What the 0.156" Pitch Means for Your Board
The 1-640383-6: This is a 16-position, single-row unshrouded header from the MTA-156 series, with a mating pitch of 0.156" (3.96 mm). This covers most indoor industrial and general-purpose equipment, but the 105°C ceiling means it's not suitable for engine-compartment or high-heat environments.
The 0.156" pitch and 0.400" (10.16 mm) mating pin length ensure full contact wipe with the receptacle terminal. Termination is solder only—no press-fit option.
ROHS3 compliant.
The key difference: this MTA-156 part has 16 positions at 3.96 mm pitch versus 11 positions at 2.00 mm—the wider pitch means larger board footprint per circuit but simpler routing and higher current capacity per pin.
