• Voltage Rating - DC: 125 V (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" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 750 A AC, 10 kA DC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• DC Cold Resistance: 0.00505 Ohms (exact match required)
• Melting I²t: 292 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Product Status: Active (exact match required)

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

Parameter Comparison

Engineering Selection Recommendations

All three parts—0324015.VXP, 0324015.HXP, and 0324015.MXP—are active production components manufactured by Littelfuse and hold identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Compliance certification requirements for the end application
• Supply chain and procurement preferences

The 0324015.VXP includes KC and PSE certifications in addition to CE, CSA, and UL. The 0324015.HXP and 0324015.MXP include K-MARK certification in place of KC and PSE. All three parts maintain ROHS3 compliance and REACH unaffected status, suitable for applications requiring environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can 0324015.HXP or 0324015.MXP be used as direct replacements for 0324015.VXP?

A: Yes. All three parts are parametric equivalents with identical current rating (15 A), voltage ratings (250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package dimensions (3AB, 3AG, 1/4" x 1-1/4"), mounting type (through hole), breaking capacity (750 A AC, 10 kA DC), operating temperature range (-55°C to 125°C), and DC cold resistance (0.00505 Ohms).

Q: What is the difference between these substitute parts?

A: The primary differences are certification agency approvals and inventory availability. The 0324015.VXP includes KC and PSE certifications, while 0324015.HXP and 0324015.MXP include K-MARK certification. All three maintain CE, CSA, and UL approvals. Inventory levels differ: 0324015.VXP has 1124 units, 0324015.HXP has 9290 units, and 0324015.MXP has 20400 units in stock.

Q: Are these parts interchangeable in all applications?

A: Interchangeability depends on application-specific certification requirements. If the end application requires KC or PSE certification, use 0324015.VXP. If K-MARK certification is required, use 0324015.HXP or 0324015.MXP. For applications requiring only CE, CSA, and UL certifications, all three parts are suitable.

Q: What is the melting I²t value and why is it important?

A: The melting I²t value of 292 defines the thermal energy required to melt the fuse element. This parameter is identical across all three parts and ensures consistent overcurrent protection characteristics and response time.

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

A: Yes. All three parts are rated for 250 V AC and 125 V DC operation with a breaking capacity of 750 A AC and 10 kA DC at rated voltage. Application-specific circuit requirements must be verified to ensure voltage and current ratings are not exceeded.
