Is there a KiCad symbol and footprint for the LM393PT?
Yes. The symbol is Comparator:LM393 and the footprint Package_SO:TSSOP-8_4.4x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM393PT?
TSSOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM393PT datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LM393PT?
JLCPCB lists it as part C160466, with 3,564 in stock; the sellers' links on this page open their listings.
What can replace the LM393PT?
Parts like it in the library: the LM2903PT by STMicroelectronics, the LM2903PW by Texas Instruments, the LM393PW by Texas Instruments and the LM2903YPT by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
