Is there a KiCad symbol and footprint for the BL817S?
Yes. The symbol is EasyEDA_Cloud:TLP291(GB,E and the footprint EasyEDA_Cloud:SOP-4_L6.5-W4.6-P2.54-LS10.2-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BL817S?
SOP-4-2.54mm, with 4 pins. Its footprint is drawn on this page.
Where is the BL817S datasheet?
Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BL817S?
JLCPCB lists it as part C393569, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BL817S?
Parts like it in the library: the TD814(SL)(T1)-G by LIGHTNING, the FX814AVBTH-T1P1GW by LYG, the FX817CVBTH-T1P1GB by LYG and the TD814A(SL)(T1)-G by LIGHTNING. Check their datasheets: a part that fits the footprint may still differ in its ratings.
