Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix matches the required contact length and termination style. Confirm that the gold plating thickness meets the application's conductivity requirements. Ensure the surface mount footprint aligns with the PCB design guidelines provided in the official datasheet before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a single-row, low-profile surface mount solution is required. The 0.050-inch pitch suits standard density layouts. Verify that the target pin diameter falls within the specified 0.015 to 0.022-inch range to ensure proper mechanical engagement and electrical performance without excessive insertion force.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Mill-Max 399 series of individual spring-loaded contacts. These components are designed as standalone targets for mating with male pins. They serve as critical interface points in test and measurement hardware where repeated connection cycles and signal integrity are paramount for system functionality.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 0.050-inch pitch and single-row configuration. Verify identical surface mount compatibility and compatible lead diameter acceptance ranges. Cross-reference the official Mill-Max catalog for equivalent series parts with matching mechanical dimensions and material specifications.
