Board-to-board mezzanine fit — 1.27mm grid, 10 positions, SMD
The 5-104656-1: This is a 10-position, dual-row header on a 0.050" (1.27mm) pitch grid, with the same 0.050" row spacing — so the full footprint is a 2×5 array of 1.27mm squares. It's a shrouded 4-wall header (the walls protect the pins during blind mating), with push-pull fastening — no latch, so it's best in applications where the mated boards don't see high vibration or repeated shock. That's a signal-level current — this is for low-power interconnects (data lines, control signals, sensor inputs), not power distribution.
This header mates with a matching AMPMODU 50/50 Grid receptacle — same 1.27mm pitch, same dual-row layout, same 8.13mm stack height. The 4-wall shroud aligns the receptacle before the pins touch, which helps in production assembly where the boards are mated blind. The applications listed include automotive, general purpose, medical, military, and telecommunications.
