Problem with 2SC5171/2SA1930.

[Walkalone]

Hi everybody,

I was bought some famous driver transistors from Mouser, 2SC5171/2SA1930, a few month ago.
But i have a problem, their front text is different. At 2SA1930 is ok, look like types we often saw. And the 2SC5171, the text look a bit little, different with the 2SA1930.
I have same problem, with some 2SC4793/2SA1837.

Are them good? I'm worrying about fakes or other manufacturers, like ISC clone. I don't want use a clone product, original version still available in Mouser.

Thanks,

If you purchased a particular part number From Mouser, and the transistor has that part number printed on it, then those transistors are the correct part. This only means that the factory has changed the machinery that prints the part number.
