Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0235006.MXEP is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 6 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) form factor (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 10 kA minimum at rated voltage
• Operating Temperature Range: -55°C ~ 125°C (minimum coverage required)
• RoHS Compliance: ROHS3 Compliant (required)

The Bel Fuse Inc. 5MFP 6-R meets all mandatory substitution criteria and is classified as a direct equivalent for the Littelfuse 0235006.MXEP.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 0235006.MXEP and Bel Fuse Inc. 5MFP 6-R are active products with ROHS3 compliance and equivalent electrical and mechanical specifications. The Littelfuse part carries broader approval agency coverage (CE, CSA, KC, PSE, UL) compared to the Bel Fuse part (CE, CSA, PSE). Selection between these components should be based on application-specific certification requirements and supply chain availability. The Littelfuse 0235006.MXEP is recommended where full approval agency coverage is mandatory. The Bel Fuse Inc. 5MFP 6-R serves as a direct functional equivalent where CE, CSA, and PSE certifications satisfy application requirements.

Frequently Asked Questions (FAQ)

Q: Can the Bel Fuse Inc. 5MFP 6-R replace the Littelfuse 0235006.MXEP in all applications?

A: The 5MFP 6-R meets all core electrical and mechanical substitution criteria. However, application approval requirements must be verified. The Littelfuse part includes KC and UL certifications not present on the Bel Fuse part. Confirm that CE, CSA, and PSE certifications satisfy your equipment's regulatory requirements before substitution.

Q: Are the physical dimensions interchangeable?

A: Both parts use the 5mm x 20mm (Axial) package form factor for through-hole mounting. Minor dimensional variations exist (Littelfuse: 5.80mm Dia x 22.50mm L; Bel Fuse: 5.50mm Dia x 21.00mm L), but both fit standard 5x20mm fuse holders without modification.

Q: What is the significance of the different Melting I²t values?

A: The Melting I²t parameter (47.325 for Littelfuse; 65 for Bel Fuse) indicates thermal energy absorption before fuse element melting. Both parts are rated for 6 A fast-blow response and meet the 10 kA breaking capacity requirement. The difference reflects manufacturing tolerance and thermal design variation between manufacturers but does not affect substitution eligibility for equivalent circuit protection.

Q: Are both parts RoHS compliant?

A: Yes, both the Littelfuse 0235006.MXEP and Bel Fuse Inc. 5MFP 6-R are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component manufacturing and use.
