Parameter Comparison

Engineering Selection Recommendations

All three parts—0230.375HXSP, 0230.375HXP, and 0230.375MXP—are active products manufactured by Littelfuse Inc. with identical electrical specifications, mechanical dimensions, and regulatory certifications. Selection among these equivalents may be based on inventory availability and procurement lead times, as all parts satisfy the same circuit protection requirements and compliance standards (CE, CSA, UL, ROHS3, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can 0230.375HXP and 0230.375MXP be used interchangeably with 0230.375HXSP?

A: Yes. All three parts are parametric equivalents with identical current ratings (375 mA), voltage ratings (250 V AC / 125 V DC), response characteristics (slow blow), mechanical dimensions (0.177" Dia x 0.571" L), breaking capacity (35A AC, 10kA DC), and regulatory approvals (CE, CSA, UL). They are direct functional substitutes.

Q: What determines substitutability for this fuse cartridge?

A: Substitutability is determined by exact matching of current rating, AC and DC voltage ratings, response time classification, physical dimensions, breaking capacity, melting I²t value, and regulatory approval status. All substitute parts listed meet these criteria.

Q: Are there any differences in performance between the substitute parts?

A: No. The substitute parts share identical electrical performance parameters, including DC cold resistance (1.1685 Ohms), melting I²t (0.58), and operating temperature range (-55°C ~ 125°C).

Q: Do all substitute parts have the same regulatory compliance?

A: Yes. All parts carry CE, CSA, and UL approvals, are ROHS3 compliant, and have REACH Unaffected status.

Q: What is the significance of the non-standard axial cartridge package?

A: The non-standard axial cartridge package defines the mechanical form factor and mounting orientation. All substitute parts use this identical package configuration, ensuring compatibility with existing through-hole mounting designs.
