Substitute Part Grouping Explanation

Suitable substitutes for the S5M-M3/57T are determined strictly by matching core electrical and mechanical parameters. The following criteria were used to group substitute components:

Maximum DC Reverse Voltage (Vr) rating
Average Rectified Current (Io) rating
Maximum Forward Voltage (Vf) at specified current
Reverse Recovery Time (trr)
Current - Reverse Leakage at maximum Vr
Capacitance at specified test conditions
Mounting type and package/case (DO-214AB, SMC)
Compliance standards (RoHS, REACH)
Product status (Active) There is no deviation permitted from these parameters for a component to qualify as a substitute.
