Compared to the 1394090-1 (also a 9-position, 2.54mm pitch AMPMODU Mod II header), the 280508-2 uses a detent lock fastening instead of a friction latch — the detent provides a more positive tactile feel during mating. The 1-292164-1 is a 10-position version of the same series; if your BOM calls for 9 circuits, the 280508-2 is the exact fit without leaving an unused position.
The pitch is 0.100" (2.54mm), which is the standard spacing for AMPMODU Mod II and most 2.54mm IDC cable assemblies.
Yes, it has a 3-wall shrouded housing that protects the pins and guides the mating receptacle during assembly.
The 1394090-1 is a 9-position, 2.54mm pitch AMPMODU Mod II header with a detent lock — it is the closest functional alternate within the same series.
