Headers, Receptacles, Female Sockets Procurement Notes

Verify RoHS compliance status directly with the manufacturer, as documentation indicates non-compliance for specific variants. Confirm current production lifecycle status and lead times prior to integration. Ensure mating components match the 2.54 mm pitch and dual-row geometry. Validate thermal and mechanical ratings against application requirements before finalizing procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 56-position dual-row header is required for vertical board stacking. The 2.54 mm spacing offers standard footprint compatibility. Consider the through-hole mounting method for robust mechanical stability. Evaluate space constraints to accommodate the dual-row profile and ensure adequate clearance for mating connectors during assembly.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Mill-Max 0399 series of interconnect headers. The series specializes in precision-machined rectangular connectors designed for demanding industrial and commercial applications. Mill-Max manufactures these components in the United States, emphasizing reliability and service convenience for global supply chains requiring high-performance interconnect solutions.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must maintain the 56-position count, dual-row layout, and 2.54 mm pitch. Verify that alternative headers support identical through-hole termination and physical dimensions. Ensure mating pin receptacles align with the specified contact length and insulation height to prevent mechanical interference or electrical misalignment.
