Substitute Part Grouping Explanation

Substitute parts for the RS1MFS MWG are identified based on strict parametric equivalence within the RS1M base product family. All substitute candidates maintain identical electrical specifications: 1000 V reverse voltage rating, 1 A average rectified current, 1.3 V forward voltage drop at 1 A, 500 ns reverse recovery time, and 5 µA reverse leakage current at rated voltage. All substitutes share the SOD-128 surface mount package, identical temperature range (-55°C to 150°C), and ROHS3 compliance status.

Substitution logic is determined by the following key parameters:

Voltage - DC Reverse (Vr) (Max): 1000 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
Reverse Recovery Time (trr): 500 ns
Package / Case: SOD-128
Mounting Type: Surface Mount
Operating Temperature Range: -55°C ~ 150°C
