Hi everyone! Here is my first post here.
I need help to identify  LED in the attached photo (or whatever it is) and to source the replacement.

this is from roller mouse

happy new year!
Brumby:
What makes you think you need to replace it?
ataradov:
And if you really need to replace it (highly unlikely), you would have to look at the sensor model. You are not likely to find the complete datasheet, but you may at least find the wavelength. You need to find an LED with the same or similar wavelength.

Although those sensors have pretty wide sensitivity range, so any random red led may work.
Brumby:
What if it's an IR LED?

It is possible, of course. But that looks like a standard Avago sensor that uses visible light.
