Is there a KiCad symbol and footprint for the LM3302N?
Yes. The symbol is EasyEDA_Cloud:LM239AM_TR and the footprint Package_DIP:DIP-14_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 LM3302N?
PDIP-14, with 14 pins. Its footprint is drawn on this page.
Where is the LM3302N datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM3302N?
JLCPCB lists it as part C2879102, with 1,250 in stock; the sellers' links on this page open their listings.
What can replace the LM3302N?
Parts like it in the library: the LM339N by HGSEMI, the LM239N by HGSEMI, the LM339AN by HGSEMI and the LM319N by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
