Questions

Is there a KiCad symbol and footprint for the LM393N?

Yes. The symbol is Comparator:LM393 and the footprint Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM393N?

PDIP-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM393N datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM393N?

JLCPCB lists it as part C2873040, with 1,135 in stock; the sellers' links on this page open their listings.

What can replace the LM393N?

Parts like it in the library: the LM393P by Texas Instruments, the LM311N/NOPB by Texas Instruments, the LM393N(XBLW) by XBLW and the LM2903P by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
