1.25 mm pitch, 15 positions, right-angle — what this HPI header does
The 1-1734829-5 is a 15-position, single-row header from TE's High Performance Interconnect (HPI) series, built for board-to-cable/wire applications where space is tight. Its 1.25 mm pitch packs 15 circuits into a compact footprint, but the trade-off is a 1 A per-contact rating — this is a signal-level header, not a power interconnect.
At 1 A per contact, this header is matched to low-current signal circuits — think sensor inputs, control signals, or low-power data lines. The 15-position count is a specific BOM line; verify the mating half matches exactly.
