Questions

Is there a KiCad symbol and footprint for the C945?

Yes. 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 C945?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the C945 datasheet?

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

Where can I order the C945?

JLCPCB lists it as part C22458944, with 32,495 in stock; the sellers' links on this page open their listings.

What can replace the C945?

Parts like it in the library: the MMBT3904 by hongjiacheng, the S8050 by hongjiacheng, the SS8050 by hongjiacheng and the MMBT5551 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the C945?

11 boards in 10 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
