Substitute Part Grouping Explanation

Substitution of the SCHURTER 2030.0244 is determined by strict equivalence across the following critical parameters:

• Current Rating: 315mA (exact match required)
• Voltage Rating: 125 VAC and 125 VDC (exact match required)
• Mounting Type: Through Hole (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: Radial, Can configuration (exact match required)
• Physical Dimensions: 0.252" Dia x 0.346" (6.40mm x 8.80mm) (exact match required)
• Breaking Capacity: 100A @ Rated Voltage (exact match required)
• Melting I²t: 0.025 (exact match required)

The SCHURTER 0034.4244 meets all substitution criteria as an active product within the MSF 125 series, providing direct functional equivalence to the obsolete 2030.0244.
