What pitch and pin count does 1744489-7 carry?
This is a 7-position, single-row header on 0.156" (3.96mm) pitch — the board footprint matches a standard 3.96mm centerline, and all 7 positions are loaded. The 3.96mm pitch provides enough creepage for the 250VAC rating, making this header suitable for general-purpose industrial and lighting circuits without tracking concerns.
Shrouding and locking — what does it mean for the fit?
Shrouded on one wall — the plastic shroud surrounds the pins on one side, protecting them during handling and guiding the mating receptacle into alignment. The mating half is a TE Economy Power receptacle housing (series: Economy Power) with crimp terminals — the friction lock is the primary retention; no secondary lock is present, so the terminal pull-force depends on the crimp quality and the receptacle's terminal retention.
Current and voltage — where does this header fit?
Rated 7.5A per contact at 250VAC — this is a power-signal connector, not a high-current busbar.
Glow wire compliance — why it matters
This header is Glow Wire Compliant per IEC 60335-1 — a requirement for household appliances and lighting fixtures where the connector must withstand a 850°C glow-wire test without igniting. The nylon (PA) housing material is formulated to pass this test.
