Overview

The BC557B is a bipolar made by onsemi in a TO-92(TO-226) package with 3 pins. -55℃~+150℃ 1 PNP 100mA 100nA 150MHz 180 45V 500mW 5V 650mV PNP Standalone TO-92(TO-226) Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (LibrePCB_Base:BC557, from Librepcb) and its footprint (Package_TO_SOT_THT:TO-92L, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3201656).

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(TO-226), with 3 pins. Its footprint is drawn on this page.

Where is the BC557B datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the BC557B?

JLCPCB lists it as part C3201656, with 0 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.
