Need help ordering B10K slide pot Answered

Hello,

I need a replacement Alpha B10K slider pot, 60mm travel, has 2 separate pots in the package.  The one I have which I think is bad has 8 pins, 4 on each end.  So far all the replacements I have found on the web have at most 6 pins, 1 less pin per pot.  1 of the extra 2 pins on my pot are being used in the circuit (a USB music player).  Can I adapt the 6-pin pots to work in my device, or can someone direct me to where I can find a B10K with 8 pins?

Any help appreciated.

Thanks

If it's not on the company website, the part is either obsolete or it's a custom part made for a specific manufacturer under custom contract, in which case you'd need to contact the OEM for replacement parts.

First thing I'd do is take some pics, then contact Alpha directly to see if they can help you to identify the part in question.

Thanks.

I already looked at the contact page on their website, and to submit a question you have to enter a lot of information about what company you are with, so that makes me think they are not interested in talking to individuals (i.e., not enough $), but I'll try it.

hint: Make up a company name or use "independent contractor". You can use 'equipment repair' as a services description if it's available.

Check if any of the pins have common connections. What might be happening is that the 8 pin version uses common pins to make a better mechanical conenction to the circuit board.

I didn't do enough testing on the pot. The 4th pin is a 2nd control, it goes from about 5K ohms at either end of the slide to about 500 ohms in the middle, so obviously it is connected to near the middle of the slide. This 2nd control pin is in addition to the 1st control pin, which goes from 0 to 10K ohms from one end of the slide to the other, as I would expect.

So it still looks like I can only use a replacement pot that has 8 pins, the same as what is in the device now.

Thanks
