Substitute Part Grouping Explanation

Substitute parts for the 0324005.VXP are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria include:

• Current Rating: 5 A (exact match required)
• Voltage Ratings: 250 V AC and 125 V DC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Breaking Capacity: 750A AC, 10kA DC (exact match required)
• Melting I²t: 26 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 0.03 Ohms (exact match required)
• Mounting Type: Through Hole (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria and are manufactured by Littelfuse Inc. within the 324 series.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0324005.VXP, 0324005.HXP, and 0324005.MXP—are active products manufactured by Littelfuse Inc. and maintain full compliance with international regulatory standards including CE, CSA, PSE, and UL certifications. The parts are ROHS3 compliant and REACH unaffected, meeting environmental and hazardous substance requirements for global deployment.

Selection between these equivalent parts should be based on inventory availability and procurement lead times. The 0324005.MXP variant currently maintains the highest inventory level at 5038 pieces, followed by 0324005.HXP at 1010 pieces, and 0324005.VXP at 827 pieces. All parts are functionally interchangeable for applications requiring 5 A ceramic cartridge fuses with 250 V AC and 125 V DC ratings in 3AB/3AG package format.

Frequently Asked Questions (FAQ)

Q: Are these parts fully interchangeable in circuit design?

A: Yes. The 0324005.VXP, 0324005.HXP, and 0324005.MXP are parametric equivalents with identical electrical ratings, breaking capacity, response time, and physical dimensions. They are direct substitutes for one another in any application requiring a 5 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation.

Q: What determines substitution eligibility for these fuses?

A: Substitution is based on exact matching of current rating (5 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package format (3AB/3AG), breaking capacity (750A AC / 10kA DC), melting I²t value (26), operating temperature range (-55°C to 125°C), and mounting type (through hole). All identified substitutes meet these criteria.

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

A: The 0324005.VXP carries CE, CSA, KC, PSE, and UL certifications. The 0324005.HXP and 0324005.MXP carry CE, CSA, K-MARK, PSE, and UL certifications. Both certification sets meet international standards for industrial and consumer applications. Selection should align with regional regulatory requirements for your specific market.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. All three parts are rated for dual-voltage operation at 250 V AC and 125 V DC, with a DC cold resistance of 0.03 Ohms. They are suitable for AC, DC, and mixed-mode circuit applications within the specified voltage and current limits.

Q: What is the physical footprint compatibility?

A: All three parts share identical dimensions of 0.275" diameter by 1.288" length (6.99mm x 32.72mm) in 3AB/3AG axial package format. They are mechanically interchangeable in through-hole mounting applications without modification to PCB layouts or mechanical assemblies.
