Equivalent & Substitute Parts for BK/ABC-6 Ceramic Fuse Cartridge

Part Overview

The BK/ABC-6 is a 6 A ceramic fuse cartridge rated for 250 V AC and 125 V DC operation, designed for use with 3AB, 3AG holder configurations in 1/4" x 1-1/4" form factor. Manufactured by Eaton - Electronics Division, this component is classified as obsolete product status. Due to obsolescence, equivalent and substitute parts from active product lines are available to maintain circuit protection functionality in applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete BK/ABC-6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 6 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"
• Size / Dimension: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)
• Mounting Type: Requires Holder

All substitute parts listed maintain these parameters without deviation. Variations in secondary characteristics such as melting I²t, DC cold resistance, breaking capacity specifications, and RoHS compliance status do not affect functional substitutability for the primary circuit protection application.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Eaton Active Series:

The ABC-6-R, BK/ABC-6-R, and BK/ABC-6NN-R represent direct active product line equivalents from Eaton - Electronics Division. These parts maintain identical electrical and mechanical specifications to the obsolete BK/ABC-6 while offering ROHS3 compliance. Selection from this group ensures continuity within the same manufacturer ecosystem and certification framework (CSA, UL).

Secondary Recommendation - Eaton GBB Series:

The BK/GBB-6-R and GBB-6-R are parametric equivalents from Eaton's GBB series. These parts satisfy all mandatory substitution criteria and provide ROHS3 compliance. Certification includes CSA and UR approvals, providing alternative regulatory coverage.

Cross-Manufacturer Alternative - Littelfuse 314 Series:

The 0314006.HXP, 0314006.MXP, and 0314006.VXP from Littelfuse Inc. are parametric equivalents meeting all electrical and mechanical requirements. These parts offer expanded approval agency coverage (CE, CSA, K-MARK, PSE, UL for HXP and MXP; CE, CSA, KC, PSE, UL for VXP) and extended operating temperature range (-55°C to 125°C). Selection of Littelfuse alternatives is appropriate when cross-manufacturer sourcing is acceptable and expanded certifications are beneficial.

Product Status Consideration:

All substitute parts listed carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete BK/ABC-6.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the BK/ABC-6?

A: Yes. All listed substitute parts maintain identical current rating (6 A), voltage ratings (250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and physical dimensions (0.250" Dia x 1.250" L). They are mechanically and electrically compatible with existing 3AB and 3AG holder configurations.

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

A: Both series meet all mandatory electrical and mechanical parameters. The primary difference is series designation and approval agency coverage. ABC series maintains CSA and UL certifications identical to the original part. GBB series provides CSA and UR certifications. Selection depends on application-specific regulatory requirements.

Q: Why should I consider Littelfuse alternatives over Eaton products?

A: Littelfuse 314 series parts offer expanded approval agency coverage (including CE, K-MARK, PSE, KC) and extended operating temperature range (-55°C to 125°C versus unspecified for Eaton). These characteristics are beneficial for applications requiring broader international certifications or operation in temperature-extreme environments. Electrical and mechanical compatibility remains identical.

Q: Are there differences in melting I²t or DC cold resistance between substitutes?

A: Yes. Secondary characteristics such as melting I²t (ranging from 31.6 to 58) and DC cold resistance (ranging from 0.018 to 0.024 Ohms) vary among substitutes. These variations do not affect functional substitutability for standard circuit protection applications, as all parts meet the same current and voltage ratings. Application-specific thermal or resistance requirements should be evaluated independently.

Q: What does RoHS3 compliance mean for my application?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The original BK/ABC-6 is RoHS non-compliant. All active substitutes are ROHS3 compliant, making them suitable for applications subject to environmental and regulatory restrictions on hazardous substances.

Q: Can I mix different substitute part numbers in the same circuit or equipment?

A: All listed substitutes are parametrically equivalent and can be used in the same application. However, within a single circuit or equipment design, using parts from the same manufacturer and series is recommended for consistency in supply chain management and documentation purposes.

Q: What is the difference between bulk and other packaging options?

A: All substitute parts listed are supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance. Bulk packaging is standard for component-level procurement and does not impact substitutability.
