Overview
The LM339J is a comparator made by Texas Instruments in a CDIP-14 package with 14 pins. 0℃~+70℃ 2.5mA 250nA 2V~30V 3mV Open Collector CDIP-14 Comparators ROHS.
PCBKit's library has its KiCad symbol (Comparator:LM339, from KiCad's library) and its footprint (SparkFun-IC-Amplifiers:TSSOP-14, from Eagle libraries), ready for a KiCad board. 3 are in stock at JLCPCB (part C2868509).

Is there a KiCad symbol and footprint for the LM339J?
Yes. The symbol is Comparator:LM339 and the footprint SparkFun-IC-Amplifiers:TSSOP-14, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM339J?
CDIP-14, with 14 pins. Its footprint is drawn on this page.
Where is the LM339J datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM339J?
JLCPCB lists it as part C2868509, with 3 in stock; the sellers' links on this page open their listings.
What can replace the LM339J?
Parts like it in the library: the LM339NSR by Texas Instruments, the LM339FV-E2 by ROHM Semiconductor and the LM339ANSR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
