1.8YD

Overview

The Bivar Inc. 1.8YD is a single-color through-hole LED from the 1.8mm Discrete LED series, emitting yellow light with a peak wavelength of 590 nm. It features a 1.8 mm dome lens with diffused transparency and operates at a forward current of 2 mA and forward voltage of 2 V. The component has a power rating of 10 mW and an optical intensity of 1 mcd. Designed for bulk packaging, it functions within a temperature range of -25°C to +85°C.

Feature Summary

• Emits yellow light via a 1.8 mm diameter dome-shaped lens
• Utilizes through-hole mounting technology for PCB integration
• Features diffused lens transparency for wide viewing angles

Applications

• Panel status indicators
• Equipment power signaling
• Control board visual feedback

Procurement Notes

Verify the End-of-Life (NRND) status before procurement, as this designation indicates the component is not recommended for new designs. Confirm RoHS compliance details directly with the manufacturer or authorized distributors. Ensure that existing inventory sources are reliable due to potential supply chain limitations associated with discontinued product lines.

Selection Notes

Select this component when a low-current yellow indicator is required for legacy or specific design constraints. Compare against the 1.8PGC or 1.8RD models if different color outputs are needed while maintaining identical physical dimensions and mounting styles. Verify that the 2 mA operating current aligns with the target circuit's power budget and drive capabilities.

Part Context

This part belongs to the 1.8mm Discrete LED family manufactured by Bivar Inc. It shares mechanical specifications with other colors in the series, such as the 1.8PGC and 1.8RD, differing primarily in semiconductor material to achieve the specific yellow emission spectrum. The series is characterized by compact dome lenses suitable for high-density panel applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Bivar channels for approved cross-references or consider redesigning for currently active components in the same form factor.
