    My guess would be it's an oscillator module or maybe a mosfet.

    Having some understanding of the device it's in and what's around in on the board might yield a little more information.

    Well this component is based on a Macbook pro retina laptop, one of these has exploded after a liquid damage. and there are too many to be an osc lol

    Yep, they're more likely to be power mosfets, especially as they're close to inductors and diodes.

    Do they all have the same part number?

    Metal can MOSFETs. That's what they are. Steve your right and the big square things are most likely 0.36uH inductors

    It seems that all of them in that area have the same number except the one that concerns me which is "1010 CDZM 1244".

    does it make sense to you ?

    Yeah, and on closer inspection that's an International Rectifier symbol on the first line.

    IRF1014?

    If so, I can't find any datasheet.

    edit: IRF1010? And the rest would be date code and assorted ephemera (perhaps)

    datasheet (but note it's not in the same package and I would consider it only speculation at the moment.

    Thanks guys for your help, I will post any links or datasheets as soon as I find it for your info ;)

    A least I have a starting point :)

    Looks like their MEDCAN or SMALLCAN. It might be a special because I can only find that package in the directFET range.

    By any chance do you know how to restore faded ids on these type of components ?

    They may not be faded, they may be deliberately defaced to ensure you can't replace them yourself.

    After a good afternoon searching for this device , I found that its reference designator is Q7510 and it is an IRF6802SDTRPBF MOSFET 25V Dual Control FET

    Are you sure? The pad layout looks different. datasheet

    How did you come to the conclusion it was this part?

    It might be worthwhile reading the resistance between the pairs of pads at each end to confirm that they are shorted.

    Also the FET had burn marks around it and it physically looks damaged
