Compatibility & sourcing notes
The KSZ8081 and DM9162 are both standard 10/100 PHYs managed over IEEE 802.3 clause-22 MDIO, so a generic MAC driver reads the standard registers the same way. But the KSZ8081 is RMII-only in a 24/32-pin QFN with a different pinout and Micrel/Microchip vendor registers, so a re-layout and PHY driver/strap review are required — not pin-compatible. Use the RMII-capable DM9162.
A functional alternative requiring design-in: pinout and driver may differ — re-validate with the corresponding development resources before production.
