Dear Support,
Please advise if the marking for the traceability date code for MMA9553LR1 is 4 characters only for (Assembly Site, Lot Code and Workweek)
the actual part have only 3 characters which is "BJA", Is this valid traceability for date code?
Please advise if you have any PCN related to markings. Thanks

Hi Vraj,

As far as I know, there is no PCN available, but parts produced in 2014 and later have 3 characters traceability code (third line).

Here is the marking scheme:

*263

9553

YWZ

Best regards,

Tomas
