What this 1.00 mm pitch header does that a 2.00 mm can't
The 1-1734709-0 is a 10-position, single-row header from TE's High Performance Interconnect (HPI) series, built for board-to-cable/wire connections. Its 1.00 mm pitch packs more signals into a narrower board footprint than the 2.00 mm pitch on the CT series peer 1-292164-1 — a direct density advantage for space-constrained layouts. Solder retention features hold the part steady during reflow, preventing the header from floating off the pads.
Where the 1 A rating draws the line
It is not a power header; the.025 series peer 1376366-8 carries 5 A per contact at a wider 2.20 mm pitch, a better fit for higher-current board-to-wire runs. The 50 V rating and tin-on-tin contact finish with 120.0 µin thickness suit moderate environments with standard mating cycles.
