Questions

Is there a KiCad symbol and footprint for the CAT24C64WI?

Yes. The symbol is EasyEDA_Cloud:MR44V064BMAZAATL and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CAT24C64WI?

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

Where can I order the CAT24C64WI?

JLCPCB lists it as part C5591009, with 0 in stock; the sellers' links on this page open their listings.

What can replace the CAT24C64WI?

Parts like it in the library: the M24C02-WMN6TP by STMicroelectronics, the M24C02-RMN6TP by STMicroelectronics, the 24LC256T-I/SN by Microchip Technology and the CAT24C08WI-GT3 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the CAT24C64WI?

3 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
