1.8YDL

Overview

The Bivar Inc. 1.8YDL is a discontinued single-color through-hole LED component featuring a 1.8 mm yellow dome lens with diffused transparency. It operates at a forward current of 2 mA and a forward voltage of 2 V, emitting light at a wavelength of 590 nm with an intensity of 1 mcd. The device has a power rating of 10 mW and is supplied in bulk packaging.

Feature Summary

• Through-hole mounting configuration for standard PCB insertion
• Yellow diffused dome lens design for broad visibility
• Single-color emission optimized for indicator applications

Applications

• Electronic equipment status indication
• Panel-mounted visual signaling
• General-purpose circuit board indicators

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before integration into new products. Confirm availability of existing stock or last-time buy options from authorized distributors. Ensure alternative components are identified to mitigate supply chain risks associated with discontinued electronic components.

Selection Notes

Consider the 1.8 mm form factor and yellow color output when matching aesthetic requirements. Evaluate the 2 mA forward current and 2 V forward voltage against available drive circuits. Assess the diffused lens characteristics for required viewing angles and brightness levels in the target application environment.

Part Context

This component belongs to the 1.8mm discrete LED series manufactured by Bivar Inc. It represents a legacy through-hole LED solution designed for simple visual feedback in electronic assemblies. As a discontinued item, it serves as a reference for maintaining older hardware designs rather than initiating new development projects.

Replacement Considerations

Consult official Bivar documentation for verified substitute part numbers. Do not assume functional equivalence with generic LEDs without verifying electrical parameters and mechanical dimensions.
