0.100" pitch, 5-position board-to-board receptacle
The receptacle accepts either bottom or top entry, meaning it can be loaded from either side of the board depending on the stack orientation. Through-hole solder tails (0.120" post length) anchor the part mechanically before wave solder.
Gold mating finish for reliable cycling
The mating contact surface carries 31.5 µinch (0.80 µm) gold over the copper alloy base, with tin on the solder posts (118.1 µinch / 3.00 µm). Gold on the mating face buys you a minimum of several hundred mating cycles — suitable for test fixtures, programming jigs, or any board-level interconnect that sees periodic reconnection.
No official cross-reference or equivalent part number is listed by TE, so confirm the mating header's pin count and pitch match before committing the board layout.
