The 0.290\" (7.37 mm) mating pin length provides sufficient engagement depth for standard MTA-100 receptacles; the 0.347\" (8.81 mm) insulation height leaves clearance for wire strain reliefs above the housing. Rated 250 VAC; current varies by wire gauge and is limited by the pin cross-section, not the housing. ## Cross-shop alternatives in the same pitch family Peer 1379030-3 offers 12 positions in a 2-row, 0.100\" pitch configuration with board lock and mounting flange — suited for higher-density board-to-wire connections where the single-row 3-647166-4 does not fit.","metaTitle":"3-647166-4 TE MTA-100 Header, SMD 4-Pos 2.54mm Pitch","metaDescription":"Active production 3-647166-4 TE MTA-100 4-position SMD header, 0.100\" pitch, friction lock, UL94 V-0.
