Compatibility & sourcing notes
The STM32F405 is the STM32F407 variant without FSMC; since the GD32F407 maps to the STM32F407, it covers F405 designs (which by definition don’t use FSMC). A cross-vendor swap still needs a firmware port (clock setup, peripheral library) and board re-validation — a functional alternative.
A functional alternative requiring design-in: pinout and driver may differ — re-validate with the corresponding development resources before production.
