Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the ABC-V-30-R is based on the following allowed parameters:

Mandatory Match Criteria:

• Current Rating: 30 A (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)

Acceptable Variation Criteria:

• Voltage Rating - AC: Substitute must be rated for 125 V AC or higher
• Voltage Rating - DC: Substitute must be rated for 125 V DC or higher
• Approval Agency: Substitute must hold certifications equal to or exceeding CSA and UR

The substitute part 0324030.MXP (Littelfuse 324 Series) meets all mandatory match criteria and exceeds voltage and certification requirements, making it a valid equivalent for applications requiring higher AC voltage rating (250 V AC) or additional regulatory approvals.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (ABC-V-30-R): Select the ABC-V-30-R when the application requires CSA and UR certifications specifically, operates exclusively at 125 V AC or lower, and when Eaton supply chain preference is established.

Substitute Part Selection (0324030.MXP): Select the 0324030.MXP when the application operates at 250 V AC or lower, requires UL certification in addition to CSA/UR compliance, or when higher inventory availability is required for production volume. The substitute part is suitable for applications with operating temperatures between -55°C and 125°C.

Compatibility Constraints: Both parts are mechanically and electrically compatible within their respective voltage and certification domains. The substitute part's higher AC voltage rating (250 V) and expanded certification portfolio (CE, K-MARK, PSE, UL) make it suitable for international applications and higher-voltage circuit designs. The lower DC cold resistance of the substitute part (0.00182 Ohms versus 0.002225 Ohms) results in marginally lower voltage drop under DC operation.

Frequently Asked Questions (FAQ)

Q: Can the 0324030.MXP replace the ABC-V-30-R in a 125 V AC circuit?

A: Yes. The 0324030.MXP is rated for 250 V AC and 125 V DC, which exceeds the ABC-V-30-R requirements of 125 V AC and 125 V DC. Both parts are 30 A ceramic cartridge fuses with identical package dimensions (3AB, 3AG, 1/4" x 1-1/4" Axial) and fast-blow response characteristics.

Q: What is the difference in breaking capacity between these two fuses?

A: The ABC-V-30-R has a breaking capacity of 200 A AC and 1 kA DC at rated voltage. The 0324030.MXP has a breaking capacity of 100 A AC and 400 A DC at rated voltage. For applications requiring the higher AC breaking capacity of 200 A, the ABC-V-30-R is the appropriate selection.

Q: Are both fuses RoHS compliant?

A: Yes. Both the ABC-V-30-R and 0324030.MXP are ROHS3 compliant.

Q: Which certifications does each fuse hold?

A: The ABC-V-30-R holds CSA and UR certifications. The 0324030.MXP holds CE, K-MARK, PSE, and UL certifications. For applications requiring specific regional certifications, verify that the selected part meets the applicable regulatory requirements.

Q: What is the operating temperature range for each fuse?

A: The ABC-V-30-R does not specify an operating temperature range in the provided data. The 0324030.MXP operates between -55°C and 125°C.

Q: Can these fuses be used interchangeably in the same fuse holder?

A: Yes, both fuses use identical package dimensions (3AB, 3AG, 1/4" x 1-1/4" Axial) and are designed for through-hole mounting. They are mechanically interchangeable in standard fuse holders rated for these package types.

Q: What is the difference in melting I²t values?

A: The ABC-V-30-R has a melting I²t of 1429, while the 0324030.MXP has a melting I²t of 2490. The higher I²t value of the substitute part indicates a longer time-to-melt characteristic under overcurrent conditions, which may affect circuit protection response in applications with specific I²t requirements.
