Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABC-V-3/4-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 750 mA
• 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
• Breaking Capacity @ Rated Voltage: 35A AC, 10kA DC

The substitute part 0324.750HXP manufactured by Littelfuse Inc. meets all mandatory matching parameters and is therefore classified as a direct equivalent. Both parts share identical electrical ratings, mechanical package specifications, and breaking capacity ratings, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ABC-V-3/4-R and 0324.750HXP are active production parts with full RoHS3 compliance. The Littelfuse 0324.750HXP substitute carries additional CE approval certification in addition to CSA and UL approvals, providing broader regulatory coverage for international applications. Both parts are manufactured to identical electrical and mechanical specifications for the 750 mA, 250 V AC / 125 V DC fast-blow ceramic cartridge fuse category.

Selection between these parts should be based on supply availability, lead time requirements, and regional regulatory requirements. The Littelfuse part offers enhanced international compliance documentation through CE certification. Dimensional tolerances between the two parts are within acceptable through-hole mounting specifications, with both conforming to the 3AB/3AG standard package format.

Frequently Asked Questions (FAQ)

Q: Can the 0324.750HXP directly replace the ABC-V-3/4-R in existing circuit designs?

A: Yes. Both parts share identical current ratings (750 mA), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package format (3AB/3AG), and breaking capacity (35A AC / 10kA DC). The parts are mechanically and electrically interchangeable for through-hole mounting applications.

Q: What are the dimensional differences between these two parts?

A: The ABC-V-3/4-R measures 0.266" diameter × 1.292" length (6.76mm × 32.82mm). The 0324.750HXP measures 0.275" diameter × 1.288" length (6.99mm × 32.72mm). Both dimensions fall within the 3AB/3AG standard specification tolerance and are compatible with standard through-hole fuse holders designed for this package format.

Q: Are there differences in DC cold resistance between these parts?

A: The ABC-V-3/4-R has a DC cold resistance of 0.3 Ohms, while the 0324.750HXP has 0.25 Ohms. This difference does not affect substitution eligibility, as both values are within acceptable operating parameters for this fuse category and do not impact circuit protection performance.

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

A: The ABC-V-3/4-R has a Melting I²t of 0.145, while the 0324.750HXP has 0.466. Both parts are rated for identical current and voltage specifications and breaking capacity. The I²t value represents thermal energy absorption characteristics; both parts meet the fast-blow response time classification and are suitable for the same circuit protection applications.

Q: Which part has broader regulatory approvals?

A: The 0324.750HXP carries CE, CSA, and UL approvals, while the ABC-V-3/4-R carries CSA and UL approvals. For applications requiring CE certification for European markets, the Littelfuse part provides additional compliance documentation.

Q: Are both parts currently available?

A: Yes. The ABC-V-3/4-R has 939 units in stock, and the 0324.750HXP has 845 units in stock. Both are active production parts.
