Equivalent & Substitute Parts for BK/ABC-6NN-R

Part Overview

The BK/ABC-6NN-R is a 6 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation, manufactured by Eaton - Electronics Division. This fast-blow fuse is designed for use with 3AB, 3AG holders and measures 0.250" diameter by 1.250" length. The part is currently active in production with 766 pieces in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers are preferred for supply chain diversification, or when equivalent performance specifications are required across different product series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/ABC-6NN-R is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

• Current Rating: 6 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed meet these critical parameters. Variations in secondary parameters such as breaking capacity, DC cold resistance, melting I²t, and approval agencies do not disqualify substitution when core electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status and full RoHS3 compliance. Selection among equivalent parts should be based on the following factors:

Eaton - Electronics Division Series (BK/ABC-6-R, BK/GBB-6-R, GBB-6-R): These parts maintain identical electrical specifications to the primary part and are manufactured by the same supplier. The BK/ABC-6-R offers the highest inventory availability at 1368 pieces and identical breaking capacity specifications. The GBB series variants provide alternative product lines within the same manufacturer portfolio.

Littelfuse Inc. Series (0314006.HXP, 0314006.MXP, 0314006.VXP): These parts provide cross-manufacturer equivalence with enhanced breaking capacity ratings (750A AC versus 200A AC for Eaton parts) and broader approval agency certifications including CE, K-MARK, KC, and PSE. Operating temperature range is specified as -55°C to 125°C. These parts are suitable for applications requiring expanded international compliance or higher breaking capacity margins.

All substitute parts are compatible with 3AB and 3AG fuse holders and maintain identical physical dimensions and fast-blow response characteristics.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-6NN-R be directly replaced with BK/ABC-6-R?

A: Yes. Both parts are identical in all critical electrical and mechanical parameters: 6 A current rating, 250 V AC / 125 V DC voltage ratings, fast-blow response, and 3AB/3AG package compatibility. The primary difference is the product designation suffix.

Q: What is the difference between Eaton and Littelfuse substitute options?

A: Eaton parts (BK/ABC-6-R, BK/GBB-6-R, GBB-6-R) maintain identical breaking capacity specifications to the original part. Littelfuse parts (0314006.HXP, 0314006.MXP, 0314006.VXP) provide higher breaking capacity at 750A AC and broader international certifications. All meet the core 6 A, 250 V AC, 125 V DC requirements.

Q: Are all substitute parts compatible with existing fuse holders?

A: Yes. All substitute parts are specified for 3AB and 3AG holders with identical physical dimensions of 0.250" diameter by 1.250" length. No holder modifications are required.

Q: What is the significance of the different approval agencies listed?

A: Approval agencies indicate regulatory compliance for specific markets. CSA and UL certifications are standard for North American applications. Littelfuse parts include additional certifications (CE, K-MARK, KC, PSE) for European and Asian market compliance. Selection should align with the intended geographic application.

Q: Do DC cold resistance variations affect substitution eligibility?

A: DC cold resistance values (ranging from 0.018 to 0.024 Ohms across all parts) are secondary parameters that do not disqualify substitution. All values remain within acceptable ranges for the 6 A fast-blow cartridge fuse category and do not affect core circuit protection function.

Q: Can melting I²t differences impact circuit protection performance?

A: Melting I²t values (58 for Eaton parts, 45 for Littelfuse parts) represent thermal energy characteristics. Both values are within acceptable ranges for 6 A fast-blow fuses. Substitution is valid based on identical current rating, voltage rating, and response time specifications.
