Is there a KiCad symbol and footprint for the OP293B?
Yes. The symbol is EasyEDA_Cloud:BYG20G-E3_TR3 and the footprint Package_TO_SOT_THT:TO-18-2, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the OP293B?
TO-18-2, with 2 pins. Its footprint is drawn on this page.
Where is the OP293B datasheet?
OPTEK publishes it: the Datasheet link on this page opens it.
Where can I order the OP293B?
JLCPCB lists it as part C6943640, with 0 in stock; the sellers' links on this page open their listings.
What can replace the OP293B?
Parts like it in the library: the MTE8600W by Marktech Optoelectronics, the OP290A by OPTEK, the OP290B by OPTEK and the OP292A by OPTEK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the OP293B?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
