Overview
The BC858 is a bipolar Transistors BJT made by HT in a SOT-23 package with 3 pins. SOT-23 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BC858, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C692852). 20 open-source boards in 18 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the BC858?
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 BC858?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BC858 datasheet?
HT publishes it: the Datasheet link on this page opens it.
Where can I order the BC858?
JLCPCB lists it as part C692852, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BC858?
Parts like it in the library: the PBSS4140T by Nexperia, the PMBS3906 by Nexperia, the S9012 by Guangdong Hottech and the BC856 by HT. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BC858?
20 boards in 18 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
