Product Overview
5mm Diffused Red Through-Hole LED - Classic Indicator, Soft Uniform Glow, Breadboard Ready
Condition
Unused NOS. Sourced from an electronics distributor consolidating inventory. Leads are straight and untrimmed, domed lenses intact, no visible damage. Tested functional. Photos show the specific units you will receive.
Ships same business day from Idaho. Packed with care to guard the leads in transit.
No hassle resolution if there is an issue. Serving customers since 1999.
Product Overview
Standard 5mm diffused red LED in a through-hole T-1 3/4 package. The diffused lens scatters light evenly, producing a soft uniform glow rather than a focused spot - the classic look for indicator lights and accents. Runs at 20mA with a current-limiting resistor in the circuit.
Key Features
- 5mm (T-1 3/4) through-hole package, 2-pin
- Diffused red lens - soft, wide-angle glow
- Typical forward current: 20mA
- Typical forward voltage: 1.9-2.1V (Not confirmed - verify against your circuit before use)
- Leads straight and untrimmed, ready for breadboard or PCB
- Compatible with Arduino, Raspberry Pi, and standard microcontroller GPIO with appropriate resistor
Applications
- Status and indicator lights on DIY electronics and Arduino projects
- Breadboard prototyping and circuit learning
- Model railroad lighting, diorama accents, and prop building
- Cosplay and wearable electronics accents
- LEGO lighting mods and miniature scene lighting
- Panel indicators in repair and restoration projects
Frequently Asked Questions
Do I need a resistor to use this LED?
Yes. A current-limiting resistor is required. Connecting directly to a voltage source without one will destroy the LED. For a 5V supply at 20mA, a 150-220 ohm resistor is a common starting point - adjust based on your supply voltage and desired brightness.
Will this work with an Arduino or Raspberry Pi?
Yes. Standard 5mm through-hole LEDs are compatible with Arduino and Raspberry Pi GPIO pins. Use a current-limiting resistor on the output pin - typically 220-330 ohms at 3.3V or 5V logic.
What is the exact forward voltage and wavelength?
Typical forward voltage for a 5mm red LED is 1.9-2.1V. Exact wavelength and brightness are not confirmed for this specific lot - verify against your design requirements before use.
How many are available?
Limited quantity remaining from the original distributor lot. Stock will not be replenished once sold through.
The 5mm red through-hole LED has been showing up in breadboards and homebrew circuits since hobbyists first started poking wires into foam. Old stock, straight leads, ready to drop in - whatever you are building, this little light still has work to do.
