0.50 mm Pitch, 10-Position FFC/FPC — Signal-Level Interconnect for Tight Board Layouts
The F31K-1A7H1-11010: It terminates to a flat flex cable via vertical SMT solder pads, accepting both straight and tapered cable ends. The vertical orientation means the FFC enters perpendicular to the board, saving board-edge real estate compared to a right-angle part.
30 Mating Cycles and Gold Flash — Set-and-Forget Duty, Not Frequent Reconnect
The 30 mating cycle rating reflects the gold flash contact finish (1.97 µinch gold over phosphor bronze). This is a thin plating — adequate for a connector that mates once during assembly and stays mated for the product life, but not for a service loop that gets disconnected quarterly. This is a practical detail for the board assembly line — the connector stays put through the solder profile without shifting, and the retention tabs take the cable strain off the solder joints.
The base product number F31K-1A7H1 covers the series footprint; the -11010 suffix specifies the 10-position variant.
Peer Variants: 6, 12, and 24 Positions Share the Same Footprint Pattern
The 6-position F31K-1A7H1-11006 and 12-position F31K-1A7H1-11012 differ only in circuit count and cable end type (notched vs straight/tapered). The 24-position F31K-1A7H1-11024 also uses a notched cable end.
