Microchip MCP41010 digital potentiometer availability/equivalent

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.

You can either create a small board that will have the DIP size on top of which you solder a SMD chip. It shouldn't be too hard to do.

Or you could ask for a sample here:

You may not receive it, but it's worth trying. Cheers Olivier

Could call Farnell and ask for a quote for the desired package - they do offer that service. Or buy on-line direct from Microchip - worked for some PICs I needed. hth Neil

I was looking at the Maxim/DalSemi DS1804 trim pot. data sheet just this morning. I remember that it's available in 8-pin .300" DIP and 10K. Dunno if it's pin compatable w/ Microchip part.

why not use buy.microchip.com ?

A useful suggestion. I didn't realise that Microchip offered this facility. 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!

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.

Well another suggestion is to see if Microchip will sample it for you.

Use the sample link right next to the buy link.

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.
