Is there a KiCad symbol and footprint for the LM139DT?
Yes. The symbol is EasyEDA_Cloud:LM139DT and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM139DT?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the LM139DT datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LM139DT?
JLCPCB lists it as part C99438, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM139DT?
Parts like it in the library: the LM339D by Texas Instruments, the LM339DT by STMicroelectronics, the LM239D by Texas Instruments and the LM339 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
