Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0322015.VXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 15 A (exact match required)
• Voltage Rating: 65 V AC and 65 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: 200 A AC, 1 kA DC (exact match required)
• Melting I²t: 90 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 0.0043 Ohms (exact match required)
• Approval Agency: CE, UL (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part 0322015.HXP meets all these criteria and is therefore a direct parametric equivalent.
