The 1-wall shrouding provides basic polarization and protects the mating pins during handling, but does not fully enclose the contact area — a 4-wall shroud offers more protection against misalignment during blind mating. No stock-holding claim is made. ## MTA-156 Series Compatibility This header mates with standard MTA-156 receptacle housings and accepts the corresponding crimp terminals (20-24 AWG typical). The 0.156\" pitch and single-row layout are consistent across the series, making the 3-644611-2 a drop-in replacement for any 2-position MTA-156 header requirement.","metaTitle":"3-644611-2 TE Connectivity MTA-156 Header, 2 Pos, 3.96mm","metaDescription":"Active-production TE Connectivity MTA-156 header, 2 positions, 0.156\" pitch, tin-plated contacts, friction lock.
