I'm in need of a 6.0v, 1A, fixed, TO-220, voltage regulator, it's the voltage regulator for a QSI smoke/headlight circuit.
I have a LM317, which is an adjustable voltage regulator capable of handling 1.5 amps, in a TO-220 package.
Would this be a good substitute?

How about a 7806 in the TO-220 package?
The LM317 needs programming resistors to generate a fixed voltage, so it's not pin compatible.
Order it from MTH. LM78L05 P/N AI-0000050.

I thought he wanted a 6V regulator, not a 5V one. Besides, by the time you pay MTH shipping, you can get it almost anywhere far cheaper.
Oh, I may have mis-understood. I thought it was for a MTH smoke unit.
That should do it John. I figured the LM317 needed something to help set the voltage, just wondering what it would do if no resistor was used in the circuit.
There's a good sized heat sink that goes on the regulator, which I think I have in my parts bin. My Williams/Samhongsa brass 2-8-2 has the same QSI setup and it has the regulator and heat sink.
If you can find the LM340T-6, it's the same part, Mouser was the only place I found it on a quick search.
Thanks John, I'll take a look.
The 7806 is the right part, that's what's on the 8-sided board in the 2-8-2. It was missing from the board on the Weaver 4-6-0 chassis I bought last year, figured the original owner must have had a failure.
