0.40mm pitch, 6-position mezzanine plug for tight board stacks
With a 0.016" (0.40mm) pitch and a mated stacking height of 0.7mm, this connector fits into sub-millimeter gaps between parallel PCBs — typical for compact handheld devices, camera modules, or sensor boards where every tenth of a millimeter of z-height matters. The outer shroud contacts are gold-plated, and the dual-row arrangement packs six circuits into a narrow footprint. Surface-mount termination with pick-and-place and solder retention features means it runs through standard SMT lines without extra handling steps.
At 0.023" (0.59mm) above the board surface, the plug sits low enough that the 0.7mm mated stack height is determined almost entirely by the mating receptacle's profile. The 0.40mm pitch limits escape routing to micro-vias or very fine trace widths; expect to use at least one inner layer for breakout on dense designs.
Position count variants in the 503552 family
The 503552 series spans several position counts at the same 0.40mm pitch. The 6-position 5035520622 is the smallest member; there are also 10-, 16-, 20-, 24-, 30-, 40-, 50-, and 60-position variants. The board footprint scales linearly with position count — a 60-position version occupies roughly ten times the board edge of this 6-position plug. For a BOM requiring a specific circuit count, match the position count exactly; the pitch and stacking height are consistent across the series.
