We are a rectifier repair house and occasionally come across a component with no logo or part numbers that can be identified. example... we have an 8 pin surface mount that (seems) to act like a comparator and the only number on it is 201. What I am looking for here is a company or organization that we can send parts to, that they can perform tests on in order to identify it.

 

Hello,

Can you make a close up photo of the part?

This may give us some more info about the markings and size.

You may want to pick up one of these:

You will need a Surfboard type adapter to analyze smd chips.

Wow! Thank you for this response. This looks like just what we need. Just when I thought I'd seen it all. Thank you again, tom.

 

Your welcome.

 

I can't get a photo of it. (too small for my camera) It is an 8 pin smd.
No logo or markings other than 201
Thank you all in advance for any insight.
