There are a number of factors that go into choosing the right LED indicator for your panel. In order to replace your burnt out LEDs, you must make sure that you have identified the correct pin configuration, mounting case style, size and current. You can also choose from a variety of different color options and manufacturers depending on price point and compatibility.
If you are simply planning to swap and replace an LED indicator, you must pay attention to how the LED is mounted first. LED indicators range in size from 4 mm in diameter to much larger 12 and 18 mm options. They also come in rectangular, round and other shapes. If you want your new indicator to sit in the panel the same way it came out, you will also need to make sure you have the right mounting style. Some LED indicators simply press into place, while others use a nut and washer around the outside to hold them in. The style of case around the LED bulb itself will determine whether or not it fits in the panel correctly.
Voltage and Current
Equally important as the mounting hardware and the size of the indicator is finding the correct voltage and current ratings. There are a wide range of options between 2 mA and 150 mA of current, and you need to choose the one that matches your panel’s output. Voltage ratings also vary drastically from 1.6V to more than 200V.
Once you have made absolutely sure that the hardware part of your LED indicator is correct, you still have plenty of other choices to make. There are a ton of color options, although the most popular are red, white, green and blue. You can also get light diffusing lenses and other accessories that soften the appearance of the LED. Just take the time to match your current LED with the correct mounting style and ratings first.
