LM4040QCEM3-2.5/NOPB, the marking size is different.

Hi, 

The parts that have "R2C" as the top marking is the correct parts (LM4040QCEM3-2.5/NOPB).  The parts with "9C4" and "12T" are not LM4040QCEM3-2.5/NOPB.  

Just to let you know, at ti.com, we have a tool where you can enter the top mark letters.  The link is:

I will get back to you regarding the different font size of the top marking.

thanks! can you advise reason that why same parts are with different size of marking? I mean the parts that have "R2C" . 

Hi Michael,

Let me look into this and get back to you.  Thanks!

Ben

Hi Michael,

Can I ask if these two "R2C" parts came from different reels?  Can you provide me a photos of both reel labels?  Also, are you sure the parts were procured from TI or from an authorized TI Distributor?

Ben 

Hi Michael, 

According to the packaging team, the larger font size was done to help improve the recognition of their vision system inspection.  I hope this answers your question.
