Is there a KiCad symbol and footprint for the SD8840?
Yes. The symbol is EasyEDA_Cloud:SD8840 and the footprint EasyEDA_Cloud:SON-10_L3.2-W2.5-P0.70-BL-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SD8840?
SMD3225-10P, with 10 pins. Its footprint is drawn on this page.
Where is the SD8840 datasheet?
WAVE publishes it: the Datasheet link on this page opens it.
Where can I order the SD8840?
JLCPCB lists it as part C41429336, with 61 in stock; the sellers' links on this page open their listings.
What can replace the SD8840?
Parts like it in the library: the X1B000271A005 by Seiko Epson, the SD8801 3225 by WAVE and the SD8830 3225 by WAVE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
