LED Indication - Discrete Procurement Notes

This specific part number is officially listed as a discontinued product by the manufacturer. Procurement efforts should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the component's storage history and shelf life conditions prior to purchase, as long-term storage may affect solderability and optical performance. Ensure that the packaging remains sealed and intact to prevent moisture absorption or physical damage during transit and handling.

LED Indication - Discrete Selection Notes

Engineers selecting this component should note its status as a legacy item within the Everlight portfolio. The reverse package design offers specific mounting advantages for certain PCB layouts, while the rectangular lens provides distinct beam characteristics suitable for uniform illumination tasks. Due to the discontinuation, alternative sourcing strategies must be evaluated against current project requirements. Designers should verify if newer generations of Everlight white LEDs offer comparable luminous intensity and thermal performance for replacement designs.

LED Indication - Discrete Part Context

The 23-21B series represents Everlight's range of surface mount LEDs designed for automated assembly. This specific model belongs to the reverse package category, which differs from standard top-emitting configurations. The W1D suffix indicates white color and specific lens properties, while ANQHY denotes the binning and packaging details. As a consumer-grade component, it targets high-volume manufacturing environments requiring reliable, compact light sources for integrated lighting solutions.

LED Indication - Discrete Replacement Considerations

As a discontinued part, direct substitutes are not explicitly confirmed in public documentation. Engineers should consult Everlight's official obsolescence notices for recommended cross-reference models. Potential replacements must match the reverse package footprint, white color temperature, and rectangular lens dimensions to ensure mechanical and optical compatibility in existing assemblies.
