Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 0318006.MXP are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Current Rating: 6 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: 118 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 0.0178 Ohms (exact match required)
• Regulatory Compliance: CE, CSA, KC, PSE, UL (all certifications required)

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

The 0318006.MXP currently has 833 pieces in stock, while the 0318006.HXP has 1235 pieces available. Either part is suitable for direct substitution in applications requiring a 6 A, 250 V AC/DC fast-blow glass cartridge fuse with 3AB/3AG package configuration and through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can the 0318006.HXP be used as a direct replacement for the 0318006.MXP?

A: Yes. The 0318006.HXP is a parametric equivalent with identical electrical ratings (6 A, 250 V AC/DC), fuse type (cartridge, glass), response time (fast blow), package configuration (3AB, 3AG, 1/4" x 1-1/4"), mounting type (through hole), breaking capacity (200 A), melting I²t (118), operating temperature range (-55°C ~ 125°C), and DC cold resistance (0.0178 Ohms). Both parts carry identical regulatory certifications (CE, CSA, KC, PSE, UL) and RoHS3 compliance status.

Q: Are there any mechanical compatibility differences between these parts?

A: No. Both parts share identical physical dimensions (0.275" Dia x 1.288" L / 6.99mm x 32.72mm) and package specifications (3AB, 3AG, 1/4" x 1-1/4" Axial). They are mechanically interchangeable in through-hole mounting applications.

Q: What determines substitution eligibility for this fuse category?

A: Substitution eligibility is determined by exact equivalence across current rating, voltage rating, fuse type, response time, package configuration, mounting type, breaking capacity, melting I²t, operating temperature range, DC cold resistance, and regulatory certifications. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 0318006.MXP and 0318006.HXP carry identical approvals from CE, CSA, KC, PSE, and UL agencies and are ROHS3 compliant. They are suitable for applications requiring these certifications.

Q: What is the difference between the .MXP and .HXP designations?

A: The .MXP and .HXP designations represent different packaging or distribution variants from Littelfuse Inc. Both parts are electrically and mechanically identical with the same performance specifications and certifications.
