1.00 mm pitch, 30-position SMT header with latch hold
The 5011903027: This is a Molex Pico-Clasp 501190 series header, 30 positions loaded, dual rows at 1.00 mm mating pitch with a row spacing of 2.66 mm. The shrouded 4-wall design and latch holder fastening keep the mated pair locked against vibration — useful for portable or moving assemblies where a loose connector means a field return. The SMT termination with solder retention and a pick-and-place feature suits automated assembly lines. Insulation height is 5.40 mm, and the mated stack height is 6.8 mm — check your board-to-board clearance if you're stacking mezzanine, though this is a wire-to-board part.
