3.96 mm Pitch, Right-Angle, Friction Lock — What That Means on the Bench
The 1744337-1: This is a 3-position header from TE's Economy Power series, but only 2 positions are loaded with contacts — the third cavity is empty.
Tin Plating and 250 VAC — Where This Header Fits
For frequent disconnect/reconnect, gold would be the better call. Rated 250 VAC, which covers standard single-phase industrial and lighting circuits.
How It Compares to Nearby Peers
Compared to the 1-292164-1 (CT series, 2.00 mm pitch, 11 positions, detent lock), the 1744337-1 has a wider pitch (3.96 mm vs 2.00 mm) and fewer positions (3 vs 11). The wider pitch gives more room for routing higher current traces, but the 1-292164-1 offers a denser footprint for signal-only applications. Against the 1376366-8 (.025 series, 2.20 mm pitch, 8 positions, latch holder), the 1744337-1 again has a wider pitch and fewer positions. The 1376366-8 carries a 5 A current rating and a latch holder for higher retention force. The 1-1871673-2 (1871673 series, 2.50 mm pitch, 4 positions, dual-row, detent lock) is a dual-row header with board lock features. The 1744337-1 is single-row and lacks board locks, so it relies on the solder joints alone for shear strength.
