Frequently Asked Questions (FAQ)

Q: Can the 0375012.HXP be used as a direct replacement for the 0375012.MXP?

A: Yes. Both parts are identical in all electrical and mechanical parameters, including current rating (12 A), voltage rating (125 V AC), fuse type (cartridge, glass), response time (slow blow), package form factor (3AB, 3AG, 1/4" x 1-1/4" axial), mounting type (through hole), breaking capacity (10 kA), and regulatory approvals (CE, CSA, UL).

Q: What are the key parameters that determine substitution eligibility for this fuse?

A: Substitution eligibility is determined by exact matching of: current rating (12 A), AC voltage rating (125 V), fuse type (cartridge, glass), response time (slow blow), package designation (3AB, 3AG, 1/4" x 1-1/4" axial), mounting type (through hole), breaking capacity (10 kA), and regulatory certifications (CE, CSA, UL).

Q: Are there any differences in compliance or certification between these parts?

A: No. Both the 0375012.MXP and 0375012.HXP carry identical regulatory approvals (CE, CSA, UL) and RoHS compliance status (ROHS3 Compliant).

Q: What is the physical form factor of these fuses?

A: Both parts use the 3AB/3AG cartridge form factor with dimensions of 0.275" diameter x 1.288" length (6.99 mm x 32.72 mm). This is a standard through-hole axial configuration.

Q: What is the breaking capacity of these fuses?

A: Both parts have a breaking capacity of 10 kA at the rated voltage of 125 V AC.
