Procurement Notes
Verify obsolescence status before procurement as the manufacturer has scheduled this part for discontinuation. Confirm specific contact plating requirements against available end-of-life inventory. Request official End of Life (EOL) notification documentation from authorized distributors to manage supply chain risks effectively.
Selection Notes
Select this component for applications requiring dual-row surface mount receptacles with secure latching mechanisms. Ensure PCB layout accommodates the specific stacking height and footprint dimensions. Verify that the copper alloy contacts meet the required current carrying capacity and environmental resistance standards for the target operating conditions.
Part Context
This component belongs to the Harwin M20 series, which offers various row configurations and termination styles. The M20 series is designed for high-reliability applications in demanding environments. This specific model represents a dual-row variant optimized for space-constrained board-to-board connections.
Replacement Considerations
No public confirmed substitute part numbers are available. Due to the scheduled obsolescence, engineers must evaluate alternative connectors from the same or different series immediately to prevent production delays.
