The 640453-4: The mating pin length is 0.295" (7.49mm), which engages fully with the receptacle contact beam. All 4 positions are loaded; the square male pins are copper alloy with tin finish.
The 640453-4 is unshrouded, 4 positions, and uses the wider 0.100" pitch; the choice depends on whether the application needs polarised shrouding and a locking latch for vibration resistance.
The 1-292164-1 from the CT series is a right-angle through-hole header with a shrouded 4-wall design and detent lock, but it has 11 positions on a 0.079" pitch. The 640453-4 is unshrouded with 4 positions on a 0.100" pitch — the best alternative depends on whether you need shrouding and a locking latch.
