The housing is moulded for 14 positions, but only 11 are loaded with tin-plated square pins — a selective-population variant that saves cost when the full circuit count isn't needed. ## Tin-on-tin contact finish and current derating Tin-on-tin contacts are rated for fewer mating cycles than gold, but they carry adequate current for general-purpose and industrial use when the wire gauge is matched to the load. The through-hole pins are 0.125\" (3.18mm) long, with an overall contact length of 0.650\" (16.51mm). The shrouded 1-wall design protects the pins from one side and guides the mating receptacle — mates with standard MTA-156 crimp housings that carry the friction-lock ramp.","metaTitle":"643710-7 TE Connectivity MTA-156 Header 14 Pos 3.96mm Tin","metaDescription":"643710-7 TE Connectivity AMP Connectors MTA-156 header, 14 positions (11 loaded), 3.96mm pitch, tin-plated contacts, friction lock, UL94 V-0.
