Questions
Is there a KiCad symbol and footprint for the BC857B?
Yes. The symbol is Transistor_BJT:BC857 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BC857B?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BC857B datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the BC857B?
JLCPCB lists it as part C46962155, with 297 in stock; the sellers' links on this page open their listings.
What can replace the BC857B?
Parts like it in the library: the S8050 by hongjiacheng, the SS8050 by hongjiacheng, the MMBT5551 by hongjiacheng and the MMBT5401 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
