Is there a KiCad symbol and footprint for the SR3439K?
Yes. The symbol is EasyEDA_Cloud:SR3439K and the footprint Package_TO_SOT_SMD:SOT-563, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SR3439K?
SOT-563, with 6 pins. Its footprint is drawn on this page.
Where is the SR3439K datasheet?
SALLTECH publishes it: the Datasheet link on this page opens it.
Where can I order the SR3439K?
JLCPCB lists it as part C3027173, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SR3439K?
Parts like it in the library: the SRX3134K by SALLTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
