MOSFET 70T03GJ where to buy?

[wenter]

Hi, all.
I have intel motherboard that was blowing caps. The problem was in a mosfet next to the cap.

The mosfet has 2 lines with info:
line1 - 70T03GJ
line 2 - 618086

Tried to find exact one, but all I found was this datasheet

Please help me find a good replacement for this part. Thanks

This data sheet says that it is an "N-channel Enhancement-mode Power MOSFET". There's got to be a number of compatible alternatives. You might want to call the company (DIGIKEY) and have them look up a common part with the same specs.

Q

[EDIT - Went digging on the shelf and found a ASUS A7VBX-MX mobo that has - 4 - of them on it.

Also has an AMD Duron DHD1600DLV1C 1.6GHz and 256Mb of Infineon DDR333 onboard.

Make me a decent offer on me pulling the transistors and how many, or the whole thing and you handle the pull.

Shipping is from NJ, USA - For USA, figure $10 for the whole board, or $2 for just the transistors.]

if you go to IR (international rectifier)'s site they now have a lookup system.
you put in some other company's part number & it looks up the specs and tells you the best equiv from them.
IR is the most common supplier to the public btw.

@stj - It'd be nice if you'd just give the URL or the search results, which in this case result in no matches.

@wenter -

Let's have some pics of this blown chip, the area where it was, the caps surrounding it, and the board model number.

The motherboard or the MOSFET didn't/don't "blow caps". It is some underlying problem either in the brand and series of caps, or a bad PSU, for instance.

Most likely the other MOSFET of this set is damaged, as they typically operate as a pair. When one fails, the entire load is transferred to the remaining one. Rule of thumb is you replace them as a pair. I am reluctant to sell you (just) one, if you have not repaired the other problems with the board. You'll put it in and it will fail.

In retrospect, my offer to you was premature. I withdraw it for the time being, until this problem can be more carefully examined.

BTW - Please fill in your location in your profile. You don't need GPS coordinates, but a country would be nice though.
