Substitute Part Grouping Explanation

Substitution eligibility for the 0326.200VXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Breaking Capacity: 100 A @ Rated Voltage (exact match required)
• Melting I²t: 0.213 (exact match required)
• DC Cold Resistance: 6.77 Ohms (exact match required)

The substitute part 0326.200MXP meets all these criteria and is therefore classified as a parametric equivalent.
