Substitute Part Grouping Explanation

The Littelfuse 0225006.HXUP qualifies as a direct substitute for the 0225006.MXUP based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Current Rating: 6 A (identical)
• Voltage Rating (AC): 125 V (identical)
• Fuse Type: Cartridge, Glass (identical)
• Package / Case: 2AG, 5mm x 15mm (identical)
• Response Time: Fast Blow (identical)
• Breaking Capacity @ Rated Voltage: 500A (identical)
• DC Cold Resistance: 0.0154 Ohms (identical)
• Melting I²t: 22.1 (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Approval Agencies: CE, CSA, PSE, UL (identical)
• RoHS Status: ROHS3 Compliant (identical)

Both parts are manufactured by Littelfuse Inc. and belong to the 225 series. The substitute maintains full compatibility with existing 2AG fuse holders and circuit designs without modification.

Parameter Comparison

Engineering Selection Recommendations

Both the 0225006.MXUP and 0225006.HXUP are Active products with identical compliance certifications across CE, CSA, PSE, and UL standards. Selection between these parts should be based on inventory availability and supply chain requirements. Both components satisfy ROHS3 compliance and REACH unaffected status, making either suitable for applications requiring regulatory compliance in consumer and industrial markets. The identical electrical characteristics, breaking capacity, and thermal performance ensure direct interchangeability in 2AG fuse holder applications without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the 0225006.HXUP replace the 0225006.MXUP in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (6A), voltage ratings (125VAC), package dimensions (2AG, 5mm x 15mm), and response characteristics (Fast Blow). Direct substitution is possible without circuit modification.

Q: Are there any differences in approval certifications between these parts?

A: No. Both parts carry identical approval certifications: CE, CSA, PSE, and UL. Both are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the 2AG package designation?

A: The 2AG designation specifies the physical form factor (5mm diameter x 15mm length) and establishes compatibility with standard 2AG fuse holders. Both substitute parts conform to this specification.

Q: Do these fuses require a specific holder type?

A: Yes. Both the 0225006.MXUP and 0225006.HXUP require a 2AG fuse holder for installation. They are not designed for direct PCB mounting.

Q: What is the melting I²t value and why is it important?

A: The melting I²t value of 22.1 defines the thermal energy required to melt the fuse element. This parameter is identical for both parts and ensures consistent protection characteristics in the circuit.

Q: Are there temperature limitations for these fuses?

A: Both parts operate within the range of -55°C to 125°C. Applications outside this range require alternative fuse selection.
