5520921805F

LED Indication - Discrete Overview

The Dialight 5520921805F is a bi-level LED circuit board indicator from the 552 series. It features a 5mm T-1 3/4 lens with a round dome shape and diffused surface. The component utilizes through-hole mounting in a right-angle configuration. It emits green light at a wavelength of 563 nm. Electrical characteristics include a forward current of 10 mA and a forward voltage of 2.1 V. The unit provides an optical intensity of 2 mcd with a viewing angle of 65 degrees.

LED Indication - Discrete Feature Summary

• Bi-level dual-emission capability within a single package
• Right-angle through-hole termination for PCB integration
• Diffused round dome lens for wide visibility
• Green spectrum emission optimized for status indication

LED Indication - Discrete Applications

• Electronic equipment status monitoring
• Control panel circuit board indicators
• Industrial machinery operational signaling
• Consumer device power state display

LED Indication - Discrete Procurement Notes

Verify the specific suffix against official Dialight documentation to confirm exact binning and material composition. Ensure compatibility with standard reflow or wave soldering profiles specified in the datasheet. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

LED Indication - Discrete Selection Notes

Select this component when space-constrained designs require dual-color indication on a single footprint. The right-angle form factor facilitates vertical signal routing or specific housing alignments. Consider the 5mm lens size and 65-degree viewing angle for visibility requirements. Evaluate the 10 mA forward current against available drive circuitry capabilities.

LED Indication - Discrete Part Context

This indicator belongs to the Dialight 552 series, which specializes in bi-level LED circuit board indicators. The series offers compact solutions for applications needing multiple status colors in limited board areas. The 5520921805F variant specifically addresses green-light bi-level requirements with right-angle termination.

LED Indication - Discrete Replacement Considerations

Direct substitutes within the 552 series sharing identical bi-level functionality and right-angle through-hole packaging should be evaluated. Verify matching electrical parameters such as forward voltage and current before substitution.
