Equivalent & Substitute Parts for ABC-V-5-R

Part Overview

The ABC-V-5-R is a 5 A ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated for 250 V AC and 125 V DC operation. This through-hole mounted fuse is designed for fast-blow response applications and is classified as an active product. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the specified parameter ranges for 3AB, 3AG form factor ceramic fuses.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABC-V-5-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 5 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" (Axial)
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

All identified substitute parts meet these mandatory criteria. Variations in secondary parameters such as breaking capacity, melting I²t, operating temperature range, and DC cold resistance do not preclude substitution when the primary electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are active products with ROHS3 compliance and appropriate regulatory approvals. Selection between the ABC-V-5-R and its substitutes should be based on the following criteria:

Eaton ABC-V-5-R and BK/ABC-V-5-R: These parts are direct equivalents from the same manufacturer. The BK/ABC-V-5-R designation represents an alternative packaging or distribution variant of the same fuse. Both carry CSA and UL approvals and are suitable for applications requiring Eaton-sourced components.

Littelfuse 0324005.HXP and 0324005.MXP: These parts provide cross-manufacturer substitution with expanded regulatory approvals including CE, K-MARK, and PSE certifications in addition to CSA and UL. The Littelfuse variants feature higher AC breaking capacity (750 A versus 200 A) and specified operating temperature range (-55°C to 125°C). The 0324005.MXP variant has significantly higher inventory availability (5038 pieces) compared to other options.

All substitute parts maintain electrical equivalence at the rated 5 A, 250 V AC, 125 V DC specification and are mechanically compatible with 3AB, 3AG through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the BK/ABC-V-5-R be used as a direct replacement for the ABC-V-5-R?

A: Yes. The BK/ABC-V-5-R is manufactured by Eaton - Electronics Division and shares identical electrical ratings (5 A, 250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and package specification (3AB, 3AG, 1/4" x 1-1/4" axial). Both parts are active products with ROHS3 compliance and CSA/UL approvals.

Q: Are the Littelfuse 0324005.HXP and 0324005.MXP parts fully compatible with the ABC-V-5-R?

A: Yes. Both Littelfuse parts meet all mandatory substitution criteria: 5 A current rating, 250 V AC and 125 V DC voltage ratings, ceramic cartridge fuse type, fast-blow response, and 3AB, 3AG package specification. Both are through-hole mounted, ROHS3 compliant, and carry CSA and UL approvals. The Littelfuse variants include additional certifications (CE, K-MARK, PSE) and specified operating temperature range (-55°C to 125°C).

Q: What is the difference between the 0324005.HXP and 0324005.MXP?

A: Both parts are electrically and mechanically identical. They share the same current rating, voltage ratings, fuse type, response time, package specification, and regulatory approvals. The primary difference is inventory availability, with 0324005.MXP having 5038 pieces in stock compared to 1010 pieces for 0324005.HXP.

Q: Do the differences in breaking capacity affect substitution suitability?

A: Breaking capacity is a secondary parameter that does not preclude substitution when primary electrical and mechanical specifications are identical. The ABC-V-5-R and BK/ABC-V-5-R specify 200 A AC breaking capacity, while the Littelfuse variants specify 750 A AC breaking capacity. All parts maintain 10 kA DC breaking capacity. Higher breaking capacity does not create incompatibility in applications designed for the lower specification.

Q: Are there differences in melting I²t between the parts?

A: Yes. The Eaton ABC-V-5-R and BK/ABC-V-5-R specify melting I²t of 32.83, while the Littelfuse 0324005.HXP and 0324005.MXP specify melting I²t of 26. Both values fall within acceptable ranges for 5 A fast-blow ceramic cartridge fuses and do not preclude cross-manufacturer substitution when all primary electrical and mechanical parameters match.

Q: Can these fuses be used in applications requiring extended temperature operation?

A: The Littelfuse 0324005.HXP and 0324005.MXP specify an operating temperature range of -55°C to 125°C. The Eaton ABC-V-5-R and BK/ABC-V-5-R do not specify an operating temperature range in the provided data. For applications requiring confirmed temperature specifications, the Littelfuse variants provide documented operating range.

Q: What regulatory approvals apply to each part?

A: The Eaton ABC-V-5-R and BK/ABC-V-5-R carry CSA and UL approvals. The Littelfuse 0324005.HXP and 0324005.MXP carry CE, CSA, K-MARK, PSE, and UL approvals. All parts are ROHS3 compliant. Selection should be based on the specific regulatory requirements of the target application or market.
