Procurement Notes

Verify current availability status as this part number may be subject to discontinuation or limited supply constraints. Confirm specific manufacturing lot dates and RoHS compliance documentation prior to procurement. Ensure storage conditions meet manufacturer recommendations to preserve solderability of the tin-plated contacts during extended inventory holding periods.

Selection Notes

Select this component when a dual-row surface mount socket with thirty positions is required. Verify that the mating header matches the 2.54 mm pitch and bottom entry design. Consider thermal profiles during reflow soldering to ensure compatibility with the nylon housing material. Confirm mechanical stacking height requirements align with the connector specifications.

Part Context

This component is part of the Harwin M20 series, a widely used line of rectangular connectors. The series offers various configurations including single and dual rows with different termination styles. The M20-7853046 specifically addresses needs for dense, low-profile connections in space-constrained applications requiring robust surface mount capabilities.

Replacement Considerations

No public confirmed substitute part numbers are available for this discontinued item. Evaluate compatible alternatives within the same M20 series family that match the thirty-position count and dual-row layout. Cross-reference pin assignments and mechanical dimensions before adopting any replacement solution.
