Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3410.0021.04 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Current Rating: 200 mA
• Voltage Rating: 125 V AC / 125 V DC
• Response Time: Fast Blow
• Mounting Type: Surface Mount
• Package / Case: 2-SMD, Square End Block
• Breaking Capacity: 50 A AC / 300 A DC
• Melting I²t: 0.0008
• DC Cold Resistance: 1.02 Ohms
• Operating Temperature Range: -55°C to 150°C
• Approval Agency: cURus
• RoHS Status: ROHS3 Compliant

All substitute parts listed maintain these exact specifications, ensuring direct functional and mechanical interchangeability without circuit redesign or board layout modification.

Parameter Comparison
