Is there a KiCad symbol and footprint for the PL8405?
Yes. The symbol is EasyEDA_Cloud:PL8405Q and the footprint EasyEDA_Cloud:QFN-48_L6.0-W6.0-P0.40-TL_PL8405, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PL8405?
QFN-48(6x6), with 51 pins. Its footprint is drawn on this page.
Where is the PL8405 datasheet?
POWLICON publishes it: the Datasheet link on this page opens it.
Where can I order the PL8405?
JLCPCB lists it as part C782012, with 0 in stock; the sellers' links on this page open their listings.
What can replace the PL8405?
Parts like it in the library: the PL9405 by POWLICON. Check their datasheets: a part that fits the footprint may still differ in its ratings.
