Compatibility & sourcing notes
The LAN8742A is the very common default STM32 (H7/F7 Nucleo) PHY, RMII-only in a 24-pin SQFN. Like the DM9162 it is clause-22 MDIO-managed and interchangeable behind the same MAC, but its pinout and vendor registers differ — a re-layout and PHY init change are needed; both being RMII does not make it pin-compatible, so it is a design-in alternative.
A functional alternative requiring design-in: pinout and driver may differ — re-validate with the corresponding development resources before production.
