10-Position 2mm Breakaway Header for Board-to-Board Stacking
The 1-2355181-0: Its 2.00mm pitch sets the PCB footprint — tight enough for dense routing but wide enough to keep per-contact current at 2A without excessive heating.
Board Fit and Stack Height Budget
Overall contact length is 0.327" (8.30mm) — the mating length of 0.157" (4.00mm) and post length of 0.110" (2.79mm) define the board-to-board stack height and the through-hole depth required on the daughter card. Insulation height of 0.059" (1.50mm) means the header body sits low above the PCB surface, leaving clearance for adjacent components on the board. The push-pull fastening type and unshrouded design allow easy manual mating and unmating, but the connector relies on the board-to-board alignment for strain relief — no secondary latch is present.
