I use STM32H755ZI to configure the product, but the market is out of stock, can I use STM32H745/STM32H757/STM32H747 instead?
Assuming I'm not using CryptoHash/SFI/SBSFU and MIPI-DSI
Is LQFP144 pin to pin?

Doesn't CubeMX have a "Will-it-Blend" function?
The STM32H745 / H755 will fit. The H743/H753 will also work with a single M7 core, as will the H750
Pretty sure the DSI pins will get in the way. The DataSheets have a pin list, do the due diligence and walk it.
The free stock issue is one of demand vs production capacity. Ladder orders

Hello @Gorden1970 and welcome to the STM32 Community 😊,
Yes, STM32H745 and STM32H755 have the same pinout in their LQFP144 package.
As already mentioned by @Community member, also you should compare the STM32H755 and STM32H745 datasheets to make sure that there are no functional differences.
The LQFP144 package is not available for STM32H747 and STM32H757 MCUs.
I hope this help you!
