    Hello Jun,

    Top line is just the part identifier.  Second line gives year, month, and site in the first, second, and third characters respectively.  It looks like your part is from April of 2015.  Third line gives lot information.

    Do you have concerns about part authenticity?

    Regards,

    Daniel
