Dear Sir/Madam
We have two samples of TPS71730DCKR,but we found the marking are different,have two kind of marking,pls check attached picture.
Can you tell me which one is correct or both marking are available of this part?
We want to make sure,in case we need more qty in the future so we can accept both.
Pls help to check and advise.
Thank you so much!

Hi Susan,
Did these devices come from the same reel? The dashes above and below "BNA" are binary date codes so those are normal, although I would expect them to be the same if they came from the same reel. The pin 1 marking can be different depending on where they are packaged, and they look normal as far as I can tell, although again if they were in the same reel I would expect them to be the same pin 1 marking.
Regards,
Nick
Dear Nick
They're different reel and Date code,the left one is 2025+ and right one is 2136+.So do you mean both marking are available?
Thank you so much!
Susan
