Is there a KiCad symbol and footprint for the LM231N?
Yes. The symbol is Analog:LM231N and the footprint Package_DIP:DIP-8_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM231N?
PDIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM231N datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM231N?
JLCPCB lists it as part C179099, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM231N?
Parts like it in the library: the LM331N/NOPB by Texas Instruments, the XD331 by XINLUDA, the LM231AN by Texas Instruments and the XD231 by XINLUDA. Check their datasheets: a part that fits the footprint may still differ in its ratings.
