Questions

Is there a KiCad symbol and footprint for the ATTINY402-SSN?

Yes. The symbol is MCU_Microchip_ATtiny:ATtiny402-SS 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 ATTINY402-SSN?

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

Where is the ATTINY402-SSN datasheet?

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

Where can I order the ATTINY402-SSN?

JLCPCB lists it as part C616056, with 1,896 in stock; the sellers' links on this page open their listings.

What can replace the ATTINY402-SSN?

Parts like it in the library: the ATTINY13A-SSU by Microchip Technology, the PIC12F1822-I/SN by Microchip Technology, the ATTINY202-SSN by Microchip Technology and the PIC12F675-I/SN by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
