It uses the standard 3.00mm pitch that matches the full Micro-Fit 3.0 ecosystem — same footprint as the original Micro-Fit 3.0, so board layouts and mating headers carry over. Two rows of 2 positions each keep the harness bundle compact.
The listing carries a critical note: contacts are not included. The mating half is a Micro-Fit 3.0 or Micro-Fit+ male header with 4 circuits, 2 rows, 3.00mm pitch, through-hole or surface-mount. No secondary TPA retainer on this 4-position version, but the primary latch holds well under vibration when the terminals are fully seated.
