Is there a KiCad symbol and footprint for the PC3H4A?
Yes. The symbol is Isolator:PC3H4A and the footprint Package_DIP:SMDIP-4_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PC3H4A?
SSOP-4, with 4 pins. Its footprint is drawn on this page.
Where can I order the PC3H4A?
JLCPCB lists it as part C48996490, with 4,995 in stock; the sellers' links on this page open their listings.
What can replace the PC3H4A?
Parts like it in the library: the PC3H4B by AOTE and the PC3H4AJ0001H by Sharp Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
