Questions
Is there a KiCad symbol and footprint for the BC858B?
Yes. The symbol is Transistor_BJT:BC858 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 BC858B?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BC858B datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BC858B?
JLCPCB lists it as part C596216, with 2,495 in stock; the sellers' links on this page open their listings.
What can replace the BC858B?
Parts like it in the library: the MMBT3904 by hongjiacheng, the S8050 by hongjiacheng, the SS8050 by hongjiacheng and the MMBT5551 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
