Default 2SC5242/2SA1962 fakes...

Hi everybody
My question... Are there any 2SC5242/2SA1962 fakes going around ?
Just asking because I just got a pair of them to repair my Marantz amplifier and they look dodgy, no brand on them and the case of the 2SA is slightly diferent from the original one.
The other thing is that they have exactly the same date code (PMC1120k7)...
Any one of you guys know something about this ?

Regards
Ric

when they are $2-$3 each from digikey, why bother buying from dodgy sources?

You can get 2STC5242 and 2STA1962 from ST Microelectronics. I assume they are clones (not "fake clones", but "good clones") of the aforementioned parts. Very, very cheap and good quality.

According to the Tosh and STM datasheets the STM device performs better.
Higher soa @60Vce 70W vs 150W
Lower Cob 200pF vs 150pF

I'll bet that's just 'specmanship' and the parts are pretty much identical.

Thanks to all.
It is so much easier getting a trait answer to our questions, I never sayed I got them from ebay/online from china/Hong Kong etc.
Got them from a known supplier (online) and were advertised as Toshiba ones.
Second time around got them as Toshiba and they turn out to be from ISC.
Going to compare them with the original Toshiba ones I have and see whats comes out.
