The Amphenol FCI 10147520-144-THLF is a 144-position header from the Bergstak® FX10 0.5mm series, designed for board-to-board mezzanine stacking. The connector is surface-mount with integrated board guide, pick-and-place cap, and solder retention features, making it compatible with standard SMT reflow lines.
Stacking Height and Board Fit
The mated stacking height is 6mm, with the header itself standing 5.30mm above the board. The 0.50mm pitch drives a dense footprint: 144 circuits in two rows means the board layout needs careful routing, especially for differential pairs or high-speed signals.
Comparing Stack Heights Within the FX10 Family
The same-series sibling 10147520-144-SHLF shares the same 144-position count, 0.50mm pitch, and 30.0µin gold plating, but its height above board is 3.50mm instead of 5.30mm. That difference translates to a lower mated stack — roughly 4mm versus 6mm — which matters when the z-height budget in the enclosure is tight. Both are active and use the same footprint, so swapping between them is a board-layout decision, not a re-spin.
