    I am trying to find and equivalent Photo Sensor to replace Radio Shacks Clear Lens 276-145 sensor because of their cost and backordering. I am not that familiar with electronic terms when it comes down to the component level. The 276-145 works great and want something that does the exact same thing. Is their another sensor out there that can replace it? My light source are bright White LED's. My operating voltage is 5 volts. I am attaching the specs on the 276-146 and also attaching a few parts from Mouser that seem to be familiar, but not sure. Presently the dia I am using is 5mm, but seems most available are 3mm (not a deal breaker).
    Any suggestions would be most welcomed!

    The specs are so general that you will just have to try some other parts and see if they work.

    IR or visible light?

    If you are also running the Emitter, it's good to buy both from the same manufacturer, with the same peak wavelength. Longer distances can be obtained that way.

    For the price Radio Shack sells them for, you could get rather high quality and much more sensitive photo-transistors for under half price ($0.30 to $1.00 in single qty) from digi-key or mouser.
