Procurement Notes

This component is officially classified as End-of-Life (EOL) by Harwin Inc. and is scheduled for discontinuation. Availability is restricted to remaining stock or third-party surplus markets. Verify obsolescence status and lead times carefully before finalizing procurement plans, as direct manufacturing supply is no longer guaranteed.

Selection Notes

Select this part only if the specific 30-position dual-row layout and bottom-entry mechanism align with the mechanical design. Ensure compatibility with the 2.54 mm pitch requirement. Given the EOL status, evaluate alternative M20 series variants with similar electrical characteristics but active production status to ensure long-term supply chain stability.

Part Context

Part of the M20 series rectangular connectors, known for high-density applications. This specific model represents a legacy socket assembly within the broader Harwin portfolio. It complements male header counterparts in the same series to form complete interconnection systems for PCB mounting.
