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.
