Board Fit and Pitch Reality
The 1-1734598-0: This is a 10-position, single-row, through-hole header with a 1.25 mm pitch — the board footprint is compact, about 11.25 mm wide across the row. At this pitch and current, the connector is suited for signal-level interconnects in automotive, industrial, and medical equipment — not for power distribution.
Temperature and Application Envelope
The UL94 V-0 glass-filled PA9T housing holds its shape through wave solder and resists flame spread inside an enclosure.
RoHS compliant. No official cross-reference or pin-compatible alternative is listed — the 1.25 mm pitch and 10-position count are specific to this HPI series member.
