The insulation height of 0.364\" (9.25mm) and black polyamide housing (UL94 V-0) suit it for densely populated boards where component clearance is tight. In a vibration-prone installation, the ramp alone keeps the mating receptacle seated; verify the mating half has a compatible latch feature. Available through independent distribution channels. The base product number 794631 may help locate similar headers in the same series, but each position count and plating variant is a distinct order code. The 3.00mm pitch and 0.118\" row spacing are consistent across the series, so a 12-position, 2-row receptacle with the same pitch will mate mechanically. The male pin contacts (square, gold-plated) require the matching female crimp terminal from the Micro MATE-N-LOK terminal family. Wire gauge selection determines the current rating — the header itself does not limit current below the terminal's capability.","metaTitle":"1-794631-2 TE Micro MATE-N-LOK Header 12 Pos 3mm Obsolete","metaDescription":"1-794631-2 TE Connectivity Micro MATE-N-LOK header, 12 circuits, 3.00mm pitch, gold-plated pins, locking ramp.
