Board Footprint and Stack Height — What the Pin Lengths Mean
The 10076801-101-28LF: The 0.230" mating length provides enough reach to engage a standard box-style receptacle fully, while the 0.098" post sits flush in a 1.6 mm PCB through-hole without protruding excessively on the solder side. Row spacing is also 0.100" (2.54 mm), so the dual-row footprint is a 2×14 grid on a 2.54 mm square matrix. This matches the vast majority of 0.100" pitch dual-row receptacles on the market.
The base product number is 10076801, and the full suffix 101-28LF encodes the plating option (30 µinch gold), the 28-position count, and the RoHS compliance.
