Overview
The Würth Elektronik 151031YS05900 is a single-color yellow LED indicator designed for through-hole mounting. It features a radial lead configuration within a T-1 (3mm) package. The component utilizes a mono-diffused lens to provide uniform light emission. Key electrical parameters include a forward voltage of 2.1V and a maximum continuous forward current of 30mA. The peak emission wavelength is specified at 585nm, classifying it as a yellow light source suitable for general electronic equipment status indication.
Feature Summary
- Through-hole radial lead construction for standard PCB insertion
- Mono-diffused lens design for consistent visual indication
- T-1 (3mm) cylindrical package format
Applications
- Status indication in general electronic equipment
- Panel mount indicators requiring 3mm LED form factor
- Control board signaling applications
Procurement Notes
Verify the specific ordering suffix against the official datasheet to ensure correct wavelength and binning specifications. Confirm that the application environment remains within the recommended operating temperature range defined by the manufacturer. Ensure PCB footprint dimensions match the T-1 radial lead spacing to guarantee proper mechanical fit during assembly.
Selection Notes
Select this component when a 3mm through-hole yellow LED with diffused output is required. Compare the 2.1V forward voltage drop against available drive circuitry to ensure adequate headroom. Consider the 30mA current rating when designing series resistors or constant current sources to prevent thermal overstress during operation.
Part Context
This part belongs to the Würth Elektronik WL-TMRC series of through-hole monochromatic LEDs. The series offers various colors and lens types optimized for visibility. The 151031YS05900 specifically addresses needs for yellow indication in compact 3mm packages, providing a standardized solution for discrete LED applications across industrial and consumer electronics sectors.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the available documentation. Verify compatibility with existing footprints if considering alternative manufacturers. Ensure any replacement matches the T-1 physical dimensions and 2.1V forward voltage characteristics to maintain circuit integrity.
