No, probably not Ian. If you remove the chips you can sometimes tell which pins are used, and which pins serve the same function. For example, your "normal" 4562 and 8858 FETs will work just fine even if you solder some of the output legs together, since they're the same output. Of course, that's not always the case so there's no guarantee.

Does your friend know of any other FETs that share that packaging? I have a hunch that you need a P+N type of FET chip (one of each type bundled into the package) rather than the dual-P FET that is shown in the link you gave me. 4562's and 8858's are P+N type FETs, btw, which is why I'm making this guess.

Hi Brian,

He was able to dig up these two:

http://www.onsemi.com/pub_link/Colla...TGD3149C-D.PDF

http://www.onsemi.com/pub_link/Colla...TGD4167C-D.PDF

They are labeled as 'Complementary N-Channel and P-Channel MOSFET's. Is that what you meant in your last post? Any thoughts on the suitability of these two?

Thanks again,

ianc

hello guys, i am having the same issue with my board, and was wondering if these were confirmed to be the correct ones?
thanks
Chuck

Sorry for not getting back to you sooner, Ian, but I think that these are the right type of chip. Complimentary N/P FETs are the ones typically used to drive motors (if you recall, the AM Mini-Z boards used a pair of 3004's to drive the servo motor). I have no way to confirm that it's correct other than ordering a few sample FETs of both of the ones you've found, and trying to stick them on the board. You could also check the dimensions of the FET footprint that are listed at the bottom of those two PDFs, and compare to the pads on your ASF board.

I just had a board that had that also burned one of the servo fet's. So would like to update you guys on my findings.

So far i have managed to identify the pins on the original steering fet's, and managed to use a 3004 mosfet to get the steering working again. So it's confirmed that q9 and q8 are complementary n/p mosfets.


I can't remember the pins exactly, but looking at the high definition pics ianc posted this is what i can figure out

Pin 1 -
Pin 2 - p-channel gate
Pin 3 -
Pin 4 - n-channel source
Pin 5 - n-channel gate
Pin 6 -

So looking at these pins, none of the transistors posted before is a direct replacement.

I can repair this problem if anyone needs a replacement steering FET.

I have limited supply though of the stock style steering FETs.

Just did a quick search around for some possible replacement transistors.

http://www.vishay.com/docs/71963/71963.pdf
http://www.vishay.com/docs/71168/si1016x.pdf

The difference between these 2 is the package. I don't have any board near me at this time, but if anyone can just measure the pads and the size of the transistor and we might just have found a replacement

Can anybody recommend a source for a replacement for this part? Here's hoping...

Thanks for the help,

ianc
Same thing happens to me yesterday!! Did somebody find a replacement?

Thanks in advance!

Alberto has found two candidates above -- even if they're not exactly the OEM chip, as long as the specifications are good then they should be OK as a replacement.

As soon as I get back from my trip I can measure the steering FETs on my 02 ASF board. I think we all kinda forgot about this for a bit, heh.

Ciao Brian,

Thanks for the answer :-)
I think both of the ones Alberto found are too small, the biggest one is 2.0mm and the fet's on the board looks 2.5 or 3.0mm...

In the mean time, following the suggestion made by Alberto about using the same "standard" fet's, I follow the schemes on the datasheets and here is the results (image attached) Do you think is possible to put together all the ouputs (pins 3 and 6) as on the "standard" fet?

Regards!

I think i've found the right size: SuperSOT or TSOP package. It's 3mm x 2.85mm big.

What about the Fairchild FDC6327C? http://www.fairchildsemi.com/ds/FD/FDC6327C.pdf

And the Vishay SI3586DV? http://www.vishay.com/docs/72310/si3586dv.pdf

Thanks

Hey guys,
A friend of me has the same problem. Via google I came to this thread (although I know the forum very well ).
If the FDC6321 is a good candidate, you can find them here: http://www.mikromodellbau.de/Shop/ar...ls.php?aid=724

I have an order pending there, will ask if he can add one for test and let you know of course.

Grtz

Thanks Haco,

Will be interested to learn if you find out anything,

I see we have a few candidates in this thread, but has anyone been able to use one of them for a successful repair?

I have only tried with direct replacement from parts boards and it works. Maybe I will order some of these and give it a shot if no one else has any updates.
