Questions

Is there a KiCad symbol and footprint for the EM346-RT?

Yes. The symbol is EasyEDA_Cloud:EM346-RTR and the footprint EasyEDA_Cloud:HVQFN-48_L7.0-W7.0-P0.50-TL-EP5.4, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the EM346-RT?

QFN-48(7x7), with 49 pins. Its footprint is drawn on this page.

Where is the EM346-RT datasheet?

Silicon Labs publishes it: the Datasheet link on this page opens it.

Where can I order the EM346-RT?

JLCPCB lists it as part C6844984, with 0 in stock; the sellers' links on this page open their listings.

What can replace the EM346-RT?

Parts like it in the library: the CC2652R74T0RGZ by Texas Instruments, the EM341-RT by Silicon Labs, the EM341-RTR by Silicon Labs and the EM342-RT by Silicon Labs. Check their datasheets: a part that fits the footprint may still differ in its ratings.
