Ordering Code Differences
How suffixes on STM32F301 map to package, grade, and reel options.
For STM32F301 sourcing, do not select only by the base series name. Confirm the complete orderable part number, including memory density, package code, temperature grade and packing suffix. For example, C6/C8 and K6/K8 variants may differ in Flash density and package, while TR usually indicates tape-and-reel packing for automated SMT assembly.
How to Choose the Right STM32F301 Microcontrollers
Match the footprint first
Packages here: 32-UFQFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For STM32F301, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "STM32F301" — include the full suffix (e.g. K6U7TR). RFQ with reel/tube preference and required date code.
