Overview
The BC547A is a bipolar made by DIOTEC in a TO-92 package with 3 pins. 100mA 110 15nA 300MHz 45V 600mV NPN TO-92 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BC547, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-92_Inline, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3201603). 4 open-source boards in 4 repositories on GitHub use it.

Questions
Is there a KiCad symbol and footprint for the BC547A?
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 BC547A?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the BC547A datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the BC547A?
JLCPCB lists it as part C3201603, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BC547A?
Parts like it in the library: the S8050 by JSMSEMI, the S8550 by JSMSEMI, the 2N3904 by JSMSEMI and the 2N3904BU by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BC547A?
4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
