5219603F

LED Indication - Discrete Overview

The Dialight 5219603F is a single-color LED indicator designed for through-hole mounting. It emits red light with a peak wavelength of 630 nm and features a diffused lens transparency. The component utilizes a T-1 (3 mm) dome-shaped package with a tinted lens. Electrical characteristics include a forward voltage of 2 V at a test current of 10 mA, with a power rating of 100 mW. The device offers a viewing angle of 45 degrees and operates within a temperature range of -55 C to +100 C.

LED Indication - Discrete Feature Summary

• Provides high-visibility red illumination via a diffused lens for clear status indication.
• Features a robust 3 mm through-hole construction suitable for standard panel applications.
• Operates reliably across an extended industrial temperature range.

LED Indication - Discrete Applications

• Panel-mounted equipment status indicators
• Industrial control system signaling
• Electronic device front-panel displays

LED Indication - Discrete Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement. Confirm that the ordering suffix matches the required lens transparency and color specifications. Ensure compatibility with existing PCB layouts and thermal management requirements for the target application environment.

LED Indication - Discrete Selection Notes

Select this component when a standard 3 mm through-hole red LED is required for visual signaling. Consider the 45-degree viewing angle and diffused lens properties for optimal visibility in direct-line-of-sight applications. Evaluate the 2 V forward voltage drop against available drive circuitry to ensure proper current limiting and power dissipation within the 100 mW rating.

LED Indication - Discrete Part Context

This part belongs to the Dialight 521 series of discrete LEDs, which are widely used in industrial and commercial electronics. The series provides various colors and lens configurations optimized for reliability and visibility. As a single-color device, it serves as a fundamental component for basic status indication tasks where multi-color functionality is not required.

LED Indication - Discrete Replacement Considerations

Cross-reference with other 3 mm through-hole red LEDs from manufacturers such as Kingbright or Osram if supply constraints exist. Verify mechanical dimensions, pin spacing, and electrical parameters to ensure functional equivalence without redesigning the host circuit board.
