Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix against the official Harwin datasheet to confirm orientation and packaging details. Ensure compatibility with standard reflow soldering profiles for lead-free processes. Confirm that the selected variant matches the required row count and position quantity for the target application layout.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, high-pin-count solution is required for space-constrained designs. The 1.27 mm pitch allows for dense routing while maintaining electrical isolation. Consider the 3.60 mm height limit during mechanical stack-up analysis to ensure clearance with adjacent components or enclosures.
