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

Part Overview

The ABC-V-2-R is a 2 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 through-hole mounting in 3AB/3AG package format with dimensions of 1/4" x 1-1/4" (6.76mm x 32.82mm). The part maintains active product status and is RoHS3 compliant.

Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional characteristics align with the original specification, enabling direct replacement in circuit protection applications without design modification.

Substitute Part Grouping Explanation

Substitute parts for the ABC-V-2-R are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires:

Electrical Parameters (Must Match Exactly):

• Current Rating: 2 A
• Voltage Rating AC: 250 V
• Voltage Rating DC: 125 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 100A AC, 10kA DC

Mechanical Parameters (Must Match Exactly):

• Fuse Type: Cartridge, Ceramic
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial)
• Mounting Type: Through Hole

Compliance Parameters (Must Match or Exceed):

• Approval Agency: CSA, UL minimum
• RoHS Status: ROHS3 Compliant

Parts meeting all these criteria are classified as direct substitutes and can be used interchangeably in circuit protection applications without circuit redesign or performance degradation.

Engineering Selection Recommendations

The Littelfuse 0324002.HXP is a direct electrical and mechanical substitute for the Eaton ABC-V-2-R ceramic cartridge fuse. Both parts satisfy identical current, voltage, and breaking capacity requirements for 2 A, 250 V AC / 125 V DC circuit protection applications.

Compliance Alignment: Both parts maintain RoHS3 compliance and active product status. The Littelfuse substitute carries additional regulatory approvals (CE, PSE) beyond the minimum CSA and UL requirements of the original part, providing expanded market compatibility.

Physical Compatibility: Dimensional variations between the two parts (diameter 0.266" vs. 0.275", length 1.292" vs. 1.288") remain within standard mechanical tolerances for 3AB/3AG cartridge fuse specifications and do not affect through-hole mounting compatibility.

Performance Characteristics: While DC cold resistance and melting I²t values differ between manufacturers, both parts are specified for identical fast-blow response time and breaking capacity. These differences reflect manufacturing process variations and do not impact functional equivalence in circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0324002.HXP replace the Eaton ABC-V-2-R in existing designs?

A: Yes. Both parts meet identical electrical specifications (2 A, 250 V AC, 125 V DC, fast-blow response, 100A AC / 10kA DC breaking capacity) and share the same 3AB/3AG cartridge package format. Direct substitution is supported without circuit modification.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The Littelfuse part measures 0.275" diameter versus 0.266" for the Eaton part, and 1.288" length versus 1.292". These differences fall within standard mechanical tolerances for 3AB/3AG cartridge fuses and do not affect through-hole mounting compatibility.

Q: Do both parts carry the same regulatory approvals?

A: The Littelfuse substitute carries additional approvals (CE, PSE) beyond the CSA and UL certifications required for the original Eaton part. Both parts maintain RoHS3 compliance.

Q: What is the significance of the different melting I²t and DC cold resistance values?

A: These parameters reflect manufacturing process differences between Eaton and Littelfuse but do not affect functional equivalence. Both parts are specified for identical fast-blow response time and breaking capacity at rated voltage.

Q: Are both parts currently available?

A: Both parts maintain active product status. Inventory availability should be confirmed with the respective manufacturers or authorized distributors.

Q: Can these parts be used interchangeably in mixed-manufacturer applications?

A: Yes. Electrical and mechanical equivalence permits interchangeable use. However, design documentation should be updated to reflect any manufacturer change for traceability and future maintenance purposes.
