Is there a KiCad symbol and footprint for the LM311D?
Yes. The symbol is Comparator:LM311 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM311D?
SO-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM311D datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LM311D?
JLCPCB lists it as part C2972032, with 1,136 in stock; the sellers' links on this page open their listings.
What can replace the LM311D?
Parts like it in the library: the LM393D by onsemi, the LM393BID by Texas Instruments, the LM393DT by STMicroelectronics and the LM2903BID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
