LTL-4233-R2

LED Indication - Discrete Overview

The LTL-4233-R2 is a green diffused LED from Lite-On Inc., manufactured in the T-1 3/4 (5mm) radial package. It operates with a typical forward voltage of 2.1V at a test current of 10mA, emitting light at a peak wavelength of 565nm and a dominant wavelength of 569nm. The component provides a luminous intensity of 19mcd with a viewing angle of 36 degrees. It features a circular lens with a dome style and has a maximum height of 8.60mm. The part is RoHS compliant and classified under EAR99.

LED Indication - Discrete Feature Summary

• Diffused green lens for wide-angle light distribution
• Radial through-hole mounting configuration
• Standard circular dome lens geometry

LED Indication - Discrete Applications

• General purpose panel indicator lighting
• Power status indication on electronic equipment
• Control board operational signaling

LED Indication - Discrete Procurement Notes

Verify that the suffix -R2 corresponds to the specific reel packaging requirement if automated placement is intended, as standard datasheets may list bulk quantities. Confirm the exact pin spacing matches the target PCB footprint, noting the radial lead configuration. Ensure the supplier documentation explicitly lists the -R2 variant to avoid receiving non-reeled equivalents. Cross-reference the manufacturer's latest revision history for any changes in mechanical dimensions or electrical tolerances prior to finalizing the bill of materials.

LED Indication - Discrete Selection Notes

Select this component when a 36-degree viewing angle and diffused emission are required for visibility. The 2.1V forward voltage suits low-voltage logic circuits without excessive series resistance. Compare against the transparent LTL-4232N if higher intensity or narrower beam is needed. Consider the T-1 3/4 size constraints for tight panel cutouts. Verify thermal dissipation requirements against the 60mW maximum power rating for continuous operation environments.

LED Indication - Discrete Part Context

This part belongs to the Lite-On LTL series of discrete through-hole LEDs. It shares the T-1 3/4 form factor with other variants like the LTL-4221 and LTL-4232N. The -R2 suffix typically denotes tape and reel packaging for manufacturing efficiency, distinguishing it from bulk-packed versions. It serves as a direct functional replacement for older green T-1 3/4 LEDs in existing designs requiring similar optical characteristics.

LED Indication - Discrete FAQ

What is the difference between LTL-4233 and LTL-4233-R2?

The LTL-4233-R2 specifies the reel packaging format, whereas the base LTL-4233 often refers to bulk packaging. The electrical and optical parameters remain identical.

Is the lens color different from the emitted light color?

No, both the lens color and the emitted light are green. The lens is diffused to scatter the light rather than transmit it directly.
