For a 2-position header, the per-contact current is typically derated from the terminal's rating based on the number of adjacent circuits and ambient temperature. The tin-plated contacts have a higher contact resistance than gold, which increases self-heating at higher currents. In a 2-position configuration, the thermal rise is lower than in a multi-position header, but the wire gauge must still be matched to the load to stay within the UL temperature rise limits. ## Peer alternatives for cross-shop evaluation The closest functional alternative is the 1-292164-1 from the CT series — also a shrouded header with friction lock, but with 11 positions on a 0.079\" (2.00mm) pitch. The 640445-2 offers a wider 3.96mm pitch and a lower position count, which may simplify routing for power or high-voltage signals. The 1-1871673-2 (1871673) is a 4-position, 2-row, 0.098\" (2.50mm) pitch header with board lock and detent lock. It provides a different footprint and retention mechanism, useful when board-lock anchoring is required for reflow or vibration resistance. The 1379030-3 is a 12-position, 2-row, 0.100\" (2.54mm) pitch header with friction lock and mounting flange. It targets higher-density board-to-wire applications where a flange provides additional mechanical stability.","metaTitle":"640445-2 TE Connectivity MTA-156 Header 2 Pos 3.96mm Pitch","metaDescription":"640445-2 TE Connectivity AMP Connectors MTA-156 header, 2 positions, 0.156\" (3.96mm) pitch, tin-plated contacts, friction lock.
