Procurement Notes
Verify the specific suffix 'R' against official Harwin documentation to confirm reel packaging or variant status. Confirm RoHS compliance and REACH SVHC declarations as required by project specifications. Cross-reference the full part number to ensure correct contact plating and insulation material selection before procurement.
Selection Notes
Select this component for applications requiring robust, latched connections in space-constrained environments. Ensure the mating socket matches the 2mm pitch and dual-row layout. Verify that the operating voltage and current ratings align with the circuit requirements and environmental conditions.
Part Context
This part belongs to the Datamate L-Tek family, designed for high-density interconnects. It complements female receptacles and cable assemblies within the same ecosystem. The series is known for durability in harsh industrial and medical settings, offering versatile mounting options and secure mechanical retention.
Replacement Considerations
Compatible substitutes include other Harwin Datamate L-Tek headers with matching 20-position, dual-row, male configurations. Verify identical pitch, termination type, and latching features when evaluating alternative part numbers from the same manufacturer.
