Board-to-Board Sizing: 2.00 mm Pitch, 10 Circuits, Dual-Row
The unshrouded design gives you the option to snap the header to length for non-standard circuit counts before assembly. The gold mating finish (3.94 µinch over nickel) keeps contact resistance stable across repeated mating cycles — a solid choice for test fixtures or modular boards that get swapped quarterly.
Termination is through-hole solder. The contact length — post is 0.110" (2.79 mm), mating length is 0.157" (4.00 mm), overall length 0.327" (8.30 mm). The post length determines the PCB thickness it can fit; the mating length sets the stack height when paired with a receptacle. The square pin shape (0.64 mm typical for 2.00 mm pitch) provides a reliable solder joint and good shear strength.
RoHS3 compliant.
The closest sibling is the 2842138-6, which shares the same 10-position, 2.00 mm pitch, dual-row layout. The difference: the -6 variant carries a 15 µinch gold mating finish versus the 3.94 µinch flash gold on the -5. If your application demands more than 100 mating cycles, the thicker gold on the -6 is worth the premium.
