19-21UYOC/S530-A3/TR8

LED Indication - Discrete Overview

The 19-21UYOC/S530-A3/TR8 is a single-color surface-mount LED manufactured by Everlight. It features a rectangular lens with water-clear transparency and emits Super Yellow/Orange light at a peak wavelength of 605 nm. The component operates with a forward current of 20 mA and a typical forward voltage of 2 V, dissipating up to 60 mW. It provides an optical intensity of 200 mcd with a viewing angle of 130 degrees. The device is housed in a compact 0603 (1608 metric) package, measuring 1.6 mm in length, 1.2 mm in width, and 0.4 mm in height.

LED Indication - Discrete Procurement Notes

Verify the specific suffix A3 against the manufacturer's latest datasheet to confirm lens color and spectral characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for end-of-life notifications as availability may be restricted. Ensure the reel packaging quantity matches production requirements. Validate that the 0603 footprint aligns with the PCB design guidelines.

LED Indication - Discrete Selection Notes

Select this component when a bright yellow-orange indicator is required in a minimal footprint. The 130-degree viewing angle makes it suitable for applications needing wide visibility without precise alignment. Consider the 20 mA forward current requirement for driver circuit design. Compare with other colors in the 19-21 series if different visual signaling is needed. Ensure the operating temperature range meets the environmental conditions of the target application.

LED Indication - Discrete Part Context

This part belongs to Everlight's standard single-color LED portfolio designed for surface-mount technology. The 19-21 series offers various colors and package sizes to support diverse lighting needs. The 0603 size represents a balance between light output and board space efficiency. It is commonly used alongside other components in signal processing and display circuits.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other 0603 yellow LEDs from Everlight such as 19-21/YLC/S530-A3/TR8 or similar variants within the 19-21 family. Verify electrical parameters and mechanical dimensions before swapping. Cross-reference with competitors like Kingbright or Osram for equivalent 0603 yellow SMD LEDs if supply constraints exist.
