The symbol is Isolator:PC817 and the footprint Package_DIP:DIP-4_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
SMD-4P, with 4 pins. Its footprint is drawn on this page.
SHARP publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C66405, with 232,702 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the PC817C by GOODWORK, the EL817S1(C)(TU)-F by Everlight Electronics, the PC817C-S by UMW and the EL817(B)-F by Everlight Electronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
