Hi Liang,

If they are same part number, then they are the same part.

For other print, may be manufactured by different factory or other information which won't make a difference on function.

Hi Liang,

Please refer to below information.

So it's clear that the second line is the date. The last line is the assembly lot or site code which doesn't make function a difference.

Hi, Ziv,

Our customer IQC consider the two device have many different for the prints, and they wants to know if there are any offical file to explain,

Please kindly provide the below difference result:

1. Why the Pin#1 is the line in the pirture 1 and the spot in pirture;

2. Why the "TI letters" on pirture 1 and pirture 2 are different icon;

3. 12 is mean Feb. 2021 in pirture 1, and 2C is mean Dec. 2022, right?

So please also kindly check if there are any PCN file to provide, thanks.
