    Pls help identify this toasted componet on an AGP card.

    I have a faulty CANICON 1000mF 6.3V cap on this card, "MilkyWay" GF4Ti4200 128MB AGP Card, with a burnt component.

    I can't find a matched part at local shops, anyone can suggest an alternative or replacement part?

      It MIGHT (and also might not) be the same as the one next to it.

        i was looking at a few designs. looks most similar to the msi. i think it is the same as the unit next to it.



        what to do?

        - find someone with the same card and get them to read what is written on their fet. (might be difficult, it is an off brand which i have not heard of before.

        - replace with the same fet or similar specs as the unit next to it and pray.

        ??

        pegasus, is there two the same at the other end of the board?

          the FET above toasted one appears to be an ON Semiconductor part. I've heard of this brand, they're in the Digikey catalog.

            That's one strange looking AGP card.

              I can't tell from original damaged FET because it is incomplete and all marks just gone.

              Will a simply transplant of FETs from other spoilted GF4 cards fix this? Perhaps I have better luck if I replace a pair?

              It is a card friend bought from HK. I don't think I can get another one for reference now.

                possibly. Pls post a pic of the entire card.

                  On Semiconductor was formed when Motorola spun off their discretes and low profit ICs (older linear ICs, 4000- and 4500- series CMOS, etc.).

                    I did a search on their website for "*D30*", and when I looked at the datasheet, the markings (other than the date code) corresponded to a D30N02 https://cdn.badcaps-static.com/pdfs/...a54062dbb1.pdf
