Is there a KiCad symbol and footprint for the ULN2803?
Yes. The symbol is EasyEDA_Cloud:ULN2803A_C5119043 and the footprint Package_SO:SSOP-24_5.3x8.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ULN2803?
SSOP-24, with 24 pins. Its footprint is drawn on this page.
Where is the ULN2803 datasheet?
IDCHIP publishes it: the Datasheet link on this page opens it.
Where can I order the ULN2803?
JLCPCB lists it as part C5359735, with 867 in stock; the sellers' links on this page open their listings.
What can replace the ULN2803?
Parts like it in the library: the GR2803LSS24ARCQ by GR. Check their datasheets: a part that fits the footprint may still differ in its ratings.
