Littelfuse 0225008.MXUP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0225008.MXUP is an 8A 125VAC fast-blow glass cartridge fuse in 2AG package format (5mm x 15mm). This component is designed for circuit protection in AC and DC applications requiring rapid response to overcurrent conditions. The part maintains active product status with full compliance to international safety standards including CE, CSA, PSE, and UL certifications. Substitute parts are identified when identical electrical specifications, mechanical dimensions, and approval certifications are maintained across alternative manufacturer part numbers or packaging variants.

Substitute Part Grouping Explanation

The Littelfuse 0225008.HXUP qualifies as a direct substitute for the 0225008.MXUP based on strict equivalence across all critical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Current rating: 8 A (identical)
• Voltage rating: 125 V AC (identical)
• Fuse type and response: Cartridge, Glass, Fast Blow (identical)
• Physical package: 2AG, 5mm x 15mm (identical)
• Breaking capacity: 500A at rated voltage (identical)
• Thermal characteristics: Melting I²t of 56 (identical)
• Operating temperature range: -55°C to 125°C (identical)
• DC cold resistance: 0.0107 Ohms (identical)
• Regulatory compliance: CE, CSA, PSE, UL certifications (identical)
• Environmental compliance: ROHS3 Compliant, REACH Unaffected (identical)

Both parts are manufactured by Littelfuse Inc. within the 225 series and maintain active product status. The substitution represents a packaging or inventory variant rather than a functional difference.

Parameter Comparison

Engineering Selection Recommendations

Both the 0225008.MXUP and 0225008.HXUP are active products from Littelfuse Inc. with identical electrical specifications and mechanical dimensions. Selection between these part numbers may be determined by inventory availability or packaging preferences, as both maintain full compliance with CE, CSA, PSE, and UL certifications. The ROHS3 compliance and REACH unaffected status confirm suitability for regulated markets. Either part number is functionally equivalent for 8A 125VAC circuit protection applications requiring fast-blow response characteristics in 2AG cartridge format.

Frequently Asked Questions (FAQ)

Q: Can 0225008.HXUP be used as a direct replacement for 0225008.MXUP?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (8A), voltage ratings (125VAC), package dimensions (2AG, 5mm x 15mm), response characteristics (fast blow), and regulatory certifications (CE, CSA, PSE, UL).

Q: What determines if a fuse is a valid substitute?

A: Valid substitution requires matching current rating, voltage rating, fuse type (cartridge glass), package format (2AG), response time (fast blow), breaking capacity (500A), thermal characteristics (I²t value of 56), operating temperature range (-55°C to 125°C), and regulatory approvals.

Q: Are there any differences in the physical dimensions between these parts?

A: No. Both parts share identical dimensions of 0.177" diameter x 0.570" length (4.50mm x 14.48mm) and are compatible with the same 2AG fuse holders.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both 0225008.MXUP and 0225008.HXUP are ROHS3 compliant, REACH unaffected, and carry identical approval certifications from CE, CSA, PSE, and UL.

Q: What is the DC cold resistance specification and why is it important?

A: Both parts have a DC cold resistance of 0.0107 Ohms. This specification is critical for applications where DC circuits are protected, as it affects voltage drop and thermal performance under load conditions.
