Questions
Is there a KiCad symbol and footprint for the BSS123?
Yes. The symbol is Transistor_FET:BSS123 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 BSS123?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where can I order the BSS123?
JLCPCB lists it as part C53133591, with 2,975 in stock; the sellers' links on this page open their listings.
What can replace the BSS123?
Parts like it in the library: the SI2392ADS-T1-GE3 by ElecSuper, the BSS123 by GOODWORK, the BSS119N by TECH PUBLIC and the IRLML0100TRPBF-ALJ by ALJ. Check their datasheets: a part that fits the footprint may still differ in its ratings.
