Questions

Is there a KiCad symbol and footprint for the LM2903DT?

Yes. The symbol is Comparator:LM2903 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 LM2903DT?

SO-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM2903DT datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the LM2903DT?

JLCPCB lists it as part C98194, with 13,204 in stock; the sellers' links on this page open their listings.

What can replace the LM2903DT?

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.

Which open-source boards use the LM2903DT?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
