We order the part UC3843N.But there are two kinds of marking codes (02A63VM & 8C3A33LM). Can you help us confirm the date code for the two marking ?

Thank you.

Hi Liuyamei May!

Thank you for reaching out! These two marking codes are different lot tracing codes for this same device. More information on lot tracing codes can be found here.

The first two digits of each code represent the year and month the device was assembled, see the picture below for more details:

Thanks again for getting in touch, I hope this information helps!
