    Hi Jerick,

    Thanks for your question and welcome to the forum!

    Yes, those numbers identify when the device was made and the lot it is from.

    Just to be absolutely sure, do you have the full part number?  It will look like the orderable part number online.

    Regards,

    Daniel

    Hi Jerrick,

    Yes, this is correct then.  The part should be from December 2018.  I suppose December 2008 is also possible, but I'm guessing 2018 is more likely.

    Regards,

    Daniel
