The Dubox™ series offers the same 11.04 mm stack height and 0.100\" pitch in 22-position (71991-311LF), 24-position (71991-312LF), and 26-position (71991-313LF) variants — all with identical gold plating and through-hole termination. If the BOM requires more I/O, the 22-position version is a direct drop-in for the same footprint width, while the 24- and 26-position versions widen the board layout.","metaTitle":"71991-310LF Amphenol ICC Dubox™ 20-Pin Female Socket Header","metaDescription":"71991-310LF board-to-board receptacle, 20 positions, 2.54 mm pitch, 30 µinch gold mating finish, 11.04 mm stack height.
