Parameter Comparison

Engineering Selection Recommendations

Both 0375015.HXP and 0375015.MXP are direct functional equivalents to the obsolete 0375015.H. Selection between these two active substitutes is based on the following factors:

0375015.HXP: Packaged in bulk format with ROHS3 compliance and active product status. Inventory availability is 2046 units.

0375015.MXP: Packaged in bulk format with ROHS3 compliance, REACH unaffected status, and active product status. Inventory availability is 1934 units.

Both parts carry identical electrical specifications, mechanical dimensions, and regulatory certifications (CE, CSA, UL). The choice between them depends on supply chain requirements and regulatory documentation needs specific to your application region.

Frequently Asked Questions (FAQ)

Q: Can 0375015.HXP and 0375015.MXP be used interchangeably with 0375015.H?

A: Yes. Both substitute parts match all critical electrical parameters (15 A, 125 V AC, slow-blow response), mechanical dimensions (0.275" Dia x 1.288" L), package format (3AB, 3AG), and regulatory certifications (CE, CSA, UL) required for direct substitution.

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

A: Both parts are electrically and mechanically identical. The primary difference is that 0375015.MXP includes REACH unaffected status documentation, which may be required for certain regulatory jurisdictions. Both are ROHS3 compliant and actively manufactured.

Q: Why is the original 0375015.H classified as obsolete?

A: The 0375015.H is marked obsolete due to its RoHS non-compliant status. The substitute parts (0375015.HXP and 0375015.MXP) are ROHS3 compliant, meeting current environmental and regulatory standards.

Q: Are the physical dimensions identical across all three part numbers?

A: Yes. All three parts share identical dimensions of 0.275" Dia x 1.288" L (6.99mm x 32.72mm) and use the same 3AB, 3AG package format, ensuring direct mechanical compatibility in through-hole applications.

Q: Do the substitute parts carry the same regulatory approvals?

A: Yes. All three parts carry CE, CSA, and UL approvals, with identical breaking capacity (10 kA) at rated voltage and unlimited moisture sensitivity level (MSL 1).
