Is there a KiCad symbol and footprint for the BL817B?
Yes. The symbol is EasyEDA_Cloud:TLP291(GB,E and the footprint Package_DIP:DIP-4_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BL817B?
DIP-4, with 4 pins. Its footprint is drawn on this page.
Where is the BL817B datasheet?
Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BL817B?
JLCPCB lists it as part C393570, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BL817B?
Parts like it in the library: the FOD852300 by onsemi, the TCET1102G by Vishay Intertechnology, the FOD814300 by onsemi and the FOD814300W by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
