Questions
Is there a KiCad symbol and footprint for the CAT24WC128WI?
Yes. the footprint Package_SO:SO-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 CAT24WC128WI?
SOIC-8, with 5 pins. Its footprint is drawn on this page.
Where is the CAT24WC128WI datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the CAT24WC128WI?
JLCPCB lists it as part C7100263, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CAT24WC128WI?
Parts like it in the library: the MAT24C02C-SSHM-T by MSKSEMI, the FEP24C02YSOP8G/TR by Full-Way, the 24LC16BH-I/SN by Microchip Technology and the 24AA02E48-E/SN by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
