3SYT-S

LED Indication - Discrete Overview

The Bivar Inc. 3SYT-S is a discontinued through-hole LED indicator featuring a 3mm T-1 radial package with a super yellow lens. It emits light at a peak wavelength of 590nm (super yellow) or 585nm depending on source documentation, with a typical forward voltage of 2V. The component offers a luminous intensity of 50mcd and a narrow viewing angle of 30 degrees. It is housed in a tinted yellow lens with a domed top style. This discrete optoelectronic device was designed for panel mount indication applications requiring high visibility in the yellow spectrum.

LED Indication - Discrete Feature Summary

• Super yellow emission color for high visibility indication
• Radial through-hole mounting configuration
• Narrow 30-degree viewing angle for directional focus

LED Indication - Discrete Applications

• Panel mount status indicators
• Equipment power state signaling
• Discrete optical indication modules

LED Indication - Discrete Procurement Notes

Verify component obsolescence status prior to procurement as the 3SYT-S is no longer manufactured by Bivar Inc. Sourcing should focus on authorized distributors holding remaining stock or approved substitute components. Confirm RoHS compliance and lead-free status against specific supplier certifications. Validate that alternative parts match the required electrical and mechanical specifications for the intended application.

LED Indication - Discrete Selection Notes

Select this component only if legacy compatibility with existing PCB layouts is required. Consider the narrow 30-degree viewing angle when designing optical paths. Evaluate thermal management requirements for through-hole soldering processes. Ensure the 2V forward voltage aligns with the driving circuit design constraints for reliable operation in industrial or commercial equipment environments.

LED Indication - Discrete Part Context

Bivar Inc. specializes in light pipes and LED indication solutions using specialized engineering approaches. The 3SYT-S belongs to their discrete LED product line, focusing on visual signaling rather than illumination. This part represents a standard industry form factor used for clear visual feedback in electronic assemblies where specific color coding and directional lighting are critical for user interface clarity.

LED Indication - Discrete Replacement Considerations

The 3SYT-S is obsolete. Available substitutes include similar through-hole yellow LEDs such as the Everlight Electronics Co Ltd. 264-7UYD/S530-A3. Verify that replacement parts match the 3mm T-1 package dimensions and 30-degree viewing angle requirements to ensure physical fitment and optical performance consistency in the original design.
