Questions

Is there a KiCad symbol and footprint for the IRF843?

Yes. the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the IRF843?

TO-220, with 5 pins. Its footprint is drawn on this page.

Where is the IRF843 datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the IRF843?

JLCPCB lists it as part C3290244, with 0 in stock; the sellers' links on this page open their listings.

What can replace the IRF843?

Parts like it in the library: the FDP20N50F by onsemi, the STP34NM60N by STMicroelectronics, the NCE65T180 by Wuxi NCE Power Semiconductor and the IPP60R190C6 by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
