Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix 'R' to confirm the right-angle orientation and surface mount compatibility. Ensure the ordering part number matches the required contact count and row configuration. Cross-reference the datasheet for precise footprint dimensions and recommended solder paste stencil design to guarantee reliable reflow soldering results during production.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when space constraints require a low-profile right-angle connection between PCBs. The 2.00mm pitch offers a balance between pin density and manufacturing tolerance. Consider the thermal resistance of the LCP material if operating near peak reflow temperatures or in high ambient heat environments compared to standard nylon variants.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the M22 series, which provides industrial-standard connectors with fine 2mm spacing. The series supports both through-hole and surface mount technologies, offering flexibility in PCB layout. The M22 line is engineered to meet stringent mechanical and electrical requirements for modern electronics manufacturing.
