Substitute Part Grouping Explanation

The substitute part 0224007.HXUP is classified as a direct equivalent based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

Critical Parameters for Substitution:

• Current Rating: 7 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Package / Case: 2AG, 5mm x 15mm (Axial) (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 500 A (exact match required)
• Melting I²t: 40 (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Approval Agencies: CE, CSA, PSE, UL (exact match required)

The substitute part meets all critical parameters without deviation, confirming full interchangeability in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0224007.MXUP and 0224007.HXUP maintain active product status with identical compliance certifications (CE, CSA, PSE, UL) and ROHS3 compliance. Selection between these parts is based on supply chain availability and inventory management rather than technical performance differentiation. Both parts are suitable for direct substitution in 7A 125VAC circuit protection applications requiring fast-blow response characteristics and 500A breaking capacity.

Frequently Asked Questions (FAQ)

Q: Can 0224007.HXUP be used as a direct replacement for 0224007.MXUP?

A: Yes. Both parts are identical in electrical specifications (7A, 125VAC, fast-blow), mechanical dimensions (2AG, 5mm x 15mm), breaking capacity (500A), and regulatory approvals (CE, CSA, PSE, UL). Direct substitution is supported without circuit modification.
