1.25 mm Pitch, 9-Position SMT Header — Board-Edge Signal Routing
The 1734261-9: This 9-position, single-row header from TE's HPI series uses a 1.25 mm pitch — tight enough for compact board-edge routing but wide enough to keep PCB trace escape manageable for signal-level circuits.
Tin Mating Finish and Solder Retention — Cost-Effective Assembly
The mating contacts are finished with 100 µin of tin over phosphor bronze — a thick, cost-optimized plating for moderate mating-cycle applications where gold is not justified.
It is ROHS3 compliant, meeting the current EU restriction directive for hazardous substances.
