Headers, Receptacles, Female Sockets Procurement Notes

Verify current availability status as this component may be subject to end-of-life notifications or discontinuation. Confirm that the specific pin count and row configuration match the target PCB footprint requirements before ordering. Ensure compatibility with corresponding male header assemblies within the same M52 series family for proper mechanical engagement.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when high-density interconnects are required in space-constrained designs. The 1.27 mm pitch allows for significant pin counts within small footprints. Consider the through-hole termination method for robust mechanical stability compared to surface mount alternatives. Verify that the 4.60 mm stack height fits within the enclosure constraints of the final assembly.
