Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 032502.5VXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 2.5 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 100A AC, 10kA DC (exact match required)
• Melting I²t: 136 (exact match required)

The substitute part 032502.5HXP meets all these criteria and is classified as a parametric equivalent. Both parts are manufactured by Littelfuse Inc. within the 325 series and maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 032502.5VXP and 032502.5HXP are active products manufactured by Littelfuse Inc. and maintain full compliance with international safety certifications including UL, CSA, CE, KC, and PSE standards. The 032502.5HXP differs only in approval agency designation (K-MARK listed instead of KC), which does not affect functional equivalence or electrical performance. Both parts carry ROHS3 compliance and REACH unaffected status, meeting environmental regulatory requirements. Selection between these parts may be based on inventory availability, procurement lead times, or regional certification preferences, as they are electrically and mechanically interchangeable for all circuit protection applications requiring 2.5 A slow-blow ceramic fuse protection at 250 V AC / 125 V DC.

Frequently Asked Questions (FAQ)

Q: Can the 032502.5HXP be used as a direct replacement for the 032502.5VXP?

A: Yes. Both parts are parametric equivalents with identical current ratings (2.5 A), voltage ratings (250 V AC, 125 V DC), response time (slow blow), package format (3AB/3AG, 1/4" x 1-1/4"), breaking capacity (100A AC, 10kA DC), and melting I²t (136). They are mechanically and electrically interchangeable.

Q: Are there any differences in certifications between these parts?

A: The 032502.5VXP lists KC certification while the 032502.5HXP lists K-MARK certification. Both parts maintain UL, CSA, CE, and PSE approvals. These certification variations do not affect functional equivalence or performance in circuit protection applications.

Q: What determines if a fuse can substitute for the 032502.5VXP?

A: A substitute fuse must match all critical parameters: 2.5 A current rating, 250 V AC and 125 V DC voltage ratings, slow-blow response time, 3AB/3AG package format with 1/4" x 1-1/4" dimensions, ceramic cartridge construction, through-hole mounting, 100A AC and 10kA DC breaking capacity, and 136 melting I²t value.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 032502.5VXP and 032502.5HXP are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Q: Can these fuses be used in applications requiring different voltage ratings?

A: No. These fuses are rated specifically for 250 V AC and 125 V DC operation. Use only in circuits matching these voltage specifications. Exceeding rated voltage will compromise circuit protection and safety.
