The 2.50mm pitch gives a compact footprint while keeping enough spacing for moderate current per circuit, and the dual-row layout saves board edge space compared to a single-row equivalent.
The 2.50mm pitch (0.098") sets the board hole pattern if you're using a through-hole header — verify your PCB layout against this spacing. The 12 circuits match the BOM line count.
Contacts Are a Separate Order — Don't Get Caught Short
Ordering only the housing leaves you with an empty shell and a stalled assembly line. Factor the terminal part number into your BOM alongside this housing.
