Questions

Is there a KiCad symbol and footprint for the SC91F72BD20U?

Yes. The symbol is EasyEDA_Cloud:SC91F72BD20U and the footprint Package_DIP:DIP-20_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SC91F72BD20U?

DIP-20, with 20 pins. Its footprint is drawn on this page.

Where is the SC91F72BD20U datasheet?

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

Where can I order the SC91F72BD20U?

JLCPCB lists it as part C221360, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SC91F72BD20U?

Parts like it in the library: the AT89C2051-24PU by Microchip Technology, the AT89C4051-24PU by Microchip Technology, the ATTINY2313A-PU by Microchip Technology and the ATTINY4313-PU by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
