Overview
The BC548BTA is a bipolar made by onsemi in a TO-92-3L package with 3 pins. -65℃~+150℃ 1 NPN 100mA 110 15nA 250mV 300MHz 30V 500mW 5V NPN TO-92-3L Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BC548, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-92_Inline, from KiCad's library), ready for a KiCad board. 4 are in stock at JLCPCB (part C900801). 3 open-source boards in 2 repositories on GitHub use it.

Questions
Is there a KiCad symbol and footprint for the BC548BTA?
Yes. The symbol is Transistor_BJT:BC548 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 BC548BTA?
TO-92-3L, with 3 pins. Its footprint is drawn on this page.
Where is the BC548BTA datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the BC548BTA?
JLCPCB lists it as part C900801, with 4 in stock; the sellers' links on this page open their listings.
What can replace the BC548BTA?
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 BC548BTA?
3 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
