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 can replace the BC556B?
Parts like it in the library: the S8050T by XCH, the DS18B20 by DALLAS MAXIM, the DS18S20 by DALLAS MAXIM and the BC550CTA by FAIRCHILD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
