Part Number: TL082

Hi, everyone.this is Summer from Union Components . 

recently ,I got a TI part TL082CP,but the leadframes looks like oxidized. like the picture below. 

So I find another reliable supplier to take this part, their parts doesn't looked like oxidized.pls check the picture below,

They are both DC 18+,so I am confused, does it means some parts are using non-rough leadframes and some are rough leadframes?

and there are some differiences on the top of marks (the typeface ,and the typesetting...)

anyone knows why ? do you encounter the same confusing ?

pls kindly let me know. thanks a lot.

  • Hi User,

    The appearance difference could be roughened leadframe, but let me look into the specifics for this part and get back to you.

    Best,
    Paul

    Hi Summer,

    This device was recently changed to a roughened lead-frame, which explains the slight oxidized appearance. There are no differences in electrical performance.
