Mating Compatibility and Termination Details
The 68491-446HLF: The male pins are square, 0.025" (0.64mm) square typical for this pitch, and the 0.255" (6.48mm) mating length provides good wipe inside a standard 2.54mm female socket. The phosphor bronze contact material gives good spring properties for repeated insertion.
The part ships in a bag, not bulk tube or tape-and-reel — factor that into the pick-and-place handling if you are using automated assembly.
The closest peer in the same series is the 67996-432HLF — a 32-position header with identical pitch (0.100"), row spacing, tin finish, and 3 A rating. The difference is purely position count: 46 positions versus 32.
