OPA2170-Q1: Date code question

Matthew Laing

Part Number: OPA2170-Q1

Tool/software:

Hello,

I had a query regarding the date code of a OPA2170AQDGKRQ1 device. The information we were supplied by Mouser states the date code of the devices we were delivered as 2338.

However when looking at the device the only codes are TI, 39, 2170 on the top of the device and 39A, P13D on the bottom of the device.

The datasheet for the device does not state anything about date codes however it does say 'Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part.'

would you be able to help me ascertain the date code from the information I have provided? 

Thanks

Matthew

    Hi Matthew, 

    Can you show me the image of OPA2170AQDGKRQ1 device or shipping label on the package?

    39A, where 39 is the date code, manufactured at Sept., 2023. I do not know what 2338 is. 

    Best,

    Raymond

    Hello Raymond,

    Please see picture of the device below.

    Unfortunately Mouser have spooled the devices we have off the reel into their own packaging so I couldn't check any of that information against what they were saying the date code was. The delivery paperwork from Mouser states the date code of the devices as 2338. Which would be week 38 of 2023. This would put them at the week commencing September 18 2023.

    This seems to tie in with what you are saying.

    Thank you for your help

    Matthew

    Hi Matthew, 

    I do not know what date code definition Mouser is using. If you have additional questions, please let me know. I assumed that issues are resolved. 

    Best,
