Questions

Is there a KiCad symbol and footprint for the SC91F73K28U?

Yes. The symbol is EasyEDA_Cloud:SC91F73K28U and the footprint Package_DIP:DIP-28_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 SC91F73K28U?

DIP-28, with 28 pins. Its footprint is drawn on this page.

Where is the SC91F73K28U datasheet?

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

Where can I order the SC91F73K28U?

JLCPCB lists it as part C221370, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SC91F73K28U?

Parts like it in the library: the PIC16C55-10/SP by Microchip Technology, the PIC16C55-10I/P by Microchip Technology, the PIC16C55-10I/SP by Microchip Technology and the PIC16C55-HS/SP by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
