Key Features & Advantage:

Elevated 4.3mm Base Design: The specialized 4.30mm tall plastic housing functions as an integrated standoff, delivering crucial physical clearance between parallel PCBs to safeguard taller surface-mount components from short circuits.
Dual-Row High Density: Combines the dual-row matrix design with standard 2.54mm spacing, optimizing multi-signal routing while maintaining high mechanical rigidity.
Rugged Through-Hole Mounting: The DIP pins anchor securely into the PCB holes, providing premium solder joint strength capable of withstanding industrial-grade vibrations and repetitive plug-in stress.
Excellent Heat Resistance & Customization: Molded with LCP or NL6T engineering plastics (UL 94V-0) for compatibility with reflow and wave soldering; customizable with Gold Flash, Gold 3U", or selective Plating Tin.
Mating Compatibility: Pairs perfectly with ELETE's comprehensive double-row socket range, including HFNDSH8YP, HFNDS68, HFNDM8Y, HFNDM11, HFNDM71, and more.
