Questions

Is there a KiCad symbol and footprint for the USB3343-CP?

Yes. The symbol is Interface_USB:USB3343 and the footprint Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.6x2.6mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the USB3343-CP?

QFN-24(4x4), with 25 pins. Its footprint is drawn on this page.

Where is the USB3343-CP datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the USB3343-CP?

JLCPCB lists it as part C633347, with 75 in stock; the sellers' links on this page open their listings.

What can replace the USB3343-CP?

Parts like it in the library: the CP2102N-A02-GQFN24R by Silicon Labs, the CH9102F by WCH (Nanjing Qinheng Microelectronics), the CP2104-F03-GMR by Silicon Labs and the USB3343-CP-TR by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
