Questions
Is there a KiCad symbol and footprint for the BC557B?
Yes. The symbol is LibrePCB_Base:BC557 and the footprint Package_TO_SOT_THT:TO-92L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BC557B?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the BC557B datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the BC557B?
JLCPCB lists it as part C3201606, with 110 in stock; the sellers' links on this page open their listings.
What can replace the BC557B?
Parts like it in the library: the S9013 by HXY MOSFET, the 2N2222A by Slkor, the 2N2222A-338 by ALJ and the 2N5401H-98 by ALJ. Check their datasheets: a part that fits the footprint may still differ in its ratings.
