Hello all,

I am looking to identify a component with VC and another with CGK marking.
Their packages look similar and all look to be either SOT-353-1, SOT-25, or SSOP-5?

Can someone please help me identify these components and tell me the difference between the mentioned packages?

Thank you,

Hey all,
I was able to identify the component with the marking 'VC'. It is a logic gate (MC74VHC1GT14) from onsemi and its package is called SC-74A.

That's why we love standards, there are so many of them.
Exactly! I have just found 5 or 6 packages that look the same SOT-353-1, SOT-25, SSOP-5, SC-74A, SC-70-5l, SC-70-5.
Someone might say look at dimensions and pitch .. but in my case, these parts that I am trying to identify are already soldered and located in not-so-roomy places which makes identifying these packages just by looking at them seem impossible XD.
