Substitute Part Grouping Explanation

Substitution of ceramic cartridge fuses is determined by strict equivalence across electrical and mechanical parameters. The 0325025.VXP and its substitute 0325025.HXP are both Littelfuse Series 325 components that share identical specifications across all critical selection criteria:

• Current Rating: 25 A (exact match)
• Voltage Ratings: 250V AC / 125V DC (exact match)
• Response Characteristic: Slow Blow (exact match)
• Physical Package: 3AB, 3AG, 1/4" x 1-1/4" axial (exact match)
• Breaking Capacity: 400A AC, 600A DC (exact match)
• Melting I²t: 1030 (exact match)
• Operating Temperature: -55°C ~ 125°C (exact match)
• DC Cold Resistance: 0.0024 Ohms (exact match)
• RoHS Compliance: ROHS3 Compliant (exact match)

Both parts are active products with full regulatory approvals. The substitute maintains all functional and mechanical compatibility requirements for direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0325025.VXP and 0325025.HXP are active production components from Littelfuse Inc. with full regulatory compliance. The 0325025.HXP includes K-MARK certification in addition to the standard CE, CSA, PSE, and UL approvals present on the 0325025.VXP. Selection between these parts should be based on application-specific certification requirements and supply availability. Both components meet ROHS3 compliance and REACH unaffected status, making them suitable for modern electronics manufacturing environments. The identical electrical and mechanical specifications ensure functional interchangeability in all circuit applications where the 25A, 250V AC / 125V DC ceramic cartridge fuse specification is required.

Frequently Asked Questions (FAQ)

Q: Can the 0325025.HXP directly replace the 0325025.VXP in existing designs?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including current rating, voltage ratings, response time, package dimensions, breaking capacity, and operating temperature range. Direct substitution is supported without circuit redesign.

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

A: The primary difference is certification scope. The 0325025.HXP includes K-MARK certification, while the 0325025.VXP does not. All other specifications, including electrical performance, physical dimensions, and regulatory compliance (CE, CSA, PSE, UL), are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 3AB, 3AG package format with dimensions of 0.275" diameter x 1.288" length (6.99mm x 32.72mm). They are mechanically interchangeable in through-hole mounting applications.

Q: Do both parts have the same breaking capacity?

A: Yes. Both the 0325025.VXP and 0325025.HXP have identical breaking capacity ratings of 400A AC and 600A DC at rated voltage.

Q: Which part should I select for new designs?

A: Selection depends on your application's certification requirements. If K-MARK certification is required, use the 0325025.HXP. For applications requiring only CE, CSA, PSE, and UL certifications, either part is suitable. Verify current inventory availability with your supplier.
