HLMPD155A

LED Indication - Discrete Overview

The HLMPD155A is a single-color red LED manufactured by Everlight Electronics Co Ltd. It utilizes a T-1 3/4 (5 mm) through-hole package with a tinted dome lens and clear transparency. The component emits light at a peak wavelength of 660 nm with an intensity of 10 mcd. Electrical characteristics include a forward voltage of 1.6 V at a test current of 1 mA, resulting in a power rating of 87 mW. The viewing angle is 24 degrees. Operating temperatures range from -20 C to +100 C.

LED Indication - Discrete Feature Summary

• Through-hole radial mount construction for standard PCB insertion
• Tinted dome lens design providing clear optical transparency
• Low current operation capability optimized for indicator applications

LED Indication - Discrete Applications

• Panel status indicators
• Equipment front panel signaling
• General purpose circuit board indication

LED Indication - Discrete Procurement Notes

Verify component availability as the HLMPD155A is listed as obsolete or discontinued by major distributors. Confirm end-of-life status with the manufacturer before finalizing designs. Check for parameter-equivalent replacements if long-term supply assurance is required. Ensure RoHS compliance documentation matches specific project requirements.

LED Indication - Discrete Selection Notes

Select this component for low-power visual signaling where a 5 mm form factor is necessary. The 1 mA operating current suits battery-sensitive or low-drain circuits. Consider the 24-degree narrow beam width for directional visibility needs. Verify thermal limits against ambient operating conditions given the +100 C maximum rating.

LED Indication - Discrete Part Context

This part belongs to Everlight's standard single-color LED lineup designed for general indication purposes. It represents a traditional through-hole technology component often used in legacy equipment maintenance or cost-sensitive industrial controls. The T-1 3/4 package size offers a balance between visibility and board space efficiency.
