The F51H-1A7H1-11004-B100: This is an Amphenol ICC (FCI) Aorora F51H series FFC/FPC connector with a 0.039" (1.00mm) pitch and 4 positions. It accepts a notched 0.33mm thick flat flex cable and terminates via solder to the board surface.
How It Compares — 4 vs 6 vs 7 Positions in the Same Series
The F51H-1A7H1-11004-B100 (4 positions) shares the same 1.00mm pitch, 0.5A rating, gold flash, solder retention, and 20 mating cycles with the 6-position F51H-1A7H1-11006-B100 and the 7-position F51H-1A7H1-11007-B100. If you need more mating cycles (30 vs 20) or a slide-lock actuator, the F51W-1A7H1-11010 in the Aorora F51W series offers those upgrades at 10 positions, same pitch and current. The trade-off is a slightly taller stack height (0.167" / 4.25mm vs 0.165" / 4.20mm).
Cable Fit and Termination Checklist
This connector accepts a notched FFC or FPC cable with a thickness of 0.33mm. The vertical, one-sided contact design means the cable inserts from above and contacts only the top side. The gray actuator locks the cable in place without a ZIF mechanism — insertion is straightforward but requires the correct cable end type. Termination is solder-only — the surface mount pads on the board must match the 1.00mm pitch footprint. The solder retention feature adds mechanical hold during reflow, reducing the risk of misalignment. No crimp tool or press is needed.
