type of transistor used at hard drive thermal sensor inside iMac a1224
Hello everyone's
Please answered somebody who know what type of transistors used in thermal sensors inside iMac a1224 a1225 mid2007-early2008.
I know that is exactly the transistor but what transistor?
I have not one of this thermal sensor at hands for check the transistor mark, but I need to know for built it by myself.
Thanks and regards.

I think that the 2n3904 bipolar transistor was used. It costs in ma local shop 5 cents.
Cable costs nothing for me.
Connector - maybe 20cents.
And my own work)) I'll pay myself.
It so cheap for me. And I can do it for 15 min. Most cheapest original thermal sensor on eBay - 5.80$ plus the time that I will wait the parcel. I live outside from Noth America . Or 5 cents and 20 cents plus 15 min of my own time with solder station in hands.
I just want to clarify what kind of transistor it is.

Well
In the end, I found good quality photos in description of one of the lot on eBay. Transistor marking is clearly visible on one of the photos. It's Mps3904 - npn bipolar transistor. It can be replaced by 2n3904, 2n4401 etc
so, if you are have enough experience in soldering, you can easily produced that thermal sensor by yourself, I think it takes something about 15 to 30 minutes. And you can save 7$ per item and shipping costs if you are far from seller destination.

One year later
Two thermal sensors which were soldered of 0,1$ transistors 2n3904 and wire works just fine.
Es esta una buena pregunta?
