Apparently, these are in the NEWEST Mouser catalog, which I haven't received yet. The current one expires at the end of July.
The BI Technologies pots LOOK a lot like Alpha's 16mm pots, in the same catalog, and which I have purchased ad nauseum. They have been very good and reliable. However, the rotational life cycle parameter is something to look at.
What is interesting to note is the availability of the hard-to-find 20K and 200K values, and the obvious absence of the common 25K and 250K values. Strange call, if you ask me.
