40-Position Dual-Row Shrouded Header for Board-to-Cable Wiring
Gold Mating Surface and 30 µinch Plating for Repeated Cycling
The mating contacts carry 30.0 µinch (0.76 µm) gold over nickel, while the solder tails are finished with 100.0 µinch (2.54 µm) tin.
RoHS compliant per the current lifecycle status.
Peer Comparison: 40-Position vs Lower-Density Alternatives
Compared to the 1318699-3 (12 positions, 0.165" pitch, 5 A, latch lock), the 3-1761603-3 offers over three times the circuit count in a denser 2.54 mm grid but at one-fifth the per-contact current. The 1318699-3 uses a latch lock for vibration resistance; the 3-1761603-3 uses push-pull fastening with a keying slot — choose the 40-position part when you need many signal lines in a single connector, and the 12-position part when each circuit carries higher current or the connection sees mechanical shock.
