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!
