Original question:

TL084M: What are the differences between TL084MJ and TL084MJB

TL084M: Manufacturing Lot

Juan Atanasio Carrasco Mateos

Part Number: TL084M

I want to know the manufacturing lot of three TL084MJ ICs I have in an failed electronic device.

Their identification code are (in all of them):

8CGS 1833A TL084MJ THA

I would like to confirm they have been manufactured after 2018 (or at least after 2015), because some older IC were identified as susceptible of having a corrosion error.

I would be very grateful if you can send me a mail with the requested answer, to jacm@cnat.es.

I have changed some ICs in 2019 because of that issue with the older ICs and I received that info from your side.

Regards and thank you in advance,

Atanasio

    Hi Atanasio,

    Could you elaborate on the issue you've observed with these three units in more detail?

    The identification code you provided indicates a date of mid-2018. To make sure I'm interpreting the rest of the identification code correctly, could you provide a photo of the top marking of one of the units?

    Best Regards,

    Alex Curtis
