Questions

Is there a KiCad symbol and footprint for the SL3420?

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 SL3420?

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

Where is the SL3420 datasheet?

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

Where can I order the SL3420?

JLCPCB lists it as part C50087708, with 1,662 in stock; the sellers' links on this page open their listings.

What can replace the SL3420?

Parts like it in the library: the 6P03 by GOODWORK, the HL3420 by hongjiacheng, the SLMT320V4CPE by Slkor and the SLMT320V6CN by Slkor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
