I just noticed something. Do you mean MPSA14 or MPSA13? The datasheet you posted is for MPSA13 and thats what ive been reading. The order code you posted is for MPSA14 though. In the datasheet for the MPSA14 it says Ic is 1.2A. The datasheet ive been looking at says that Ic means collector current and that one is only 500mA. Both look suitable to me except the MPSA13 is a little cheaper.

Hi,The datasheet you posted is for MPSA13 and thats what ive been reading.
The order code you posted is for MPSA14 though.
The datasheet I have posted is the datasheet of the MPSA13 and the MPSA14.
http://www.rapidonline.com/netalogue/specs/81-0142.pdf
The first page of the datasheet is added by Rapid. If you scroll to page 2
you will see the real page 1 of the datasheet and on the top right corner
you can read MPSA13 and MPSA14.
The collector current for the MPSA13 and the MPSA14 is 500mA.
The difference is the current gain.
Time to build a prototype, try both transistors.
Best regards,

Im not sure which link im looking at then. The one i got using the order code from your schematic looks completely different. It has chinese in it. http://www.rapidonline.com/netalogue/specs/47-5512.pdf. Thats the one i got the 1.2A from. I guess getting both cant hurt because the bigger versions of these lights will have more LEDs so i guess its worth testing both

Hi,
Will be the transitor better than the baby milk?

Ok, so china has contaminated milk powder. Are you saying not to trust the transistor with chinese in the datasheet incase its substandard or did i completely miss the point?
"Will be the transitor better than the baby milk?"
Erm, i guess it will be because i dont think baby milk will turn LEDs on

Are you sure that's chinese? Or is it a manufacturer's logo?Originally Posted by The Master

Im not sure exactly. It could be japanese kanji. The datasheet Luciano linked to didnt have any of that. It says its for both but the second one has a completely different datasheet. Now the datasheets from www.fairchildsemi.com are completely different to both of them :O

Hi,
If the quality of the datasheet reflects the quality of the product....
http://www.rapidonline.com/netalogue/specs/47-5512.pdf
Compare the above datasheet with the datasheet of the MPSA14 made by Philips Semiconductors.

Make sure you know who are the makers of the components you use.

That makes sense.
So can you get the same component (with the same number) from more than one company then? I thought each company had their own numbering system even if they make components that do the exact same thing
