Hi,

not sure what you want to achieve, but I can confirm that ACEX 1K series used similar marking with YYWW date code, e.g. below 0125.

    Hello!
    Thank you!
    Here is an example: a photo of a component with the date code “1721”.
    In the current marking format, “21” does not appear to be a valid week code.
    Was it common in older marking formats for the production week to be represented by any symbols, such as “21”?

      Hi
      "In the current marking format, “21” does not appear to be a valid week code." What else?

        Hello!
        That’s exactly why I am asking you — the components were discontinued in 2017, while all the current documents about component marking are from around 2019–2020. Could it be that in earlier years the week code format was different?
        Thank you!
