HLMP4719

LED Indication - Discrete Overview

The HLMP-4719 is a single-color, yellow diffused LED manufactured by onsemi. It utilizes a T-1 3/4 (4.825 mm) round lens with radial mounting and a 5.08 mm terminal pitch. The component emits at a peak wavelength of 585 nm with a nominal luminous intensity of 2 mcd. It features a 35-degree viewing angle and a total height of 8.64 mm. This through-hole device is designed for general indicator applications requiring standard axial or radial board integration.

LED Indication - Discrete Feature Summary

• Yellow diffused light emission
• T-1 3/4 radial package design
• Standard 5.08 mm terminal spacing

LED Indication - Discrete Applications

• General purpose electronic indicators
• Panel status signaling
• Consumer appliance front panels

LED Indication - Discrete Procurement Notes

Verify the manufacturer designation carefully, as the HLMP-4719 part number is historically associated with Broadcom Limited (formerly Avago Technologies). While the provided search results list this specific model under onsemi's catalog index, cross-reference the official datasheet to confirm current production status and sourcing channels. Ensure compliance with RoHS material requirements and verify the specific ordering suffix if available in the official documentation.

LED Indication - Discrete Selection Notes

Select this component when a low-cost, standard yellow indicator is required for non-display applications. The T-1 3/4 form factor offers a balance between visibility and compactness. Consider the 2 mcd intensity rating for ambient lighting conditions; higher brightness may be necessary for direct sunlight exposure. Confirm that the 5.08 mm pitch matches the target PCB footprint before finalizing the bill of materials.

LED Indication - Discrete Part Context

This component belongs to the broad category of discrete optoelectronic devices used for visual signaling. Unlike complex integrated circuits, it functions as a simple light source driven by external circuitry. Its classification within power management or sensor catalogs often stems from its role in system status monitoring rather than active signal processing.
