Through-hole header with locking ramp
The 1-1971839-5 is the 5-circuit member of TE Connectivity's shrouded header line for board-to-cable/wire applications. It carries silver-plated mating contacts on a 2.50 mm pitch, terminates via through-hole solder, and includes a locking ramp for secure mating with a receptacle housing.
Single-row, 5-position footprint
The 1-1971839-5 uses a single-row layout with 5 positions loaded, all positions populated, at a 2.50 mm pitch. The 4-wall shrouding and locking ramp are shared across the series — match the position count to the circuit count; the footprint and pitch are consistent.
