lT1431

Hi, can you specify the LT1431 product you purchased? Such as "LT1431CN8#PBF", for example.

Thanks.

this is the product code LT1431MPS8#PBF that I provided through the approved supplier

The ordered product is correct but does not match the marking information specified in the datasheet.
Datasheet marking: LT1431
Product marking : 1431

Is the LT indicated on the part marking the manufacturer's logo?
If it is a logo, how can we tell the difference between the two marked products?

It looks like the product markings on these two do not have "LT" in them, just "1431".

The product marking of "1431" is correct, and is the expected top marking for LT1431MPS8#PBF

Regarding MPS8 vs CS8, the two both have the top marking of "1431". To differentiate them, the packaging/labelling that the parts were shipped in should be used.

thank you for your information and support, we have resolved the issue thanks to you
