It looks like the board accommodates different pot pin layouts. 3 pins aligned or 3 pin triangle like the 3386k. I have used the 3296Ws - it seems like it would work with the flexible layout - here is the 2k part.

652-3296W-1-202LF

Yes, I have specced the 3296W pots for the 25 turn variants.

3299 are better pots, IMO.

Could you elaborate on what makes them better?

I have compared the 2, and the only specced difference I can see is that the 3299 is specced to handle up 125 degrees C while the 3296 is specced to 150 degrees C. But I will add it as another option on the list.

I also see that for the 3299 series they spec the Number Of Turns as Multi-Turn, while the 3296 is specced as 25. What does that actually mean?

3299 added as an option.

I believe the wiper on the 3299 is a little heaver, maybe a double. Just more duarble part. Difference in price is minimal, in the schem of things. Unimportant if you plan on replacing with fixed resistor.

I agree that the price difference is irrelevant. We just need to make sure it fits since the 3299 is larger: 3/8" square vs. 1/4" square for the 3296.

didnt realize it was that tight. 3296 is fine.

Actually, I think both will be fine. I have scaled the PCB on my PC screen and I believe the 3299 will fit.
