Rated at 600 VAC, the header suits general-purpose and industrial equipment where the working voltage stays below that ceiling. If you are designing a new board, look at the current MTA-156 product line for a form-fit-function replacement; the 0.156\" pitch and 12-position count are common, but verify the shroud height and lock style against your mating housing. For an existing BOM, confirm the mating half and the contact finish before committing to a surplus buy. The header mates with MTA-156 receptacle housings that accept 18–24 AWG wire via IDC termination — the friction lock snaps into the matching slot on the receptacle. The square male pins (0.045\" typical for MTA-156) are copper alloy with a tin-lead finish.","metaTitle":"1-647123-2 TE Connectivity MTA-156 Header 12 Pos 0.156\"","metaDescription":"1-647123-2 TE Connectivity AMP Connectors MTA-156 series shrouded header, 12 positions, 0.156\" pitch, through-hole, friction lock.
