Littelfuse 0225010.MXUP Glass Cartridge Fuse 10A 125VAC 2AG Equivalent & Substitute Parts

Part Overview

The Littelfuse 0225010.MXUP is a fast-blow glass cartridge fuse rated for 10 A at 125 V AC/DC, housed in a 2AG form factor (5mm x 15mm). This component is designed for circuit protection in applications requiring rapid response to overcurrent conditions. The part maintains Active product status with full compliance to CE, CSA, PSE, and UL approval agencies. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, response characteristics, and regulatory certifications to ensure direct interchangeability in protected circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0225010.MXUP are identified through strict parameter matching across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that determine interchangeability:

Electrical Parameters: Current rating (10 A), voltage rating (125 V AC), response time (Fast Blow), breaking capacity (500 A), and melting I²t value (116) must be identical.

Mechanical Parameters: Package form factor (2AG), physical dimensions (5mm x 15mm), and mounting requirement (Requires Holder) must match exactly.

Regulatory & Compliance Parameters: All substitute parts must maintain the same approval agency certifications (CE, CSA, PSE, UL), RoHS compliance status (ROHS3), and operating temperature range (-55°C to 125°C).

Resistance Characteristics: DC cold resistance (0.0075 Ohms) must be identical to ensure equivalent circuit behavior.

Parts meeting all these criteria are classified as direct manufacturer equivalents and parametric equivalents, suitable for one-to-one replacement in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0225010.MXUP, 0225010.HXUP, and 0225010.VXUP—are functionally equivalent for circuit protection applications requiring 10 A fast-blow fuse protection at 125 V AC/DC. Each part maintains Active product status and carries identical regulatory certifications (CE, CSA, PSE, UL), ensuring compliance with international safety standards.

Selection between these parts may be based on inventory availability and supply chain considerations. The 0225010.HXUP variant currently has the highest inventory level (2021 units), followed by 0225010.MXUP (1779 units) and 0225010.VXUP (976 units). All parts are ROHS3 compliant and suitable for applications with operating temperature requirements spanning -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can 0225010.HXUP and 0225010.VXUP be used as direct replacements for 0225010.MXUP?

A: Yes. Both parts are direct equivalents with identical electrical ratings (10 A, 125 V AC), response characteristics (Fast Blow), mechanical dimensions (2AG, 5mm x 15mm), and regulatory certifications. They are suitable for one-to-one replacement in any circuit application using the 0225010.MXUP.

Q: What determines whether a fuse can substitute for the 0225010.MXUP?

A: Substitution requires matching of current rating (10 A), voltage rating (125 V AC), fuse type (Cartridge, Glass), package form factor (2AG, 5mm x 15mm), response time (Fast Blow), breaking capacity (500 A), melting I²t (116), DC cold resistance (0.0075 Ohms), and approval agency certifications (CE, CSA, PSE, UL).

Q: Are there any differences in performance between these three part numbers?

A: No. All three parts share identical electrical specifications, mechanical dimensions, response characteristics, and regulatory compliance. Differences exist only in manufacturing lot codes (indicated by the suffix variations: MXUP, HXUP, VXUP) and current inventory levels.

Q: What is the 2AG package specification?

A: The 2AG designation refers to a standardized glass cartridge fuse form factor with dimensions of 5mm diameter by 15mm length (0.177" Dia x 0.570" L). This package requires installation in a compatible fuse holder designed for 2AG cartridges.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts—0225010.MXUP, 0225010.HXUP, and 0225010.VXUP—are ROHS3 compliant and suitable for applications subject to RoHS regulations.
