The 15-21SYGC/S530-E2/3T is a single-color surface-mount LED manufactured by Everlight Electronics Co Ltd. It emits yellow-green light with a peak wavelength of 573 nm and a luminous intensity of 21 mcd at a forward current of 20 mA. The component utilizes a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 0.8 mm in height. It features a water-clear lens and operates within a temperature range of -40°C to +85°C.
Verify the specific suffix /3T against official Everlight documentation to confirm packaging quantity and reel specifications. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance status as defined in the latest datasheet revision. Confirm availability through authorized distributors given potential lifecycle changes.
Select this component when a yellow-green indicator is required in a 1206 form factor. Consider the 573 nm peak wavelength for visibility requirements. Evaluate the 21 mcd intensity against ambient lighting conditions. Compare thermal resistance and forward voltage characteristics with alternative LEDs if space constraints or power budgets are critical design factors.
This part belongs to Everlight's standard single-color LED portfolio designed for general-purpose indication. The 15-series typically denotes specific package dimensions and lead configurations. The S530 code refers to the specific lens material and color treatment used to achieve the yellow-green emission profile within the 1206 package style.
Publicly confirmed substitute part numbers were not identified in the provided source data. Cross-reference with other 1206 yellow-green LEDs from Everlight or other manufacturers only after verifying electrical parameters and mechanical dimensions.
