Questions

Is there a KiCad symbol and footprint for the KA3843ACS?

Yes. The symbol is EasyEDA_Cloud:KA3843ACS and the footprint Package_DIP:DIP-8_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 KA3843ACS?

DIP-8, with 8 pins. Its footprint is drawn on this page.

Where is the KA3843ACS datasheet?

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

Where can I order the KA3843ACS?

JLCPCB lists it as part C3094731, with 0 in stock; the sellers' links on this page open their listings.

What can replace the KA3843ACS?

Parts like it in the library: the UC3843BN by STMicroelectronics, the DK124 by DK, the UC2845BN by onsemi and the UC3845BN by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
