STM32F030R8T6 pin to pin alternative product

Hello Community. STM32F030R8T6 seems to be unavailable. This is a huge problem. 

Does it exist a pin to pin an alternative (also on other families (STM32F1, F2, f3...).

STM32F030RC is NOT a solution since it appears not to be available too. In any case, I would have the possibility to use this component. On my PCB pins 18,19,47,48 are not connected. Does STM32F030RC works if I don't connect VDD and VSS on these pins?

Thank you.

All VDD/VSS pins need connected.

CubeMX is supposed to be able to show compatible packages, but it seems like they ignore a couple VSS/VDD pairs on that particular chip.

If you're that desperate and only need a few, you could just steal the chip from a Nucleo board:

Thank you very much: i didn't know this function of Cube MX. Fantastic.

STM32F030RCTx is marked as fully compatible even if there are some VDD and VSS differences (18, 19, 47, 48). So maybe the output of tool need to be verified. In any case STM32F051R6T6 seems to be fully compatible: than you very much!!
