I'm trying to source parts from RS components ( http://rswww.com ) to make this -

http://www.worldtorch.com/boost-kit-instructions.php



But I'm having trouble finding the PN2222 transistor on RS. There seems to be lots of different transistors, and I'm not sure what's what ?



Could one of you kind knowledgeable people give me more details on the transistor, or even take a minute on the RS site and find the part no for me.



Many thanks
 
After reading your post I took time to read the rest of the of the worldtorch site. You have a good point Mr Luther. I don't think they ship internationally. So I've emailed them asking how much extra to post to the UK. Hopefully I'll be able to purchase a few of their kits.
Thanks Lux for making me stop and read.
 
Try 2N4401, 2N3904. You might not get similiar results because the PN2222 is a nice moderate current 600ma NPN transistor with good current gain.

For your boost switching purpose I think the Zetex ZTX650 is a better choice. With a bit of overkill - 2amps of continuous current. :naughty:

The RS UK has the Zetex ZTX450 if you want something less.

Direct Link to the P2N2222A or MPS2222A on RS, it's substitutes for PN2222.
