    It is discontinued I got them from surplus places They are not very specific and if one modifies the gain of the circuit we had good luck years ago with ones that are surplus

      I never had one fail, and out of close to 250 units in the field. I had plenty of LED's to replace because as they fade they go out of range, even for the gain adjust. I'd recommend that you contact DTS as they are still in Business.

        I had to replace lots of them over the years they lost their sensitivity with age

          I will try with another one.almost as similar.

          I have also many years ago had a few which like this one,dropped dead.At that time we had them repaird at DTS.

            Alan, try this one:

            https://www.digikey.com/en/products/...3910PM/8544293

            It should work, it might be a higher profile so you may have to adjust the reader's focus to get it to read properly. They are about $6 each so worth a try.

            I found it through this company (which was first in Google Search).

            https://marktechopto.com/marktech-de...oto-detectors/

            As a note, for all who read this: When doing a search for specific part, if it comes up blank try a search for a GENERIC type of the same part. My search for just the S04552 also came up blank, BUT adding in "Photodiode" got the results.

            It will save you aggravation and has, so far, rarely failed me. I have been able to find replacements for almost everything with this method.
