The shrouded 4-wall design and friction lock mean it mates positively with the matching MTA-100 receptacle housing and stays mated under vibration, unlike an unshrouded breakaway header that can walk loose. The 0.100\" (2.54mm) pitch and 8 positions are the first check against your PCB layout. The through-hole solder tails are 0.140\" (3.56mm) long, and the overall contact length is 0.440\" (11.18mm) — these dimensions matter for board thickness and clearance on the solder side. Compared to the 4-position, 2-row peer 1-1871673-2 (0.098\" pitch, detent lock, board lock), this 2-644861-8 is a simpler single-row friction-lock header with no board lock feature — a direct swap is not possible without changing the PCB footprint.","metaTitle":"2-644861-8 TE Connectivity MTA-100 Header, 8 Pos","metaDescription":"2-644861-8 TE Connectivity AMP Connectors MTA-100 shrouded header, 8 circuits, 0.100\" pitch, friction lock, UL94 V-0.
