Equivalent & Substitute Parts for ABC-2-R Ceramic Fuse Cartridge

Part Overview

The ABC-2-R is a 2 A ceramic fuse cartridge rated for 250 V AC and 125 V DC operation, manufactured by Eaton - Electronics Division. This fast-blow cartridge fuse requires a compatible holder (3AB, 3AG format) and is designed for circuit protection in industrial and commercial applications. The part maintains Active product status with 641 pieces currently in stock.

Substitute parts are identified based on matching electrical specifications, mechanical compatibility, and approval certifications. Alternative sources provide equivalent performance characteristics while maintaining the same form factor and functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Current Rating: 2 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:

• 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)
• Fuse Type: Cartridge, Ceramic (exact match required)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Approval Agency: CSA and/or UL certification (minimum requirement)

All identified substitute parts meet these criteria and are classified as parametric equivalents suitable for direct replacement in applications requiring the ABC-2-R specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - BK/ABC-2-R (Eaton - Electronics Division): This part is the direct manufacturer equivalent from Eaton. It maintains identical electrical and mechanical specifications to the ABC-2-R, with matching breaking capacity (100A AC, 10kA DC) and CSA/UL certifications. Current inventory of 1595 pieces supports immediate availability.

Secondary Selection - 0314002.HXP, 0314002.MXP, 0314002.VXP (Littelfuse Inc.): These Littelfuse Series 314 ceramic fuse cartridges meet all critical electrical and mechanical parameters. All three variants carry expanded approval certifications (CE, CSA, PSE, UL) and support extended operating temperature range (-55°C to 125°C). Littelfuse parts feature higher melting I²t value (11 versus 2.167) and lower DC cold resistance (0.07 Ohms versus 0.089 Ohms). Inventory availability ranges from 961 to 1872 pieces across the three variants.

Alternative Selection - BK/GBB-2-R (Eaton - Electronics Division): This Eaton GBB series part matches all critical electrical specifications and mechanical form factor. Breaking capacity specification differs (10kA versus 100A AC, 10kA DC for the main part). CSA and UR certifications are provided. Inventory of 1721 pieces is available.

All substitute parts are Active status products with ROHS3 compliance and REACH Unaffected designation.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-2-R be used as a direct replacement for ABC-2-R?

A: Yes. BK/ABC-2-R is the direct manufacturer equivalent from Eaton - Electronics Division. All electrical ratings (2 A, 250 V AC, 125 V DC), mechanical dimensions (0.250" Dia x 1.250" L), package format (3AB, 3AG), and approval certifications (CSA, UL) are identical. This is the recommended substitute when ABC-2-R is unavailable.

Q: What is the difference between Eaton and Littelfuse ceramic fuse cartridges in this specification?

A: Both manufacturers provide 2 A, 250 V AC, 125 V DC ceramic cartridge fuses in the 3AB/3AG package with fast-blow response. Littelfuse Series 314 parts (0314002.HXP, 0314002.MXP, 0314002.VXP) offer expanded certifications (CE, PSE in addition to CSA, UL) and extended operating temperature range (-55°C to 125°C). Littelfuse parts have higher melting I²t (11 versus 2.167) and lower DC cold resistance (0.07 Ohms versus 0.089 Ohms). Both are suitable for direct replacement based on electrical and mechanical equivalence.

Q: Are all substitute parts compatible with existing 3AB/3AG fuse holders?

A: Yes. All substitute parts maintain the identical mechanical specification: 0.250" diameter by 1.250" length (6.35mm x 31.75mm). They are designed for 3AB and 3AG holder formats and are mechanically interchangeable with the ABC-2-R.

Q: What certifications do the substitute parts carry?

A: BK/ABC-2-R carries CSA and UL certifications. BK/GBB-2-R carries CSA and UR certifications. Littelfuse parts (0314002.HXP, 0314002.MXP, 0314002.VXP) carry CE, CSA, PSE, and UL certifications. All parts meet ROHS3 compliance requirements.

Q: Can I use BK/GBB-2-R if the breaking capacity specification is different?

A: BK/GBB-2-R specifies 10kA breaking capacity, while ABC-2-R specifies 100A AC and 10kA DC. This difference in breaking capacity specification should be evaluated against your circuit protection requirements. If 100A AC breaking capacity is required, use BK/ABC-2-R or Littelfuse alternatives instead.

Q: What is the difference between 0314002.HXP, 0314002.MXP, and 0314002.VXP?

A: All three Littelfuse variants share identical electrical specifications (2 A, 250 V AC, 125 V DC), mechanical dimensions, response time (fast blow), and certifications. The part number suffix (.HXP, .MXP, .VXP) indicates different internal construction or material variants within the Series 314 line. All three are parametric equivalents suitable for direct replacement.

Q: Are these fuses RoHS compliant?

A: Yes. All listed parts (ABC-2-R, BK/ABC-2-R, BK/GBB-2-R, and all Littelfuse variants) are ROHS3 Compliant and REACH Unaffected.
