I've had good service from Jameco over the years but -- I recently ordered
2N5484 FETs from them. The datasheet they have on their site is the same as
Fairchild's, so I figured I would be getting a prime part. If you've used
2N5484s, you know why I wanted that particular part. What they sent,
however, was NTE312s. The Idss spec for the NTE312 is 5-15 mA, vs 1-5 mA for
the 2N5484. I tested a few of the NTE312s and confirmed the bad news. So
beware of Jameco when ordering active parts. You may not get what their
Website and catalog say. In the case of the FETs, in a reasonable quantity,
Mouser has the Fairchild 2N5484s for the same price.
