Cds replacement

I have been looking for a SMD Cds photo cell, or a direct replacement SMD device. Any suggestions?

Cadmium is one of the evil chemicals they are trying to ban. Problem is that there is nothing quite like it.

As to surface mount, the Cds cell is dependent on area for it’s effect so I doubt if a surface mount device would be usable.

This is for a Evaluation board, so the area isn’t really an issue. I didn’t want any components that could get knocked around when storing/handling the eval board.

I guess I can place the Cds cell as close to the board as possible but my space is limited to about 4mmx4mm.

This seems to be a close, http://www.panasonic-electric-works.nl/pewswe/nl/downloads/ds_61803_0001_en_napica.pdf But still not a direct replacment.

So I guess I will start looking for a small Cds cell. Mouser doesn’t seem to carry them, but I found them at digi-key.

Thanks for the reply.

I think you missed the point, area is an issue because a small area Cds cell will not work, so they don’t make them.

Nothing else works like it, that is a light dependent resistance, so you won’t find a replacement.

Here are some that should fit,
4.2mm http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=PDV-P9007-ND
4x3.5mm e-clec-tech.com

But for future uses, I will need to work out an alternative.
