• Voltage Rating - DC: 125 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 2AG, 5mm x 15mm (exact match required)
• Breaking Capacity @ Rated Voltage: 100A AC, 10kA DC (exact match required)
• Melting I²t: 4.62 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 0.0317 Ohms (exact match required)
• Approval Agencies: CE, CSA, PSE, UL (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitute parts maintain identical specifications across these parameters, ensuring direct interchangeability in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—0225003.VXP, 0225003.HXP, and 0225003.MXP—are functionally equivalent for circuit protection applications requiring 3A fast-blow fuse cartridges rated for 250VAC and 125VDC operation. Selection among these alternatives may be based on inventory availability and supply chain considerations. All parts maintain Active product status and carry identical regulatory certifications (CE, CSA, PSE, UL) with ROHS3 compliance, ensuring suitability for applications subject to environmental and safety standards. The 2AG package format and mechanical dimensions are consistent across all options, guaranteeing compatibility with standard fuse holders designed for this cartridge type.

Frequently Asked Questions (FAQ)

Q: Can 0225003.HXP or 0225003.MXP be used as direct replacements for 0225003.VXP?

A: Yes. All three part numbers are parametric equivalents with identical electrical ratings (3A, 250VAC, 125VDC), response characteristics (fast-blow), mechanical dimensions (2AG, 5mm x 15mm), breaking capacity, thermal characteristics, and regulatory approvals. Direct substitution is supported without circuit modification.

Q: Are there differences in fuse holder compatibility?

A: No. All three parts require the same holder type and are mechanically identical in the 2AG 5mm x 15mm package format. Any fuse holder designed for 2AG cartridges will accommodate all three part numbers.

Q: Do all substitute parts carry the same safety certifications?

A: Yes. All parts carry CE, CSA, PSE, and UL certifications and maintain ROHS3 compliance. Regulatory requirements are identical across all three options.

Q: What is the significance of the different part number suffixes (VXP, HXP, MXP)?

A: The suffixes indicate different manufacturing batches or packaging configurations within the Littelfuse 225 series. The electrical and mechanical specifications remain identical, and the parts are fully interchangeable.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. All parts are rated for dual-voltage operation: 250VAC and 125VDC. The breaking capacity specifications (100A AC, 10kA DC) apply to their respective voltage domains.
