Substitute Part Grouping Explanation

Substitute and similar parts are grouped strictly by matching the essential electrical and package parameters that define proper replacement for a pre-biased NPN BJT. Matching criteria include transistor type, maximum collector current, maximum collector-emitter breakdown voltage, base and emitter resistor values, DC current gain, Vce saturation, cutoff current, transition frequency, maximum power rating, mounting method, and package compatibility. Only parts explicitly listed with equivalent or permissible values across these fields are considered valid substitutes.
