Breakaway header, 18 circuits, 3 A
The 9-146253-0-09 is the 18-circuit member of TE's AMPMODU Mod II breakaway header line, a dual-row unshrouded header on 0.100" (2.54 mm) pitch. Rated 3 A per contact with gold-plated mating surfaces (30.0 µin) and tin-plated posts, it suits board-to-board or cable interconnect duty within a -65°C to 105°C operating range.
Pitch, footprint, and board fit
The 0.100" (2.54 mm) row spacing matches the pitch, so the footprint occupies a standard 0.100" x 0.100" grid — a common layout for prototyping and production boards. Unshrouded push-pull fastening and a UL94 V-0 LCP insulator keep the header suitable for open-board environments where the mating half is keyed separately.
