So, I bought some C3675 and A1486 from utsource, after seeing that they have it in stock in cheaper prices than bdent, and that this particular distributor seem legit from comments on diya.
I initially thought that all of these are fakes because of the uneven epoxy coating on the back side of the a1486 part; but measuring them gives me a minimum hFe of 30, a maximum of 67, while most of them have a reading about 60.
Similarly, most of the C3675 I got have a hFe reading around 58-71.
So both of these devices are within tolerance. Are there any reasons why I should not be using these devices?
