Littelfuse 0322025.VXP Ceramic Fuse 25A 65VAC/VDC Equivalent & Substitute Parts

Part Overview

The Littelfuse 0322025.VXP is an active ceramic cartridge fuse rated for 25 amperes at 65 volts AC/DC. This fast-blow fuse is designed for applications requiring reliable overcurrent protection in the 322 series family. The part is housed in a 3AB/3AG form factor (0.250" diameter × 1.250" length) and requires a compatible fuse holder for installation. Substitute parts are identified when identical electrical and mechanical specifications are maintained across the product line, ensuring direct interchangeability without circuit redesign.

• Current Rating: 25 A
• Voltage Rating (AC/DC): 65 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Fast Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Breaking Capacity: 200 A AC, 1 kA DC
• Melting I²t: 325
• Operating Temperature Range: -55°C to 125°C
• DC Cold Resistance: 0.0029 Ohms
• Approval Agencies: CE, UL
• RoHS Compliance: ROHS3 Compliant

All substitute parts listed maintain these specifications without deviation, ensuring functional and mechanical interchangeability within the 322 series.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0322025.VXP, 0322025.HXP, and 0322025.MXP—are active products from Littelfuse Inc. with identical electrical and mechanical specifications. Selection among these substitutes may be based on inventory availability and lead time considerations. All parts carry CE and UL approvals and maintain ROHS3 compliance, meeting regulatory requirements for industrial and commercial applications. The interchangeability of these parts is guaranteed by their parametric equivalence across all critical performance and safety parameters.

Frequently Asked Questions (FAQ)

Q: Can 0322025.HXP and 0322025.MXP be used interchangeably with 0322025.VXP?

A: Yes. All three parts are parametrically equivalent ceramic cartridge fuses with identical current ratings (25 A), voltage ratings (65 V AC/DC), response characteristics (fast blow), and physical dimensions (3AB/3AG, 0.250" × 1.250"). They are direct substitutes within the same circuit application.

Q: What determines whether a fuse can substitute for the 0322025.VXP?

A: Substitution requires matching of current rating, voltage rating (both AC and DC), fuse type (ceramic cartridge), response time (fast blow), package dimensions, breaking capacity, and thermal characteristics. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Are there any compliance or certification differences between these substitute parts?

A: No. All three parts carry identical CE and UL approvals, maintain ROHS3 compliance, and are classified as REACH Unaffected. Regulatory compliance is uniform across the substitute group.

Q: What is the physical compatibility requirement for these fuses?

A: These fuses require a compatible 3AB or 3AG fuse holder. The 0.250" diameter × 1.250" length specification ensures mechanical fit within standard cartridge fuse holders designed for this form factor.

Q: Does the DC cold resistance value affect substitution eligibility?

A: Yes. The DC cold resistance of 0.0029 Ohms is a critical parameter for circuit performance. All substitute parts maintain this identical value, ensuring equivalent electrical behavior in DC applications.
