Thanks, I was looking at RadioShack, and found those 2N1613's and got 2 of them. They have the same collector/emittor values - I just wanted to make sure that I could actually use them. Thanks again!Don't know about 2N3053's, but Mouser has 2N1613's and no minimum order. T0-5 transistors are a bit hard to find. Some of the T0-92 transistors by Zetex are also pretty good equivalents, too. A ZTX652 is good for 60 volts and 2 amps. If the transistor is just a saturated switch, either of these will substitute.
Funny. You are not the first person to complain about Radioshack's poor stock selection.It seems Radioshack has a thing against this general purpose transistor...
For what you're doing, you could just use 2N2222A's.
For that matter, you could use TIP120's - they're NPN Darlington transistors in a TO220 case. Overkill, but with the overkill comes reliability.
Thanks to all of your for your replies. However, it is too late, aa i have ordered the two that i need from Newark. I also got the two relays - all for like $5. However i do have one more question, and maybe it's meant for another section. But i need to be able to plug those regular automotive relays into a socket and have it fit into my breadboard (and eventually a real circuit board if it works). seems that Alliedelec.com is the place to get them. Question is what flavor of 4/5 pin socket do I need?Funny. You are not the first person to complain about Radioshack's poor stock selection.
Happened to check stock on 2N3053's at Skycraft Surplus in Orlando this afternoon - they must have at least a couple hundred of them. They're going for $0.75/ea. Google is your friend, here.
Better off to use a substitute, though - particularly for your application. Why build something with an obsolete part when there's equivalent or better out there?
(said while laying out a PCB for an XR-2206-driven oscillator - yeesh! Well, I've had it for a while... might as well use it.)
