TO92 Plastic Pinouts

[pete.a]

Im just in the process of de bugging some old projects , but need some guidance with the following parts. Are the pinouts different on these small signal transistors.
BC184 L and 214 L
Can't find them in my book ..only goes from A to H
PLus some other transistors that have been used are BC 546 and BC556 with the letter B after the number . Would i be right in thinking that any such letter after the number signifies the pin outs, and if no letter is present how do know if its an TO92A , B or C package.
Having looked at the circiut drawing's all transistors need to be C-B-E , which going by my book indicates TO92 C package.

Pete.

bc usually come cbe left to right.
bc...L are usually ecb. = 2sa/2sc
mpsa, 2n, Eline are usually ebc.
But check the data sheet, usually worth putting a diode test on as well.

Hi Pete

Check the online bible on:
www.alldatasheet.com
Your transistors can be found there

The letter after the part name (e.g. B in your case) specify the Hfe range of the component. You can see it on the datasheet.

Thanks for the info guys . Id forgotten about the on line bible , plus its been some time since i last dabbled with electronics . Raising the two boys take's up all of my time , at present . So my hobby is on the back burner for awhile .
