Im putting a circuit together that calls for a BC182L and I have a few questions.
1) Where can I find these transistors?
2) What does the "L" mean?
3) What could I sub for a BC182L?
Hello,
1) I bought some of them at eBay, they are from Fairchild...
2) Maybe it stands for a hFe-value, I don't know exactly...
3) Try other NPN bipolar-transistors...
Greetings
Magnus
You can buy here:

You can view the datasheet here;

I have some BC182B's & I can't see any difference in the datasheets except the pin layout and the BC182B doesn't show the Hfe for 2mA! ???
ABC at the end usually means low medium and high, but L I don't know.
Btw alldatasheets is a good site for datasheets, I look up any compents I'm using. It might not have all the data you need but it usually shows the main characteristics.

The "L" indicates an ECB pinout.
I am not 100% sure , but I seem to remember that a 182L is the same as a 182B but with the E and B leads reversed - so ECB , not EBC.
Im having trouble reading the data sheets.
Should I be looking at the small signal hfe?
What other transistors would be similar to the BC182L?
> Should I be looking at the small signal hfe?
Depends on what "circuit" you are putting together.
Some need specific breakdown voltage. Some need a minimum hFE. A few won't tolerate a too-high hFe. Some chores need low Ico at high temperature. Some circuits expect a transistor to match to some other part. 9V noise-generators require a 7V emitter breakdown....

Without knowing what you are doing, try 2N3904. Be sure of the pinout, it seems to be different.

BC182A and BC182B :)
IIRC, BC184 will do pretty well anything a 182 will.
