The Hirose KN13C0.7-24DP-0.4V(800) is a 24-circuit, 0.016" (0.40mm) pitch header from the KN13C series, designed for board-to-board mezzanine stacking at a mated height of 0.7mm. The 0.40mm pitch places this in the fine-pitch category — the board footprint needs tight routing clearance and the pad layout must match the 0.40mm centerline exactly. Typical use is in compact portable electronics, handheld devices, and camera modules where the 0.7mm stack height saves vertical space inside the enclosure.
Key Ratings and the So-What for Your Fit
The 0.016" (0.40mm) pitch is the tightest in the KN13C line — it drives the PCB pad spacing and the routing channel width between pads. The 0.7mm mated stacking height sets the z-axis gap between the two boards; if your enclosure or mezzanine design calls for a different gap, this header won't fit without a board respin. For a permanent board-to-board interconnect that mates once and stays, this plating grade is appropriate.
