3-position, 2.50 mm pitch, single-row header for wire-to-board
The 5-1376492-3: This is a 3-circuit, single-row header from TE's Signal Mate series, designed to connect a cable assembly to a PCB.
How this header compares to CT and .025 series peers
The 1394090-1 from TE uses a 2.85 mm pitch and comes in a 6-position black housing with thicker 39.4 µinch tin plating on both contact and post. That thicker plating buys more corrosion margin in humid environments, but the wider pitch means a different footprint and a different mating receptacle family.
