

All remaining substitute parts meet the mandatory electrical and mechanical parameters. These parts are active and ROHS3 compliant. Differences exist in series designation (GBB versus ABC) and breaking capacity specifications. Selection among these alternatives depends on application-specific breaking capacity requirements and circuit protection design criteria.

Compliance Consideration:

All substitute parts carry CSA and UL approvals, consistent with the original part's certification status. Parts designated with ROHS3 compliance are suitable for applications subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-V-30-R be used as a direct replacement for BK/ABC-V-30?

A: Yes. Both parts share identical current rating (30 A), voltage ratings (250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package format (3AB/3AG), and physical dimensions (0.266" Dia x 1.292" L). The primary difference is product status and RoHS compliance.

Q: What is the difference between ABC and GBB series fuses?

A: Both series meet the mandatory electrical and mechanical parameters specified for this application. The GBB series parts offer higher breaking capacity ratings in certain configurations (up to 10 kA for BK/GBB-V-30-R). Series selection should be based on circuit protection requirements and breaking capacity specifications for the target application.

Q: Are the GBB series parts compatible with existing through-hole mounting footprints designed for ABC series?

A: Yes. All substitute parts share identical package designation (3AB, 3AG) and physical dimensions (0.266" Dia x 1.292" L). Through-hole mounting compatibility is maintained across all listed substitutes.

Q: What does the "-R" suffix indicate in part numbers?

A: The "-R" suffix designates the active, current production version of the fuse. Parts without this suffix (such as the original BK/ABC-V-30) are obsolete.

Q: Does DC cold resistance variation affect substitution suitability?

A: DC cold resistance values are provided for reference. The original part specifies 0.002225 Ohms, while GBB series parts specify 0.00206 Ohms. Both values are within acceptable operating parameters for the 30 A, 250 V AC / 125 V DC rating. Application-specific circuit analysis should confirm acceptability in high-precision current-limiting applications.

Q: Which substitute part should be selected for new designs?

A: BK/ABC-V-30-R is recommended for new designs as the direct active successor to the obsolete BK/ABC-V-30. This part maintains series continuity and is ROHS3 compliant.
