i had a transistor in my MSI board which had a hole in it i think its burned or something, its Model is C5001, where can i get one of these or what is a good substitute???
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: help anyone about MSI board
Hi wonder_step!
Seems like you are dealing with an BJT, C5001 is most probably 2SC5001 low Vce(sat) NPN transistor supplying voltage for the memory.
Here's the data sheet:
And luckily I have managed to recover some of the data that was almost totally wiped out from my HDD, found a pdf file and here's a link, check out page 13:
2SC4669 is given as replacement for the 2SC5001 but I would try to find the original or better, hard to say what caused the death of your C5001.

Re: help anyone about MSI board
Well, the 3,3V can deliver quite a big amount of current so even if the linear regulator (2SC5001) is set to 2,5 it will have to dissipate a lot of power if there is a short. Can you see if there is any IC close by the transistor, they might use same controller IC as in the data sheet.
Power that the 2sc5001 has to dissipate is Vin(3,3V)-Vout(2,5V)xIc
Are this transistor shorted?

Re: help anyone about MSI board
nope these transistors werent shorted, my friend just said that this board just died and when he gave it to me i saw that this transistor already had a hole in it....
anyways are there other transistors i can replace other than the 2sc4669 or 2sa1834???
because these components arent available here in my place.....

Re: help anyone about MSI board
can i use these kind of transistors????
Low VCE(sat) Transistor(Strobe flash)
2SD2098 / 2SD2118 / 2SD2097 / 2SD2166
heres the link of its datasheet http://pdf1.alldatasheet.co.kr/datas...M/2SD2098.html

Hi wonder_step!
Seems like the 2SD2118 got same package (CPT3) as 2SC5001 but 2SD2118 has only Ic 5A compared to 10A for the original, I'm not sure how much current a DDR draw someone else on this forum probably know. Think we need to know what kind of controller they use on your motherboard, backtrack from the base of 2SC5001.

Isn't this MSI 845 Ultra (MS-6398) board? I just got one with exactly the same transistor burnt and shorted (maybe someone inserted memory module backwards? or bad design?)
Its base is driven by DRV2 ping of Intersil HIP6501A controller (near ATX power connector). I'll replace the transistor but I'm afraid that the chipset might be fried.

Hi Rainbow!
Have you found where to buy the original or did you find replacement for the 2SC5001?
Hard to say what will happen if the 2SC5001 gets shorted but if the price for the transistor isn't that high just try to replace it.
Cost for the controller IC HIP6501A is around $2 so why not give it a shot?
At least for fun

Re: help anyone about MSI board
Ha, what coincidence!
I shorted that transistor myself on an MSI board (branded Compaq Evo) by stupidly wedging the DDR RAM in the wrong way around.
After some research, I discovered the transistor with a hole to be indeed a 2SC5001R manufactured by Rohm in Japan.
And I have found a local supplier in Germany, Reichelt Elektronik, who still stocks the item. Yay!
I shall be able to report at the end of the week whether I was able to replace the transistor with a crack and a white hole in it with the spare.
I just hope that no other parts got damaged during the burnout.
Cheers.
