It uses a 0.156" (3.96 mm) pitch, which sets the PCB footprint spacing and ensures compatibility with the matching KK396 header.
The 0.156" pitch matches the standard KK396 header footprint and provides creepage distance for the 600 V rating. The 4.5 A per-circuit rating is the headline current; derate above 105 °C per the manufacturer's curve. The locking ramp gives an audible tactile click when fully mated, confirming positive engagement — a detail that matters in production-line assembly and field service.
It is ROHS3 compliant.
