In a production harness build, that's fine; in a field swap, double-check the keying on the mating half before you seat it. ## Gold-Plated Mating Contacts and Through-Hole Terminals The mating contacts are gold over nickel (15.0µin gold), while the solder tails are tin-plated (118.1µin). That's a common split: gold where the wiping action happens, tin on the post for a reliable solder joint. The 0.114\" post length fits standard 1.6mm PCBs without bottoming out. The square pin profile mates with standard C-Grid III crimp sockets.","metaTitle":"Molex 0901310773 C-Grid III 90131 Header – 26 Pos, 2.54mm","metaDescription":"Molex 0901310773 – C-Grid III 90131 series, 26-position unshrouded header, 2.54mm pitch, gold-plated mating contacts.
