Is there a KiCad symbol and footprint for the KA3842ACS?
Yes. The symbol is EasyEDA_Cloud:UC2844G-S08-R 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 KA3842ACS?
DIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the KA3842ACS datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the KA3842ACS?
JLCPCB lists it as part C3094703, with 0 in stock; the sellers' links on this page open their listings.
What can replace the KA3842ACS?
Parts like it in the library: the UC3843BN by STMicroelectronics, the VIPER22A by Minos, the UC3845BN by STMicroelectronics and the VIPER12ADIP-E by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
