I got 2 of these to replace on my Omega Race PS from Mouser, and there is no indicator on the part that says which pin goes to the 'b' location on the board, and which one goes to the 'e'. Do I just go by how the logo is stamped on the part?


EDIT: this is all Mouser gives you:

it should only fit in teh socket one way. The posts are offset from center so if you put it in wrong the screws won't line up to hold it down.

OK cool thanks. From first glance I thought they were in line with one another. There I go assuming again!!
 
Well, by 'offset' I meant to left or right of center which they are.. the posts do not line up on direct center of the part so it's offset.. In surveying terms, a measurable distance perpendicular to center :)

Ah, gotcha. I have a pic I will post of them where it looks to me like they are dead center but hey, I could be wrong.
 
Yes they are offset. Offset is talking about not being dead center. Your pins are off just a small amount, but they are not center. This (Crappy) illistration should help. Not the best picture but was trying to hurry for you.

Thanks- I think I get what you guys are saying now. So then I shouldn't use the ball pein hammer to make everything match up? [/sarchasm]

Oh yes, you should always use a hammer when doing small work around electrical stuff. If it just goes in smooth....then it may come loose. :)
