The Amphenol 91276-429HLF is a 29-position unshrouded BergStik® II header, single-row, on the standard 0.100" (2.54 mm) pitch. The 5 A per-contact rating and 110 V voltage limit suit it for signal-level and low-power distribution inside an enclosure.
The key selection axis here is position count: 29 positions against the more common 10, 20, or 36-position members. If your BOM calls for 29 circuits, this is the direct fit; a 36-position header would leave seven unused pins on the same footprint.
That's fine for a stable board-to-board stack where the connectors are aligned by the board mounting, but it's less forgiving in a free-cable application.
