Substitute Part Grouping Explanation

Substitute relationships in bipolar (BJT) transistor selection are determined strictly by match or compatibility in transistor type, maximum collector-emitter voltage, maximum collector current, saturation voltage at specified base and collector current, collector cutoff current, minimum DC current gain at specified collector current and voltage, maximum power dissipation, transition frequency, operating temperature range, mounting type, and package type. Only parts matching these key parameters or falling within specified constraints are considered suitable substitutes.
