In a ribbon-cable application where the connector mates once at assembly and stays mated, gold flash is adequate. The solder posts are tin-plated (100 µinch) and measure 0.125\" (3.18 mm) long—standard for a 1.6 mm PCB. The through-hole termination gives a strong mechanical anchor; the board guide and keying slot in the housing prevent misinsertion during assembly. The standard package is tube; no reel or tape options are listed for this MPN. ## Peer Comparison: 1-1871673-2 vs 1888193-4 No direct drop-in replacement exists between the two.","metaTitle":"TE AMP-Latch 1888193-4 Header – 20 Pos, 2.54 mm Pitch","metaDescription":"TE Connectivity AMP-Latch 1888193-4 – 20-position, 2-row, 2.54 mm pitch shrouded header.
