I did so for my fta satellite receiver, and it made all the difference in the world. It's a diode, and has polarity, so pay attention!
I picked up the RS 276-0143 "High Output Infrared LED" from your link, and also picked up the 276-0142 "Infrared Emitter and Detector" as well. To my surprise, the 276-0143 emitter was quite a bit dimmer than any of my remotes when viewed on my phone camera. (my multimeter has a function to test and power LEDs and diodes.
I thought, perhaps my multimeter is not powering the LED emitter with the same power as the remote? So I tested the 276-0142 emitter, and it was very bright, much brighter than the 0143, about the same as some of the remotes I tested.
Upon looking at the specs on the package, the 0143 has 16mW radiant power, the 0142 has 75.5mW. I then attached the detector photo diode from the 276-0142 to a voltmeter, set it on a/c, and measured 380mV from the 0143, and 420mV from the 0142 emitter, when touching the detector. Not nearly the difference I expected.
Testing from about 24" showed the 0143 @ 9.4mV, and the 0142 @ 66mV. That's more like it. A Panasonic Showstopper remote @ 105mV, the Homeworx remote @ 46mV, and a Harmony 300 remote @ 54mV and the widest pattern. Darkened room. I suppose the battery voltage in the respective remotes could play a part in these readings, although the Harmony batteries are new Duracells.
My hypothesis is that, while the Homeworx remote is somewhat weak, I believe the problem is in the detection circuitry. Perhaps the detector diode is being shielded or is not aligned properly?
I think you are on to something, and I may switch out the emitter in my Homeworx remote, as well as the detector in the HW-150. (Won't be messing with the Harmony, too expensive to replace, as the 300 is no longer made.) I'll try the detector 1st, and report back. I think I will use the more powerful 0142 emitter for my test. It may take me a week due to the holidays.
Thanks for the good idea!
