Overview
The 57-21UYC/S530-A6/TR8 is a single-color surface-mount LED manufactured by Everlight Electronics. It emits brilliant yellow light with a peak wavelength of 591 nm and utilizes a water-clear lens. The component features a round shape and measures 1.6 mm in size. It operates within a temperature range of -40 °C to 85 °C and has a maximum forward current rating of 0.025 A. The device is RoHS compliant and supplied in tape and reel packaging.
Feature Summary
- Emits brilliant yellow light with a 130-degree viewing angle
- Utilizes a water-clear lens for optical transmission
- Designed for surface mount technology (SMD) installation
Applications
- Indicator lights in electronic devices
- Status indication in consumer electronics
- Instrument panel illumination
Procurement Notes
Verify the specific suffix A6 against official Everlight documentation to confirm exact binning or optical characteristics, as suffixes often denote specific performance tolerances. Ensure the TR8 packaging designation matches the required reel specifications for automated assembly processes. Cross-reference the part number with current manufacturer datasheets to confirm availability status and compliance certifications prior to procurement.
Selection Notes
Select this component when a compact 1.6 mm SMD yellow LED is required for space-constrained designs. The 130-degree viewing angle provides wide visibility for indicator applications. Verify that the 0.025 A maximum forward current aligns with the target circuit's drive capabilities. Confirm that the operating temperature range meets the environmental requirements of the final application.
Part Context
This part belongs to Everlight's single-color LED portfolio, specifically the 21 series which typically denotes small form factor surface-mount devices. The S530 code likely refers to the specific lens material or color binning standard used by the manufacturer. The TR8 suffix indicates the standard 7-inch tape and reel packaging format commonly used in high-volume manufacturing environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult Everlight's official substitution guide or contact the manufacturer directly for verified alternatives.
