Yes, they do apply in analog use.? They aren't directly applicable,
but they represent the ability of the device to change voltage
level.? A slow switch is going to have a low Ft.? The IRF510 is
literally twice as fast a switch as the IRZ24N ... at least at their
recommended bias conditions.
I worked in the discrete semiconductor industry (engineer, then
business manager) for over 30 years.? Saturation certainly affects
the turn on delay (how hard are you driving it to put it into
saturation) and turn off delay (how hard was it saturated), but it
doesn't significantly affect the rise and fall times as the device
traverses the linear region.
Besides, I was actually asking more about the effect of possible
variations from batch to batch.? The listed specs only give typicals
... and trust me, as an ex-producer of semiconductors I know that
variations can be significant.

Dave,
Ton and Toff do not apply in analog use.? Those are saturated
switch numbers.
Unlike bipolar MOSFETs do not exhibit FT (Frequency where gain
goes to 1)..
They sorta do but the mechanism is different.
For example I've used IRF510s at 70mhz and they are real good at
50mhz.
I see no reason the IRFz24 would be different save for the input C
is greater
so the matching is more critical as you go up in frequency.
