Substitute Part Grouping Explanation

Substitutes are determined strictly by matching the following allowed electrical and mechanical parameters: transistor type, maximum collector current, maximum collector-emitter voltage, maximum power dissipation, mounting type, and package. These parameters ensure compatibility in function and physical mounting. Only substitute parts with equivalent values for these parameters are considered valid.
