Right-Angle Header for Board-to-Wire Power Distribution
The 640583-3 is a 6-circuit, single-row, right-angle through-hole header from TE's Universal MATE-N-LOK series.
Locking Ramp and Mounting Flange Hold the Mate Under Vibration
The mounting flange adds a screw-down option to the PCB for extra retention in high-shock environments.
The 1318699-3 is a 12-position, 4-row header with a 4.20 mm pitch, rated 5 A at 250 VAC — a higher-density, lower-current alternative. The 640583-3 carries twice the current per circuit (12 A vs 5 A) at a wider pitch (6.35 mm vs 4.20 mm) and higher voltage (600 VAC vs 250 VAC), and uses 30 µinch gold on the mating contact versus the 1318699-3's 3 µinch gold. The 640583-3 is a single-row, 6-position header; the 1318699-3 is a 4-row, 12-position header. The choice depends on board space and current per circuit — the 640583-3 suits a power rail, the 1318699-3 suits a signal harness.
