Overview
The 15-21SUBP/S3179-1/TR8 is a surface-mount white LED from Everlight Electronics. It utilizes a diffused lens within a rectangular package featuring a flat top design, suitable for standard SMD placement processes. The component operates with a typical forward voltage of 2.85V and includes a 140-degree viewing angle to ensure broad light distribution. Designed for reliability, it supports RoHS compliance standards and functions effectively across a range of industrial temperatures.
Feature Summary
- Diffused lens configuration for uniform light emission
- Rectangular package with flat top geometry
- Wide 140-degree viewing angle capability
Applications
- General indicator lighting
- Backlighting applications
- Symbol illumination
Procurement Notes
Verify the specific suffix S3179-1 against the manufacturer's current datasheet to confirm exact binning and optical characteristics. Ensure compatibility with automated pick-and-place equipment due to the SMD form factor. Confirm that the diffused lens specification meets the required luminous intensity targets for the intended enclosure design.
Selection Notes
Select this component when a wide beam angle and soft light diffusion are required for visual indicators. The 140-degree viewing angle makes it suitable for applications where the observer may not be directly in front of the device. Consider the 2.85V forward voltage drop for power budget calculations in low-voltage circuits.
Part Context
This part belongs to Everlight's 15-21 series of surface-mount LEDs. The series is designed for compact electronic assemblies requiring reliable illumination. The specific model integrates a white LED chip with a diffusing compound to reduce glare and improve visibility in various ambient lighting conditions.
Replacement Considerations
Cross-reference with other Everlight 15-21 series variants. Verify package dimensions and pinout compatibility before substituting. Ensure the replacement maintains the required forward voltage and luminous intensity specifications.
