I am trying to find a UK distributor for the Microchip MCP41010 digital potentiometer. This is an 8-pin dil chip containing a 256-step 10k pot controlled by an SPI interface. So far I have only found the device in Farnell's catalog but, unfortunately, only in surface mount format (I want 8-pin dil). Can anyone suggest a UK supplier or, alternatively, an equivalent device from another manufacturer? All the other similar devices that I have found use a simpler 2-wire up/down interface. This is unsuitable as it is a replacement part rather than for a new design.

It shouldn't be too hard to do. Or you could ask for a sample here: http://microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1953&device=en010494 You may not receive it, but it's worth trying. Cheers Olivier

I remember that it's available in 8-pin .300" DIP and 10K. Dunno if it's pin compatable w/ Microchip part.

On this occasion, however, the components would cost 96p with �12 shipping (from Thailand) and �5 handling charge! Maybe in the future when I require other parts at the same time!

Dunno if it's pin compatable w/ Microchip part.Unfortunately this is one of the devices with the 2-wire up/down interface that I referred to above. It also has only 100 step positions rather than 256.

Now since it's on their dime (or pence) it may be a bit slow in getting to you. But they will ship you the exact part for no cost whatsoever. They seem to be having some ASP.Net issues right at the moment. So take a stap at it a bit later. BAJ
