Overview
The LM393P is a comparator made by Texas Instruments in a PDIP-8 package with 8 pins. -18V~-2V、2V~18V 0℃~+70℃ 1.3us 2 25nA 2V~36V 2mV 36V 400uA 5nA ESD protection Open-drain TTL、CMOS PDIP-8 Comparators ROHS.
PCBKit's library has its KiCad symbol (Comparator:LM393, from KiCad's library) and its footprint (Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. 4,198 are in stock at JLCPCB (part C5209). 12 open-source boards in 9 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the LM393P?
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 LM393P?
PDIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM393P datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM393P?
JLCPCB lists it as part C5209, with 4,198 in stock; the sellers' links on this page open their listings.
What can replace the LM393P?
Parts like it in the library: the LM311N/NOPB by Texas Instruments, the LM393N(XBLW) by XBLW, the LM2903P by Texas Instruments and the LM393GN by HTC Korea TAEJIN Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM393P?
12 boards in 9 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
