hello all,
I have a question about IDT product which part number is 9DB433AGLFT.
The first lind of the marking is GR20858 while the secend line is 2117.
Is it a normal marking of this chip？
In addition, they have a different x-ray image when another marking is "GR20549PY 2113".
Thank you for reading my message and give me a help.
Have a nice day!
Hi peter,
From what I have read before "GR" is an assembly location code followed by date and trace code. The 4-digit number is a serial number. Where did you get the chip from?

hi herald,
According to the label,I think the 4-digit number is information about date code .
In this case,the 2117 refers to yr 2021 wk 17.
In fact,my question is the first line marking of the chip.
There are two kind of marking ,one is "GR20858" while another is "GR20549PY ".
At the mean time,the x-ray pictures is also differently.
But I can't find any document to explain the marking of 9DB433AGLFT.
Both of marking meet the rules?
I'm not sure about the source of chip now,so I want to get a help from you firstly.
Thank you for reading my message and have a nice day
Hi Peter,
Yes. I can't find a document released regarding this matter. All I know is that GR is the location code for manufacturing of the chips. If you want more info about this, I think its better to send an inquiry to the technical team to support you better.
