91-21SURC/S530-A3/TR9

LED Indication - Discrete Overview

The 91-21SURC/S530-A3/TR9 is a single-color surface-mount LED manufactured by Everlight Electronics Co Ltd. It emits high-brightness red light with a peak wavelength of 632 nm and a dominant wavelength of 624 nm. The component features a Z-shaped bend package configuration, measuring 2.50 mm in length, 2.00 mm in width, and a maximum height of 2.90 mm. It operates at a forward current of 20 mA with a typical forward voltage of 2 V. The lens is colorless and water-clear with a dome shape and a diameter of 1.90 mm. The device has a viewing angle of 25 degrees and a luminous intensity of 600 mcd.

LED Indication - Discrete Feature Summary

• Z-shaped bend lead frame design for secure surface mounting

• Standard SMD form factor compatible with automated assembly

LED Indication - Discrete Applications

• Panel status indicators
• Appliance control interfaces
• Instrumentation displays

LED Indication - Discrete Procurement Notes

Verify the specific suffix TR9 against official Everlight documentation to confirm reel quantity and tape specifications. Ensure compatibility with standard reflow soldering profiles and moisture sensitivity level requirements during storage and handling procedures.

LED Indication - Discrete Selection Notes

Select this component when a low-profile red indicator with a Z-bend footprint is required. Compare electrical parameters such as forward voltage and luminous intensity against circuit constraints. Verify mechanical dimensions against PCB silkscreen and pad layout requirements before finalizing the design.

LED Indication - Discrete Part Context

This part belongs to the 91-21S series of single-color LEDs from Everlight. The series offers various color options and packaging styles including gull-wing and Z-bend configurations. The S530-A3 designation typically refers to the specific resin and lens characteristics for red emission variants within this product line.

LED Indication - Discrete Replacement Considerations

Cross-reference with other Everlight red LEDs in the 91-21S family sharing the same Z-bend package and electrical ratings. Verify pinout orientation and mechanical tolerance compatibility before substituting.
