Board Layout and Routing with 6.35mm Pitch
The 643234-1: Six circuits in a single row means the header occupies a narrow strip on the PCB, leaving room for adjacent components or routing channels.
The base product number 643234 covers this and related variants — confirm the specific suffix for your application.
How This Compares to Peer Options
Compared to the 1-2823056-2 (12 positions, 0.100" pitch, surface-mount), this header offers a wider 6.35mm pitch and through-hole termination — the larger pitch suits higher-current or larger-gauge wire, while through-hole gives stronger solder joint shear strength.
