Questions

Is there a KiCad symbol and footprint for the AT89C51RC2-3CSUM?

Yes. The symbol is EasyEDA_Cloud:AT89C51RC2-3CSUM and the footprint EasyEDA_Cloud:PDIP-40_L52.3-W13.8-P2.54-LS15.2-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AT89C51RC2-3CSUM?

PDIL-40, with 40 pins. Its footprint is drawn on this page.

Where is the AT89C51RC2-3CSUM datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the AT89C51RC2-3CSUM?

JLCPCB lists it as part C1337575, with 4 in stock; the sellers' links on this page open their listings.

What can replace the AT89C51RC2-3CSUM?

Parts like it in the library: the IA6805E2PDW40IR0 by Analog Devices, the AT80C31X2-3CSUL by Microchip Technology, the AT80C52X2DDF-3CSUM by Microchip Technology and the AT80C52X2DNW-3CSUM by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
