• Current Rating: 1.5 A
• Voltage Rating: 250 V AC / 125 V DC
• Response Time: Fast Blow
• Package / Case: 2AG, 5mm x 15mm
• Breaking Capacity: 35 A AC, 10 kA DC
• Melting I²t: 0.8
• DC Cold Resistance: 0.0712 Ohms
• Operating Temperature Range: -55°C to 125°C
• Regulatory Approvals: CE, CSA, PSE, UL
• Environmental Compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts 022501.5HXP and 022501.5MXP are parametric equivalents that differ only in internal construction or manufacturing process designation (indicated by the suffix letter), while maintaining full electrical and mechanical compatibility with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—022501.5VXP, 022501.5HXP, and 022501.5MXP—are active products from Littelfuse Inc. with identical electrical specifications and full regulatory compliance. Selection between these equivalents may be based on procurement availability, inventory status, or supply chain requirements, as they are functionally interchangeable for all circuit protection applications within the specified voltage and current parameters.

All substitute parts carry the same certifications (CE, CSA, PSE, UL) and environmental compliance status (ROHS3 Compliant, REACH Unaffected), ensuring compatibility with regulatory requirements across global markets.

Frequently Asked Questions (FAQ)

Q: Can 022501.5HXP and 022501.5MXP be used interchangeably with 022501.5VXP?

A: Yes. All three part numbers are parametric equivalents with identical electrical and mechanical specifications. They are fully interchangeable in any application requiring a 1.5 A, 250 V AC / 125 V DC fast-blow glass cartridge fuse in the 2AG form factor.

Q: What does the suffix letter (V, H, M) indicate?
