Is there a KiCad symbol and footprint for the SN74HC161D?
Yes. The symbol is 74xx:74LS161 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN74HC161D?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the SN74HC161D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74HC161D?
JLCPCB lists it as part C6824, with 5,705 in stock; the sellers' links on this page open their listings.
What can replace the SN74HC161D?
Parts like it in the library: the CD4017BM96 by Texas Instruments, the HEF4060BT by Nexperia, the MC14060BD by onsemi and the CD4060BDTR(XBLW) by XBLW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
