Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.4210 are qualified based on exact matching of the following critical parameters:

• Current Rating: 125 mA
• Voltage Rating (AC/DC): 125 V
• Response Time: Fast Blow
• Mounting Type: Through Hole
• Package / Case: Radial, Can
• Breaking Capacity @ Rated Voltage: 100 A
• Melting I²t: 0.0015
• Operating Temperature Range: -25°C ~ 85°C
• Physical Dimensions: 0.252" Dia x 0.346" H (6.40mm x 8.80mm)

Only parts meeting all these parameters are listed as direct equivalents. Deviations in any parameter require circuit re-evaluation and are not considered substitutes.

Parameter Comparison

Engineering Selection Recommendations
