Questions
Is there a KiCad symbol and footprint for the LAN8740AI-EN?
Yes. The symbol is Celestial_Network:MICROCHIP LAN8740A and the footprint EasyEDA_Cloud:QFN-32_L5.0-W5.0-P0.50-BL-EP3.4, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LAN8740AI-EN?
QFN-32-EP(5x5), with 33 pins. Its footprint is drawn on this page.
Where is the LAN8740AI-EN datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the LAN8740AI-EN?
JLCPCB lists it as part C150782, with 87 in stock; the sellers' links on this page open their listings.
What can replace the LAN8740AI-EN?
Parts like it in the library: the RTL8201F-VB-CG by Realtek Semicon, the YT8512C by Motorcomm, the KSZ8081RNBCA-TR by Microchip Technology and the SZ18201 by Motorcomm. Check their datasheets: a part that fits the footprint may still differ in its ratings.
