Substitute Part Grouping Explanation

Substitution of the Littelfuse 0318.100VXP is permissible with parts that maintain identical electrical and mechanical specifications. The critical parameters that determine substitutability are:

• Current Rating: 100 mA (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: 35 A (exact match required)
• Approval Agencies: CE, CSA, UL (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The Littelfuse 0318.100HXP meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 0318.100VXP and 0318.100HXP are active products from Littelfuse Inc. with identical electrical performance, mechanical dimensions, and regulatory certifications. Selection between these parts may be based on inventory availability and supply chain considerations. Both parts carry full CE, CSA, and UL approvals and maintain ROHS3 compliance, ensuring compatibility with current regulatory requirements. The identical melting I²t value (0.00102) and DC cold resistance (11.28 Ohms) confirm functional equivalence in circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 0318.100HXP be used as a direct replacement for the 0318.100VXP?

A: Yes. Both parts are parametric equivalents with identical current ratings (100 mA), voltage ratings (250 V AC), fuse type (cartridge, glass), response time (fast blow), package dimensions (3AB, 3AG, 1/4" x 1-1/4"), and electrical characteristics. They are functionally interchangeable.

Q: Are there any differences in regulatory compliance between these parts?

A: No. Both parts carry identical approvals (CE, CSA, UL) and maintain ROHS3 compliance with REACH Unaffected status.

Q: What determines whether a fuse can substitute for the 0318.100VXP?

A: A substitute fuse must match all critical parameters: 100 mA current rating, 250 V AC voltage rating, fast-blow response time, 3AB/3AG cartridge glass package, 35 A breaking capacity, and identical thermal characteristics (melting I²t and DC cold resistance).

Q: Can I use a different current rating or voltage rating as a substitute?

A: No. Current and voltage ratings must be exact matches. Using a different rating will result in improper circuit protection and potential safety hazards.

Q: Are these parts suitable for both AC and DC applications?

A: Yes. Both parts are rated for 250 V AC/DC operation and are suitable for both application types within the specified voltage and current limits.
