Overview
The BC556B is a bipolar made by DIOTEC in a TO-92 package with 3 pins. -55℃~+150℃ 1 PNP 100mA 150MHz 15nA 200 500mW 5V 650mV 65V PNP TO-92 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BC556, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-92_Inline, from KiCad's library), ready for a KiCad board. 13 are in stock at JLCPCB (part C3201535). 7 open-source boards in 6 repositories on GitHub use it.

Questions
Is there a KiCad symbol and footprint for the BC556B?
Yes. The symbol is Transistor_BJT:BC556 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 BC556B?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the BC556B datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the BC556B?
JLCPCB lists it as part C3201535, with 13 in stock; the sellers' links on this page open their listings.
What can replace the BC556B?
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 BC556B?
7 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
