Single Row vs Dual Row Pin Header

Choose a single-row pin header when the PCB needs a simple low-pin-count connection or narrow board edge layout. Choose a dual-row pin header when the design needs higher signal density, stronger mating alignment or a compact two-row connector footprint.

Comparison table

Item	Single-row pin header	Dual-row pin header
Typical format	1xN positions	2xN positions
Board space	Longer and narrower footprint	Shorter connector length with two-row width
Signal density	Lower density, easier visual inspection	Higher density for compact PCB layouts
Mating review	Confirm mating socket or jumper direction	Confirm row spacing, polarity, pin numbering and mating socket
RFQ details	Pitch, positions, height, tail length and plating	Pitch, rows, positions, plastic height, mating height and plating

RFQ notes

For both structures, confirm pitch, total positions, plastic height, terminal tail length, straight or right-angle orientation and plating. If the mating connector is fixed, send its drawing or sample photo so insertion depth and stack height can be reviewed.
