The silicon, package, and electrical specifications are identical. The TR variant is intended for automated assembly lines that feed from reels."},{"question":"Can STM32L031C6U6TR be used as a replacement for STM32L031C6U6?","answer":"Yes — the STM32L031C6U6TR is functionally identical to the STM32L031C6U6. The only difference is the shipping medium (Tape & Reel vs. tray/tube). If your assembly process accepts reels, it is a direct drop-in replacement."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L031C6U6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L031C6U6TR when reusing this data.
