For a harness designer, this means the 8-position header can carry signal-level loads or moderate power, but the per-circuit current must be derated based on the wire size and ambient temperature. ## Peer Comparison: 1-292164-1 The closest functional second-source is the TE CT series header 1-292164-1, which is also a single-row unshrouded header but with an 11-position count on a tighter 0.079\" (2.00mm) pitch and a right-angle orientation. Its voltage rating is 125 VAC, half this MTA-100's 250 VAC. If your board layout and BOM allow 2.00mm pitch and need more circuits, that part is a viable alternative; if you need the 2.54mm pitch or the full 250 VAC rating, stick with the MTA-100.","metaTitle":"3-644695-8 TE MTA-100 Header 8 Pos 2.54mm Pitch","metaDescription":"TE MTA-100 unshrouded header, 8 positions, 0.100\" (2.54mm) pitch, tin-plated contacts, through-hole, UL94 V-0.
