Equivalent & Substitute Parts for ABC-4-R Ceramic Cartridge Fuse

Part Overview

The ABC-4-R is a 4 A ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated for 250 V AC and 125 V DC operation. This fast-blow fuse is designed for use with 3AB and 3AG holders and features a breaking capacity of 200 A AC and 10 kA DC. The part maintains Active product status with 913 units currently in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same fuse category, voltage ratings, current ratings, and physical package dimensions. Alternative sources and series variants are documented to support component procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on substitution relationship type:

Direct Manufacturer Substitutes (Same Manufacturer - Eaton) These parts share identical electrical and mechanical specifications with the ABC-4-R. They are sourced from the same manufacturer and maintain full compatibility:

• BK/ABC-4-R: Identical specifications with higher inventory availability (5025 units)
• BK/GBB-4-R: GBB series variant with identical electrical parameters
• GBB-4-R: GBB series variant with full parameter equivalence

Parametric Equivalents (Alternative Manufacturers) These parts maintain the critical electrical and mechanical parameters required for direct substitution:

• 0314004.HXP (Littelfuse): Ceramic cartridge fuse, 4 A, 250 V AC, 125 V DC, 3AB/3AG package
• 0314004.VXP (Littelfuse Inc.): Ceramic cartridge fuse, 4 A, 250 V AC, 125 V DC, 3AB/3AG package

Non-Equivalent Alternative (Different Fuse Type)

• 0001.1030 (SCHURTER Inc.): Glass cartridge fuse with reduced breaking capacity (1.5 kA) and obsolete status. Not recommended for direct substitution due to fuse type difference and product discontinuation.

Substitution eligibility is determined by matching: current rating (4 A), AC voltage rating (250 V), DC voltage rating (125 V), fuse type (ceramic cartridge), response time (fast blow), and physical package (3AB/3AG, 1/4" x 1-1/4").

Parameter Comparison

Engineering Selection Recommendations

Recommended Direct Substitutes

BK/ABC-4-R and GBB-4-R are the primary recommended substitutes. Both maintain Active product status, full electrical equivalence, and identical physical package specifications. BK/ABC-4-R offers the highest inventory availability (5025 units) and identical breaking capacity specifications. GBB-4-R provides an alternative from the same manufacturer with equivalent performance characteristics.

Alternative Manufacturer Substitutes

0314004.HXP and 0314004.VXP (Littelfuse Series 314) are parametrically equivalent ceramic cartridge fuses meeting all critical electrical and mechanical requirements. Both parts are Active status with comprehensive international approvals (CE, CSA, K-MARK, PSE, UL). These parts feature higher breaking capacity on AC (750 A) compared to the ABC-4-R (200 A), providing enhanced protection margin. Operating temperature range extends to -55°C to 125°C, exceeding the ABC-4-R specification. Both Littelfuse variants are ROHS3 compliant and REACH unaffected.

Non-Recommended Alternative

0001.1030 (SCHURTER glass cartridge fuse) is not recommended for direct substitution. This part differs in fuse type (glass versus ceramic), carries Obsolete product status, and features significantly reduced breaking capacity (1.5 kA AC versus 200 A AC for ABC-4-R). The glass construction and lower breaking capacity indicate this part is designed for different circuit protection requirements.

Compliance Considerations

All recommended substitutes maintain ROHS3 compliance and appropriate international certifications. Littelfuse variants provide expanded approval agency coverage (CE, CSA, K-MARK, PSE, UL) compared to the ABC-4-R (CSA, UL).

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-4-R be used as a direct replacement for ABC-4-R?

A: Yes. BK/ABC-4-R is manufactured by Eaton and maintains identical electrical specifications (4 A, 250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and physical package (3AB/3AG, 1/4" x 1-1/4"). Both parts are Active status with CSA and UL approvals.

Q: What is the difference between ABC-4-R and GBB-4-R?

A: Both are Eaton ceramic cartridge fuses with identical electrical ratings (4 A, 250 V AC, 125 V DC) and physical dimensions. The primary difference is the series designation (ABC versus GBB). Both are Active status and fully compatible with 3AB/3AG holders.

Q: Are Littelfuse 0314004.HXP and 0314004.VXP suitable replacements?

A: Yes. Both Littelfuse parts are parametrically equivalent ceramic cartridge fuses with matching current (4 A), voltage ratings (250 V AC, 125 V DC), fuse type, response time, and package specifications. Both are Active status. The Littelfuse variants feature higher AC breaking capacity (750 A) and extended operating temperature range (-55°C to 125°C).

Q: Why is SCHURTER 0001.1030 not recommended?

A: The SCHURTER part is a glass cartridge fuse, not ceramic. It has significantly lower breaking capacity (1.5 kA AC versus 200 A AC) and is marked Obsolete. These differences indicate it is designed for different circuit protection applications and should not be used as a direct substitute.

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

A: Yes. All recommended substitute parts maintain the 3AB/3AG package specification with physical dimensions of 0.250" Dia x 1.250" L (6.35mm x 31.75mm), ensuring mechanical compatibility with existing holders.

Q: What certifications do the substitute parts carry?

A: ABC-4-R and direct Eaton substitutes carry CSA and UL approvals. Littelfuse variants (0314004.HXP and 0314004.VXP) carry expanded certifications: CE, CSA, K-MARK, PSE, and UL. All recommended parts are ROHS3 compliant.

Q: Which substitute offers the best inventory availability?

A: BK/ABC-4-R offers the highest inventory with 5025 units in stock, compared to 913 units for the original ABC-4-R. This variant provides identical specifications with improved supply availability.
