type of transistor used at hard drive thermal sensor inside iMac a1224
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.
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.
Is this a good question?
