Hi Ning,

Are you referring to the "+5" in 2431+5? This refers to the Extended Shelf Life designation.

Thanks,

Patrick

Hi Ning,

If multiple date codes are included in the reel, the earliest date code is printed on the label.

Thanks,

Patrick

Hi Patrick，

Thank you for your reply. The customer still wants to know if the 5 on silk screen represents the year of packaging , and if DC2431 displays the year of wafer?

Hi Ning,

Please see the following document for more clarification: /cfs-file/__key/communityserver-discussions-components-files/196/How-to-identify-STC-_2600_-LTC-_2800_2_2900_.PDF

Are there any units in that reel that are from 2024, indicated by a "4" as the first character in the topside marking?

Thanks,

Patrick
