Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0318010.MXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)
• Melting I²t: 298 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 0.0093 Ohms (exact match required)
• Approval Agencies: CE, CSA, KC, PSE, UL (all certifications required)
• RoHS Status: ROHS3 Compliant (exact match required)

Only parts meeting all criteria are classified as parametric equivalents within the 318 series.

Parameter Comparison

Engineering Selection Recommendations

Both the 0318010.MXP and 0318010.HXP maintain Active product status with identical electrical, mechanical, and compliance specifications. Selection between these parts is based on availability and supply chain requirements. Both parts carry full international compliance certifications (CE, CSA, KC, PSE, UL) and ROHS3 compliance status, confirming suitability for regulated applications. The 0318010.HXP offers higher inventory availability (11,500 pcs vs. 1,211 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can 0318010.HXP be used as a direct replacement for 0318010.MXP?

A: Yes. Both parts are parametric equivalents with identical current ratings (10 A), voltage ratings (250 V AC), fuse type (cartridge, glass), response time (fast blow), package dimensions (3AB/3AG, 1/4" x 1-1/4"), mounting type (through hole), breaking capacity (200 A), melting I²t (298), operating temperature range (-55°C ~ 125°C), and DC cold resistance (0.0093 Ohms). All approval certifications and RoHS compliance are identical.

Q: What determines substitution eligibility for these fuses?

A: Substitution is determined by exact equivalence across current rating, voltage rating, fuse type, response time, package/case format, mounting type, breaking capacity, melting I²t, operating temperature range, DC cold resistance, and approval certifications. Deviation in any parameter disqualifies a part from substitution.

Q: Are there differences in mechanical fit between these parts?

A: No. Both parts share identical dimensions (0.275" Dia x 1.288" L / 6.99mm x 32.72mm) and package format (3AB, 3AG, 1/4" x 1-1/4" Axial), ensuring identical mechanical fit in through-hole applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts carry identical approval certifications (CE, CSA, KC, PSE, UL) and ROHS3 compliance status, confirming equivalence for regulated and safety-critical applications.

Q: What is the difference between these two part numbers?

A: The part numbers differ only in their suffix designation (.MXP vs. .HXP). All electrical, mechanical, and compliance parameters are identical. The difference reflects internal Littelfuse product line management and does not affect functional equivalence.
