Procurement Notes
This component is designated as End-of-Life (EOL) by the manufacturer. A discontinuation notification indicates that production will cease, with availability restricted until July 7, 2026. Verification of current stock status and final procurement timelines requires direct consultation with authorized distributors or the manufacturer, as standard supply channels may no longer support new orders.
Selection Notes
Engineers should evaluate this part only if legacy design continuity is required. Due to the EOL status, alternative components with similar PCM interfaces and 8-bit resolution should be considered for new designs. Verify that the SOP-20 package footprint and 5V operating voltage align with existing system constraints before proceeding with any remaining inventory usage.
Part Context
The W681511 series belongs to Nuvoton's line of single-channel voiceband CODECs. This specific variant differs from others in the family primarily through its packaging configuration and suffix designation. It shares core functional specifications with related models like the W681512WG, though package types and availability statuses vary across the product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Given the End-of-Life status, engineers must identify compatible alternatives independently based on interface requirements and pinout compatibility.
