Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0233003.MXF4P is determined by strict equivalence across the following critical parameters:

• Current Rating: 3 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Response Time: Medium Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 10kA (exact match required)
• Melting I²t: 26.24 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 0.0431 Ohms (exact match required)

Only parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the 0233003.MXF4P and 0233003.MXP are Active status products from Littelfuse Inc. with identical electrical and mechanical specifications. Both parts carry equivalent regulatory approvals (CE, CSA, KC, PSE, UL) and comply with ROHS3 and REACH requirements. Selection between these parts may be based on inventory availability, packaging format (Bulk), or regional sourcing logistics, as all technical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can 0233003.MXP be used as a direct replacement for 0233003.MXF4P?

A: Yes. Both parts are parametric equivalents with identical current rating (3A), voltage rating (125VAC), fuse type (Cartridge, Glass), package dimensions (5mm x 20mm), response time (Medium Blow), breaking capacity (10kA), melting I²t (26.24), operating temperature range (-55°C ~ 125°C), and DC cold resistance (0.0431 Ohms). Both require a fuse holder for mounting.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical regulatory approvals (CE, CSA, KC, PSE, UL) and meet the same environmental compliance standards (ROHS3 Compliant, REACH Unaffected).

Q: What determines if a fuse can substitute for the 0233003.MXF4P?

A: A substitute fuse must match all critical parameters: 3A current rating, 125V AC voltage rating, glass cartridge type, 5mm x 20mm package dimensions, medium-blow response, 10kA breaking capacity, 26.24 melting I²t, -55°C to 125°C operating range, and 0.0431 Ohms DC cold resistance.

Q: Does the packaging format affect electrical performance?

A: No. Both the main part and substitute are supplied in Bulk packaging. Packaging format does not affect the electrical or mechanical performance of the fuse itself.

Q: What is the inventory status for these parts?

A: The main part 0233003.MXF4P has 851 pieces in stock. The substitute part 0233003.MXP has 3081 pieces in stock. Both are new original components.
