Headers, Receptacles, Female Sockets Procurement Notes

Verify specific manufacturing lot dates and RoHS compliance status directly with the supplier prior to ordering. Confirm that the press-fit tail length and guide pin specifications match your PCB design requirements. Ensure that the thermal profile during assembly does not exceed the maximum rated operating temperature of the polymer housing material.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-density, low-profile connection is required between parallel boards. The press-fit interface eliminates the need for reflow soldering, reducing thermal stress on components. Verify that the 3 A current rating per contact aligns with the system's power distribution needs and that the 750 V insulation rating meets safety standards.
