Procurement Notes

This component is officially discontinued by the manufacturer and distributor. Availability is limited to existing stock or secondary market sources. Verify part authenticity and condition carefully when sourcing from third-party suppliers. No new production units are available through official channels.

Selection Notes

Consider this part only for legacy system maintenance or replacement where exact pin compatibility is required. Evaluate alternative modern metering SoCs from the same manufacturer family for new designs due to discontinuation status. Ensure interface and memory requirements match the original design specifications.

Part Context

Part of the 78M6612 series of single-converter technology metering ICs. Designed specifically for single-phase power applications. Shares architectural similarities with other variants like 78M6612-GT/F/P2 but differs in package type and manufacturing lot specifications.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific discontinued variant. Engineers should consult Analog Devices documentation for recommended obsolescence alternatives within the 78M66xx series.
