Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0224008.MXUP are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria include:

• Current Rating: 8 A (exact match required)
• Voltage Rating: 125 V AC (exact match required)
• Package Format: 2AG, 5mm x 15mm axial (exact match required)
• Fuse Type: Glass cartridge with fast-blow response (exact match required)
• Mounting Configuration: Through-hole (exact match required)
• Breaking Capacity: 500 A @ rated voltage (exact match required)
• Thermal Characteristics: Melting I²t of 56 (exact match required)
• Compliance: CE, CSA, PSE, UL certifications (exact match required)

Only parts meeting all these parameters are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the 0224008.MXUP and 0224008.HXUP are active products from Littelfuse Inc. with identical electrical specifications, mechanical dimensions, and regulatory certifications. Selection between these parts may be based on inventory availability and packaging format (both supplied in bulk). The 0224008.HXUP maintains higher inventory levels (4795 pcs) compared to the 0224008.MXUP (952 pcs), which may influence procurement decisions for high-volume applications. Both parts satisfy CE, CSA, PSE, and UL compliance requirements and are ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the 0224008.HXUP be used as a direct replacement for the 0224008.MXUP?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (8 A), voltage ratings (125 V AC), package formats (2AG, 5mm x 15mm), response characteristics (fast-blow), and regulatory certifications.

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

A: Valid substitutes must match all critical parameters: current rating, voltage rating, fuse type (glass cartridge), package format (2AG axial), response time (fast-blow), mounting configuration (through-hole), breaking capacity (500 A), melting I²t (56), and regulatory approvals (CE, CSA, PSE, UL).

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

A: No. Both parts share identical dimensions of 0.185" diameter x 0.570" length (4.70mm x 14.48mm) and are packaged in the standard 2AG format.

Q: Do both parts have the same thermal operating range?

A: Yes. Both the 0224008.MXUP and 0224008.HXUP operate across the same temperature range of -55°C to 125°C.

Q: Are there compliance or certification differences between these substitutes?

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