Questions

Is there a KiCad symbol and footprint for the STM32H503CBT7?

Yes. The symbol is MCU_ST_STM32H5:STM32H503CBTx and the footprint Package_QFP:LQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STM32H503CBT7?

LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.

Where is the STM32H503CBT7 datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the STM32H503CBT7?

JLCPCB lists it as part C23679795, with 0 in stock; the sellers' links on this page open their listings.

What can replace the STM32H503CBT7?

Parts like it in the library: the AT32F435CGT7 by ARTERY, the STM32H503CBT6 by STMicroelectronics, the AT32F435CMT7 by ARTERY and the STM32H523CCT7 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
