Questions

Is there a KiCad symbol and footprint for the BC547?

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 BC547?

TO-92, with 3 pins. Its footprint is drawn on this page.

Where is the BC547 datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the BC547?

JLCPCB lists it as part C47089404, with 6,784 in stock; the sellers' links on this page open their listings.

What can replace the BC547?

Parts like it in the library: the 2N3904 by JSMSEMI, the 2N3904BU by onsemi, the PN2222ABU by onsemi and the BC547B by LGE. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BC547?

943 boards in 707 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
