Compared to the 1-292164-1 (CT series, 0.079\" pitch, 11 positions, detent lock, right-angle), the 644752-6 offers a wider 0.156\" pitch for easier routing and a friction lock instead of a detent — the lock style difference matters for the mating housing retention feel. The 644752-6 also carries a 600VAC rating vs 125VAC on the CT part, making it the choice for line-voltage circuits. Against the 953440-3 (0.100\" pitch, 6 positions, dual-row, right-angle, automotive), the 644752-6 is single-row and vertical, which simplifies board layout for a 6-circuit interface but takes more board edge space per circuit. The 953440-3's 12V rating limits it to low-voltage automotive; the 644752-6's 600VAC suits industrial power.","metaTitle":"644752-6 TE Connectivity MTA-156 Header, 6 Pos, 3.96mm Pitch","metaDescription":"644752-6 TE Connectivity AMP MTA-156 header, 6 positions, 0.156\" pitch, tin-plated, friction lock, UL94 V-0, active.
