Questions
Is there a KiCad symbol and footprint for the LM2903N?
Yes. The symbol is Comparator:LM2903 and the footprint Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM2903N?
PDIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM2903N datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM2903N?
JLCPCB lists it as part C2864369, with 79 in stock; the sellers' links on this page open their listings.
What can replace the LM2903N?
Parts like it in the library: the LM393P by Texas Instruments, the LM311N/NOPB by Texas Instruments, the LM393N(XBLW) by XBLW and the LM2903P by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
