Hi

Q83 is a 2N7002D = mosfet in card reader power circuit

Hi

Q83 is a 2N7002D = mosfet in card reader power circuit

Thanks for the reply, how about the other one below the Q83?

I need to replace those two mosfett, what would i ask or what would write if i will buy those two?

Again thank you sir

Q83 is NOT a 2N7002 ... a 2N7002 is a low-power mosfet, and would not come in that type of SMD package!

Not sure what they are, as the lettering is just barely legible.
Could you read us the letters on Q83 and Q73?

BTW, that part marked 'C28' appears to have a burn mark on it!

The top one is a Si7686 made by Vishay


The bottom one is a FDMS8660 made by Fairchild.


Take note that these MOSFETs have a pad on the bottom, so it will be hard to desolder them.

Did you look at C28? Is it indeed burnt?

Yes sir the nec tokin is burnt and i replaced that with 330 Capacitor

Now my only problem is where will i find that mosfetts. Thanks for the info.

I honestly have no clue, since you don't live in the USA.
Do you know of any electronic component distributors that ship to the Philippines? In the USA we have Mouser and Digikey, but the shipping cost might be high shipping from the US.

Anyways, here is the Si7686 on Mouser:

And here is the FDMS8660 ... oh, according to Mouser it is obsolete! Do you want me to try to find a good replacement for it?

Yes sir, thats the big question i want to ask,

Is theresome kind of way to put a replacement mosfett for those two? And if so do i need to replace as well those two on the left outside of the encircled mosfett coz they are same.


And yes i need to hunt some kind of electronic shop here that supply thos kind of mosfetts, sorry the word mosfett is being abused in this conversation. Lmao.
