Questions
Is there a KiCad symbol and footprint for the BC547B?
Yes. The symbol is Transistor_BJT:BC547 and the footprint Package_TO_SOT_THT:TO-92_Inline, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BC547B?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the BC547B datasheet?
LGE publishes it: the Datasheet link on this page opens it.
Where can I order the BC547B?
JLCPCB lists it as part C713613, with 13,259 in stock; the sellers' links on this page open their listings.
What can replace the BC547B?
Parts like it in the library: the 2N3904 by JSMSEMI, the 2N3904BU by onsemi, the PN2222ABU by onsemi and the MPSA92 by Foshan Blue Rocket Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BC547B?
45 boards in 36 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
