Applications
STM32G431KBU3 is an STMicroelectronics STM32-class microcontroller used in industrial control, consumer electronics, motor drivers, USB devices, and OEM/EMS controller boards. Typical designs lock the UFQFPN32 footprint, Flash/SRAM size, and peripheral set. Confirm the full ordering code against the ST datasheet before swapping nearby STM32G431 suffixes.
Procurement notes
Confirm the full ordering code, package (UFQFPN32), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.

FAQ
Where to buy STM32G431KBU3?
You can request STM32G431KBU3 from SJ Chip via the RFQ form on this page or the site-wide RFQ. We confirm manufacturer (STMicroelectronics), package, quantity, and lead time on the quotation.
Is STM32G431KBU3 available?
Listed inventory shows 71,619 pcs. Lot, date code, and shippable quantity are confirmed on RFQ — treat the listing as availability to quote, not a guaranteed cart ship.
What is the package of STM32G431KBU3?
The sourcing listing shows package UFQFPN32. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.
What are alternatives to STM32G431KBU3?
Potential alternatives include STM32G431KBU6, STM32G431KBT3, STM32G431KBT6TR and other same-series or same-package listings — all require datasheet and pinout checks. These are similar stock for evaluation, not automatic drop-in replacements.
