Original question:

DP83826E: Rev0 and Rev1 recognition from IC marking

DP83826E: DP83826E: Rev0 and Rev1 recognition from IC marking

Part Number: DP83826E

Tool/software:

Hi,

It would be great if you could provide us with guidance on interpreting TI IC markings. This would help us verify with our manufacturer and PCBA partner that the correct components are being sourced and assembled.

Once, I asked this question and you explained that we can confirm the part by reading the relevant registers when the boards are available. But when we want to order a new batch of our boards, we are still unsure whether our supplier has provided the correct part. So, it would be very helpful if we could identify the part by its top-side marking as well.

As an example, could you please confirm whether there is any difference between the following two markings, apart from the batch or date codes?

  • 826E TI 168 AEXF G4

  • 826E TI 218 A2VL G4

Thank you in advance for your support.

Armin

    Hello,

    It will be difficult to determine from top marking around 2021-2022 timeframe (first number after TI) what device is Rev0 vs Rev1 without consulting TI for every single order. It can be said that 2023 onward is Rev 1.

    Are these two lots the only lots you are looking to distinguish between?

    Sincerely,

    Gerome

    Hi Gerome,

    Thanks for your reply.

    It would be great if TI had a lookup table showing how to identify whether a part is Rev0 or Rev1 based on the markings.

    Is it correct that all 2023 batches start with the marking “TI 3xy”?

    For this particular order, yes—these two lots are the ones I’d like to check. However, this is the second time we’ve encountered such an issue in our manufacturing, so I’m looking for a more permanent solution.

    According to TI’s website, is the DP83826AE truly a "drop-in replacement"? Would it be a suitable alternative for our EtherCAT application, and does it work without a need for hardware or software modifications?

    Best regards,

    Armin

    Hello,

    Unfortunately, there is some overlap and not a clear cutoff during this specific period of time. 

    DP83826A is a drop-in replacement for DP83826A and would be suitable for EtherCAT application. There are a few quirks that were altered between devices; If in Enhanced mode, I would recommend verifying strapping between devices.

    Sincerely,

    Gerome
