It uses a 0.100" (2.54mm) pitch on both rows and contacts, with a 0.100" row spacing, making it a standard footprint for many ribbon-cable and mezzanine applications.

Position count contrast within the 146134 base
Compared to sibling MPNs sharing the same 146134 base product number and identical specs (pitch, plating, material, mounting), the 2-146134-1 carries 30 positions. The 1-146134-9 offers 16 positions, the 1-146134-8 offers 14, and the 1-146134-7 offers 10 — all in the same dual-row SMD format. The choice is purely position count for the PCB footprint.
