Questions
Is there a KiCad symbol and footprint for the ATTINY426-MU?
Yes. The symbol is MCU_Microchip_ATtiny:ATtiny426-M and the footprint Package_DFN_QFN:VQFN-20-1EP_3x3mm_P0.4mm_EP1.7x1.7mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ATTINY426-MU?
VQFN-20(3x3), with 21 pins. Its footprint is drawn on this page.
Where is the ATTINY426-MU datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the ATTINY426-MU?
JLCPCB lists it as part C3216897, with 45 in stock; the sellers' links on this page open their listings.
What can replace the ATTINY426-MU?
Parts like it in the library: the ATTINY816-MN by Microchip Technology, the ATTINY416-MN by Microchip Technology, the ATTINY1616-MF by Microchip Technology and the ATTINY1606-MN by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
