Substitute Part Grouping Explanation

Substitution of the BC817-40/SNVL is determined by electrical and mechanical parameter equivalence. All substitute parts listed maintain identical specifications across the following critical parameters:

Transistor type: NPN
Collector current maximum: 500 mA
Collector-emitter breakdown voltage: 45 V
Vce saturation: 700 mV @ 50 mA, 500 mA
Collector cutoff current: 100 nA
DC current gain (hFE): 250 @ 100 mA, 1 V
Power dissipation: 250 mW
Transition frequency: 100 MHz
Operating temperature: 150°C
Package: TO-236-3 / SOT-23-3
Mounting: Surface Mount
RoHS and REACH compliance

Substitute parts are differentiated by product status (active vs. obsolete), packaging format (cut tape, digi-reel, tape & reel), automotive qualification level (AEC-Q100, AEC-Q101), and manufacturer source.
