AA3021LSESK/J4-TR

LED Indication - Discrete Overview

The AA3021LSESK/J4-TR is a single-color surface-mount LED manufactured by Kingbright, designed for indicator applications. It emits orange light with a peak wavelength of 605 nm and features a clear lens. The component utilizes a 2-SMD J-leaded package with dimensions of 2.70 mm in length, 2.00 mm in width, and a maximum height of 1.50 mm. Key electrical parameters include a typical forward voltage of 2.1 V at a test current of 2 mA. The device offers a viewing angle of 125 degrees and has a luminous intensity of 400 mcd. It operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

LED Indication - Discrete Feature Summary

• Compact SMD form factor with J-leaded configuration for efficient PCB space utilization
• High-intensity orange emission optimized for visual status indication
• Wide viewing angle ensuring visibility from multiple perspectives

LED Indication - Discrete Applications

• Electronic equipment status indicators

LED Indication - Discrete Procurement Notes

Verify the specific suffix J4-TR against the manufacturer datasheet to confirm the orange color variant and packaging type. Ensure compatibility with standard reflow soldering profiles for 2-SMD components. Confirm moisture sensitivity level (MSL) handling requirements prior to assembly to maintain component integrity during manufacturing processes.

LED Indication - Discrete Selection Notes

Select this component when a low-profile orange indicator is required for surface-mount assembly. Consider the 125-degree viewing angle and 400 mcd intensity for visibility needs. Evaluate the 2.70mm x 2.00mm footprint against available board space constraints compared to other AA3021 series variants.

LED Indication - Discrete Part Context

This part belongs to the Kingbright AA3021 series of single-color LEDs. The series includes various color options such as red and yellow, sharing similar physical dimensions and mounting characteristics. The AA3021 series is widely used in general-purpose electronics for visual signaling due to its reliability and compact size.

LED Indication - Discrete Replacement Considerations

Direct substitutes within the same series include AA3021LSYSK/J3-TR (Yellow) and AA3021LSESK/J3-TR (Red). These parts share identical mechanical footprints and electrical testing conditions, allowing for potential pin-compatible swaps if color differentiation is not critical.
