Is there a KiCad symbol and footprint for the 93C46/J?
Yes. The symbol is EasyEDA_Cloud:93C46_J and the footprint EasyEDA_Cloud:PDIP-8_L9.3-W6.4-P2.54-LS7.9-BL-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
Where is the 93C46/J datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the 93C46/J?
JLCPCB lists it as part C6422963, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 93C46/J?
Parts like it in the library: the M24C64-RMN6TP by STMicroelectronics, the 24C02S(XBLW) by XBLW, the M24512-RMN6TP by STMicroelectronics and the AT24C08C-SSHM-T by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
