How to decode LIS2DU12 QR code marking

Lazaro
Associate II

We have purchased some LIS2DU12 and when scanning the QR code markings we see 78327KT603ES0YJ on some and 78327KT603EO0YZ on others. What is the difference? And how do we decode the QR code, didn't see anything on the datasheet?

Thanks.

The company I work for has ordered 2000 PCBAs which include the component mentioned.

I do not have access to the failures; I've just been tasked with finding out what is the difference if any between the two LIS2DU12 ICs. All I have is the text I got from scanning the QR code and the datasheet doesn't mention what the code means. Is there a difference between the two?

Hi @Lazaro ,

Why do you want to decode it? Which kind of information are you looking for?

I would like to know the difference between the markers. Are they two different parts? One of our PCBAs is working the other is not and the markings are different as described above.

Can you X-Ray and check that it's not some soldering / shorting type issue?

Not Working? At any level, ie unable to query any internal registers.

Pins stuck-at-zero, stuck-at-one.

Registers work, but Not Functional..
