Littelfuse 0224005.MXUP Glass Cartridge Fuse 5A 250VAC 2AG Equivalent & Substitute Parts

Part Overview

The Littelfuse 0224005.MXUP is a 5A 250VAC fast-blow glass cartridge fuse in 2AG package format (5mm x 15mm axial). This component is classified as Active product status and is designed for through-hole mounting applications requiring overcurrent protection in AC/DC circuits. Equivalent and substitute parts are identified when circuit requirements allow for alternative voltage ratings or packaging variants while maintaining identical current ratings, response characteristics, and physical dimensions.

Substitute Part Grouping Explanation

Substitution of the Littelfuse 0224005.MXUP is determined by the following critical parameters:

Current Rating (5A): All substitute parts must maintain identical 5A current rating to ensure proper overcurrent protection function.

Fuse Type & Package (2AG Glass Cartridge, 5mm x 15mm): Physical and electrical compatibility requires identical package format and glass cartridge construction.

Response Time (Fast Blow): Substitutes must maintain fast-blow characteristics to preserve circuit protection timing.

Voltage Rating: The main part operates at 250VAC. Substitutes may operate at lower voltage ratings (125VAC) only when the application circuit voltage does not exceed the substitute's rated voltage.

Mounting Type (Through Hole): All substitutes must support through-hole mounting configuration.

Electrical Characteristics (Breaking Capacity, Melting I²t, DC Cold Resistance): These parameters remain consistent across all listed substitutes.

Compliance & Certifications: All substitutes maintain CE, CSA, and UL approvals, with the parametric equivalent offering additional METI certification.

Engineering Selection Recommendations

0224005.MXUP (Primary Selection): Use this part number for applications requiring 250VAC rated protection. All regulatory certifications (CE, CSA, UL) are current and the part maintains Active product status with 2000 units in stock.

0224005.HXUP (Voltage-Reduced Substitute): This part is suitable only for circuits operating at 125VAC or lower. The reduced voltage rating makes this substitute applicable to lower-voltage applications while maintaining identical current protection and response characteristics. All certifications remain valid. Inventory availability is 1181 units.

0224005.MXUSLP (Parametric Equivalent): This part provides identical electrical and mechanical specifications to the main part (0224005.MXUP) with the addition of METI certification. Use this part when METI compliance is required for specific regional or application requirements. Inventory availability is 1990 units.

All three parts maintain Active product status and full regulatory compliance. Selection depends on circuit voltage requirements and regional certification needs.

Frequently Asked Questions (FAQ)

Q: Can 0224005.HXUP be used in place of 0224005.MXUP?

A: Only if the application circuit operates at 125VAC or lower. The 0224005.HXUP has a reduced voltage rating of 125VAC compared to the 250VAC rating of 0224005.MXUP. Using a lower-rated fuse in a higher-voltage circuit creates a safety hazard.

Q: What is the difference between 0224005.MXUP and 0224005.MXUSLP?

A: Both parts have identical electrical and mechanical specifications (5A, 250VAC, 2AG package, fast-blow response). The primary difference is that 0224005.MXUSLP includes METI certification in addition to CE, CSA, and UL certifications. Select 0224005.MXUSLP when METI compliance is required.

Q: Are all substitute parts in the same 2AG package?

A: Yes. All listed parts use the 2AG package format (5mm x 15mm axial) and are compatible with through-hole mounting applications designed for this package.

Q: Do all parts have the same current rating?

A: Yes. All parts are rated for 5A current protection with identical fast-blow response time and 100A breaking capacity.

Q: What certifications apply to all substitute parts?

A: All parts carry CE, CSA, and UL certifications. The 0224005.MXUSLP additionally includes METI certification.

Q: Are these parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant.
