Questions

Is there a KiCad symbol and footprint for the MSD42SW?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2E_3C and the footprint Package_TO_SOT_SMD:SOT-323_SC-70, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MSD42SW?

SC-70, with 3 pins. Its footprint is drawn on this page.

Where is the MSD42SW datasheet?

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

Where can I order the MSD42SW?

JLCPCB lists it as part C891779, with 878 in stock; the sellers' links on this page open their listings.

What can replace the MSD42SW?

Parts like it in the library: the SS8050 by Jiangsu Changjing Electronics Technology (CJ), the MMBT3904W by GOODWORK, the SS8050W-H by hongjiacheng and the MMST3904 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
