Substitute Part Grouping Explanation

Substitution for the 0375015.M is determined by strict equivalence across the following critical parameters:

• Current Rating: 15 A (exact match required)
• Voltage Rating: 125 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Breaking Capacity: 10kA (exact match required)
• Physical Dimensions: 0.275" Dia x 1.288" L (exact match required)

All substitute parts listed maintain identical electrical and mechanical specifications. Substitution is valid based on these parameters alone.

Parameter Comparison

Engineering Selection Recommendations

Both 0375015.MXP and 0375015.HXP are direct functional equivalents to the obsolete 0375015.M. Selection between these two active alternatives should be based on the following factors:

0375015.MXP and 0375015.HXP are both ROHS3 compliant and carry identical electrical and mechanical specifications. The primary distinction is product availability and packaging designation. Both parts maintain full CE, CSA, and UL certifications required for regulated applications.

For new designs or system replacements, either substitute part is suitable. The choice between 0375015.MXP and 0375015.HXP should be determined by supply chain availability and internal procurement specifications, as both meet all technical and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can 0375015.MXP or 0375015.HXP be used as direct replacements for 0375015.M?

A: Yes. Both parts are electrically and mechanically identical to the main part across all critical parameters: 15A current rating, 125V AC voltage rating, slow-blow response, 3AB/3AG package format, and 10kA breaking capacity. Physical dimensions and mounting type are identical.

Q: What is the difference between 0375015.MXP and 0375015.HXP?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The designation difference reflects internal Littelfuse product categorization. Both are ROHS3 compliant and carry the same certifications.

Q: Why is the main part 0375015.M listed as obsolete?

A: The 0375015.M is classified as obsolete in the product lifecycle. However, direct functional equivalents in active status are available, ensuring continued availability for replacement and maintenance applications.

Q: Are there any compliance differences between the main part and substitutes?

A: Yes. The main part 0375015.M is RoHS non-compliant, while both substitute parts (0375015.MXP and 0375015.HXP) are ROHS3 compliant. All three parts maintain CE, CSA, and UL certifications.

Q: Can these fuses be used interchangeably in existing circuit designs?

A: Yes, provided the circuit board layout and mechanical mounting accommodate the 3AB/3AG package format with 0.275" diameter and 1.288" length dimensions. All three parts share identical physical specifications.

Q: What is the breaking capacity specification?

A: All three parts have a breaking capacity of 10kA at the rated voltage of 125V AC, meeting standard fuse performance requirements for this current and voltage class.
