Substitute Part Grouping Explanation

The substitute part 0225005.HXUP is classified as a direct equivalent based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Current Rating: 5 A (exact match)
• Voltage Rating (AC): 125 V (exact match)
• Fuse Type: Cartridge, Glass (exact match)
• Package / Case: 2AG, 5mm x 15mm (exact match)
• Response Time: Fast Blow (exact match)
• Breaking Capacity @ Rated Voltage: 100A (exact match)
• Melting I²t: 17 (exact match)
• Operating Temperature Range: -55°C to 125°C (exact match)
• DC Cold Resistance: 0.0186 Ohms (exact match)
• Compliance: ROHS3 Compliant, CE/CSA/UL Approved (exact match)

The substitute part differs only in manufacturer packaging designation and inventory source, with no functional or electrical differences.

Frequently Asked Questions (FAQ)

Q: Can 0225005.HXUP be used as a direct replacement for 0225005.MXUP?

A: Yes. Both parts are identical in all electrical and mechanical specifications, including current rating, voltage rating, package dimensions, response time, and breaking capacity. They are functionally interchangeable.

Q: What does the 2AG package designation mean?

A: 2AG refers to a standardized glass cartridge fuse format with dimensions of 5mm diameter by 15mm length. This package size is compatible with standard 2AG fuse holders.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both parts operate across the same temperature range of -55°C to 125°C and have identical DC cold resistance values.

Q: What is the significance of the "Fast Blow" response time?

A: Fast Blow indicates the fuse will open quickly when current exceeds the 5A rating, providing rapid circuit protection. This characteristic is identical in both substitute parts.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both 0225005.MXUP and 0225005.HXUP carry CE, CSA, and UL approvals and are ROHS3 compliant.
