Hi Team,

Could you tell me the difference between red part and blue part?
I would also like to know why these part names are completely different.



Best Regards,
Yaita

    Hi Yaita,

    Thanks for reaching out! Just to clarify, the TPS3803-01QDCKRQ1 is the same as the 2T03-01QDCKRQ1 from a form, fit, and function perspective. The same can be said for 2T03G15QDCKRQ1 and TPS3803G15QDCKRQ1. The 2T03 (G4) parts were created as lead free variants back when the TPS3803 was still leaded. Today the TPS3803 is also lead free so both parts are identical.

    Hope this clarifies any doubts you had, if not let me know how else to help.
