Substitute Part Grouping Explanation
Substitute parts are grouped strictly by matching the following electrical and mechanical parameters: diode configuration (2 Pair Common Anode), maximum DC reverse voltage (80V), average rectified current per diode (100mA), maximum forward voltage at specified current (1.2V @ 100mA), reverse recovery time (4ns), mounting type (Surface Mount), package (SC-74, SOT-457), and RoHS compliance status. These parameters ensure that the substitute part performs equivalently within defined application environments and mounting constraints.
