Overview
The Würth Elektronik 151033RS03000 is a red light-emitting diode from the WL-TMRW series, designed for through-hole mounting. It features a 3mm round lens with a clear colorless epoxy and a dome style. The component emits light at a peak wavelength of 625nm and a dominant wavelength of 630nm. Typical forward voltage is 2.1V at a test current of 20mA. It offers a viewing angle of 30 degrees and a luminous intensity of 800mcd. The maximum height is 5.55mm.
Feature Summary
- Radial through-hole package suitable for standard PCB assembly
- Clear colorless dome-style lens for focused beam projection
- High luminous intensity output for visible status indication
Applications
- Panel indicator lights for electronic equipment
- Power supply status signaling
- Control board visual feedback systems
Procurement Notes
Verify the specific ordering suffix to confirm the exact optical characteristics, as variations exist within the WL-TMRW series. Ensure the radial lead configuration matches the target PCB footprint dimensions. Confirm RoHS compliance status via the manufacturer's latest documentation before finalizing procurement specifications.
Selection Notes
Select this component when a high-intensity red indicator is required in a 3mm radial form factor. The 30-degree viewing angle provides directional visibility compared to wider-angle alternatives. Consider the 2.1V forward voltage drop for circuit design compatibility. This part serves as a direct replacement for generic 3mm red LEDs where higher brightness is necessary.
Part Context
This LED belongs to the WL-TMRW series, which focuses on high-brightness performance in standard through-hole packages. Würth Elektronik utilizes specific phosphor formulations to achieve consistent color purity and intensity. The series supports various colors, with this model dedicated to red spectrum applications requiring reliable long-term operation.
Replacement Considerations
Generic 3mm red through-hole LEDs may serve as substitutes if luminous intensity requirements are relaxed. Verify that the substitute part maintains similar forward voltage characteristics to ensure existing driver circuits remain compatible without modification.
