HLMPQ155AGR

LED Indication - Discrete Overview

The HLMPQ155AGR is a single-color red LED indicator manufactured by Everlight Electronics Co Ltd. It utilizes a T-3/4 (5 mm) surface-mount package with gull-wing leads and a clear dome lens. The component emits light at a peak wavelength of 660 nm with a viewing angle of 24 degrees. Key electrical parameters include a forward voltage of 1.8 V at a test current of 20 mA, resulting in an optical intensity of 50 mcd. The device operates within a temperature range of -40°C to +100°C and features a moisture sensitivity level of 1.

LED Indication - Discrete Feature Summary

• Surface-mount configuration with gull-wing leads for automated assembly
• Clear dome lens design providing a focused 24-degree viewing angle
• High-temperature operation capability up to 100°C
• Low moisture sensitivity等级 (MSL 1) for standard reflow processing

LED Indication - Discrete Applications

• Panel status indication in electronic equipment
• Power supply status indicators
• Control board visual signaling
• Consumer appliance front panels

LED Indication - Discrete Procurement Notes

Verify the specific suffix AGR against the manufacturer's latest datasheet to confirm lead frame material and plating specifications. Ensure compatibility with standard SMD reflow profiles given the MSL 1 rating. Confirm that the T-3/4 footprint matches the target PCB land pattern dimensions prior to final procurement decisions.

LED Indication - Discrete Selection Notes

Select this component when a low-profile surface-mount red indicator is required for high-temperature environments. The 24-degree beam angle offers more directionality than standard diffused LEDs. Consider the 1.8V forward voltage drop for circuit design calculations. Verify availability as distribution channels may vary due to lifecycle status changes.

LED Indication - Discrete Part Context

This part belongs to Everlight's standard single-color LED family designed for general indication purposes. The T-3/4 form factor provides a compact alternative to through-hole T-1 packages while maintaining robust mechanical stability. It serves as a direct surface-mount solution for legacy designs requiring 5mm equivalent height constraints.

LED Indication - Discrete Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other T-3/4 SMD red LEDs from different manufacturers only after verifying pinout compatibility and luminous intensity tolerances.
