Just thought I'd throw this out there, I rolled the dice on these K117, fully expecting fakes.

I tested half of them (25 out of 50) with a Peak DCA75.

Average Vgs(off) = -0.351V

Average Idss = 1.815mA

Standard deviation Vgs(off) = 0.023V

Standard deviation Idss = 0.262mA

Pinout is a match, and obviously they come up N-channel with swappable drain/source in the DCA75.

I tried a couple in both a SS/BS mini clone and a Duende boost with no noticeable change in circuit self noise vs. SMD J201.

So does this mean they're actually real? Well... maybe. I wish I could actually test for noise.
