Questions

Is there a KiCad symbol and footprint for the KSZ8081RNACA?

Yes. The symbol is Interface_Ethernet:KSZ8081RNA 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 KSZ8081RNACA?

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

Where is the KSZ8081RNACA datasheet?

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

Where can I order the KSZ8081RNACA?

JLCPCB lists it as part C633270, with 21 in stock; the sellers' links on this page open their listings.

What can replace the KSZ8081RNACA?

Parts like it in the library: the KSZ8081RNACA-TR by Microchip Technology, the KSZ8081RNAIA-TR by Microchip Technology, the KSZ8081RNDCA-TR by Microchip Technology and the KSZ8081RNDIA-TR by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
