Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABC-6-R is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Current Rating: 6 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Response Time: Fast Blow (exact match required)

Mechanical Compatibility Requirements:

• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Mounting Type: Requires Holder (exact match required)

Regulatory & Compliance Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Product Status: Active (minimum requirement)

All substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the ABC-6-R in applications requiring 6 A ceramic cartridge fuse protection at 250 V AC / 125 V DC.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct interchangeability with the ABC-6-R. Selection among equivalent options is based on the following factors:

Direct Manufacturer Equivalent: BK/ABC-6-R is the direct equivalent from Eaton - Electronics Division, offering identical electrical characteristics, breaking capacity, and melting I²t specifications. This part carries the same CSA and UL approvals as the ABC-6-R.

Eaton GBB Series Alternatives: BK/GBB-6-R and GBB-6-R are parametric equivalents from Eaton's GBB series. Both maintain identical voltage and current ratings with matching fast-blow response. The GBB-6-R provides equivalent breaking capacity (200 A AC / 10 kA DC) to the ABC-6-R. Both carry CSA and UR certifications. The lower DC cold resistance (0.018 Ohms versus 0.021 Ohms) represents a minor operational difference with no impact on circuit protection function.

Littelfuse 314 Series Alternatives: 0314006.HXP, 0314006.MXP, and 0314006.VXP are parametric equivalents from Littelfuse Inc.'s 314 series. All three maintain identical voltage and current ratings with matching fast-blow response and 10 kA DC breaking capacity. These parts carry expanded approval certifications including CE, CSA, K-MARK, PSE, and UL. The higher AC breaking capacity (750 A) and broader operating temperature range (-55°C to 125°C) provide enhanced performance margins. Melting I²t is specified at 45 (compared to 58 for ABC-6-R), indicating slightly faster thermal response.

All substitute parts are ROHS3 compliant and active in production status.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-6-R be used as a direct replacement for ABC-6-R?

A: Yes. BK/ABC-6-R is the direct manufacturer equivalent from Eaton - Electronics Division with identical electrical ratings (6 A, 250 V AC, 125 V DC), response time (fast blow), mechanical dimensions (1/4" x 1-1/4"), and approval certifications (CSA, UL). It is a direct functional substitute.

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

A: Both ABC and GBB series fuses meet the specified 6 A, 250 V AC, 125 V DC requirements with identical mechanical packaging and fast-blow response. The GBB series has a lower DC cold resistance (0.018 Ohms versus 0.021 Ohms). GBB-6-R provides the same 200 A AC / 10 kA DC breaking capacity as ABC-6-R. Both series carry CSA certification; GBB carries UR certification instead of UL.

Q: Are Littelfuse 314 series fuses compatible with the ABC-6-R?

A: Yes. The Littelfuse 314 series parts (0314006.HXP, 0314006.MXP, 0314006.VXP) are parametric equivalents with identical electrical ratings (6 A, 250 V AC, 125 V DC), response time (fast blow), and mechanical dimensions (1/4" x 1-1/4"). All fit standard 3AB and 3AG holders. These parts carry broader international certifications (CE, CSA, K-MARK, PSE, UL) and operate across a wider temperature range (-55°C to 125°C).

Q: What is the significance of the different melting I²t values?

A: Melting I²t indicates the thermal energy required to melt the fuse element. ABC-6-R specifies 58, while Littelfuse 314 series parts specify 45. A lower I²t value indicates faster thermal response to overcurrent conditions. Both values are within the acceptable range for 6 A fast-blow ceramic cartridge fuses and do not affect basic circuit protection function.

Q: Do all substitute parts fit the same holder as ABC-6-R?

A: Yes. All substitute parts are specified for 3AB and 3AG holders with identical mechanical dimensions of 1/4" diameter x 1-1/4" length (6.35 mm x 31.75 mm). They are mechanically interchangeable in any holder designed for these standard cartridge fuse sizes.

Q: What is the difference in breaking capacity between ABC-6-R and the Littelfuse alternatives?

A: ABC-6-R is rated for 200 A AC and 10 kA DC breaking capacity. Littelfuse 314 series parts are rated for 750 A AC and 10 kA DC breaking capacity. The higher AC breaking capacity in Littelfuse parts provides additional margin for fault current interruption but does not affect normal circuit operation at rated current.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including ABC-6-R, BK/ABC-6-R, GBB series, and Littelfuse 314 series, are ROHS3 compliant and suitable for applications requiring restricted substance compliance.

Q: Which substitute part has the broadest international certification?

A: The Littelfuse 314 series parts carry the most comprehensive certification portfolio: CE, CSA, K-MARK, PSE, and UL. This makes them suitable for applications requiring compliance with multiple international standards. ABC and GBB series parts carry CSA and UL (or UR) certifications, which are appropriate for North American applications.
