Part Number: LMV331

Hi TI Team,

We are looking for this Part Number LMV331IDBVR at "Part Marking Lookup".

Per this, the marking for this device LMV331IDBVR should be R1IC or R1II, but we have material with marking R1IF.

Could you please confirm what is the meaning of the "F" or the difference with "C" and "I".

Is the "F" correct for the marking for this device LMV331IDBVR?

I saw in other support that the F is correct, but I do not see the information updated on "Part Marking Lookup", so only I would like to have a double check for it.

It will help us to continue with our process.

Thanks in advance.

I verified that R1IF is valid silicon. It is just from a different fab that we are no longer using and as a result, it got dropped from the part lookup table.

Sorry for the confusion, but you will not experience any difference in performance with this device.

Hi Chuck,

Thanks for your reply!!!

One last question, With "fab" do you mean a different process of fabrication or a different factory location?

Thanks in advance.

Sorry for not being specific. The silicon is from a different factory location but same process.
