The 9-146256-0-03: Pitch is 0.100" (2.54mm) on both rows, matching the industry-standard 0.100" grid. The square male pins are 0.230" (5.84mm) long on the mating side, with a 0.120" (3.05mm) solder tail for through-hole boards. The post finish is tin, 100 µinch thick, for reliable solder wetting.
Sizing the Footprint and Routing
At 0.100" pitch, the board footprint is straightforward: two rows of 0.040" square holes on 0.100" centres, with 0.100" row spacing.
Available in bulk packaging.
How It Differs from a Shrouded Sibling
The key difference: the 953440-3 uses tin-plated mating contacts (vs gold on the 9-146256-0-03) and is rated for automotive applications with a 12 V voltage spec. The 9-146256-0-03 is unshrouded and gold-plated — better for signal-level circuits where repeated mating and corrosion resistance matter more than vibration-proof latching.
