Is there a KiCad symbol and footprint for the RPI-0125B?
Yes. The symbol is EasyEDA_Cloud:RPI-0125B and the footprint EasyEDA_Cloud:OPTO-SMD_RPI-0125B, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the RPI-0125B?
SMD, with 4 pins. Its footprint is drawn on this page.
Where is the RPI-0125B datasheet?
ROHM Semiconductor publishes it: the Datasheet link on this page opens it.
Where can I order the RPI-0125B?
JLCPCB lists it as part C2924220, with 0 in stock; the sellers' links on this page open their listings.
What can replace the RPI-0125B?
Parts like it in the library: the RPI-0125 by ROHM Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
