Questions

Is there a KiCad symbol and footprint for the BCW31?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2E_3C 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 BCW31?

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

Where is the BCW31 datasheet?

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

Where can I order the BCW31?

JLCPCB lists it as part C549629, with 3,160 in stock; the sellers' links on this page open their listings.

What can replace the BCW31?

Parts like it in the library: the S8050 by hongjiacheng, the SS8050 by hongjiacheng, the MMBT5551 by hongjiacheng and the MMBT5401 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BCW31?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
