TLC2543: TLC2543IDBRG4HE park marking

Part Number: TLC2543

Tool/software:

Hello,

    We have sold inventory where the customer is questioning the topside marking. They're reporting that part # TLC2543IDBRG4HE has a topside marking of TLC2543Q148KG4C07J. Is that accurate? I've attached a photo of the box label and the topside marking of the part.

    Hi Kevin,

    The top marking (TLC2542Q1) looks correct and matches with the part # (TLC2543IDBRG4HE). I'll follow up with you on whether we can verify the lot trace code. These are older devices, so we might not have this information anymore. I will check on this and circle back.

    Regards,
    Joel

    Hi Kevin,

    We're looking into the lot trace code more in depth. I've asked for help internally to trace it. Can I ask where the suspicion arose from? 

    I will say, the top marking format and layout matches with what is expected.

    Regards,
    Joel
