The 1-1734598-3: This 13-position single-row header uses a 0.049" (1.25mm) pitch, setting the board footprint and the receptacle it mates with. Tin-plated contacts (120.0µin on the mating face) suit moderate mating-cycle applications — expect several hundred cycles before wear-through, adequate for field-service or periodic harness replacement.
Material and Environment
The housing is glass-filled polyamide PA9T (UL94 V-0), rated for operating temperatures from -25°C to 85°C. This covers most indoor industrial and automotive cabin environments but not underhood or continuous high-heat zones. The natural (off-white) insulator colour is standard for the HPI series. Applications listed include Automotive, General Purpose, Industrial, and Medical — the PA9T material and tin plating are compatible with these sectors' typical thermal and chemical exposure, provided the connector is not subjected to direct washdown or corrosive atmospheres.
RoHS compliance is standard for TE Connectivity AMP Connectors headers of this era; the base product number 1734598 covers the family. The part ships in a tube.
