12.40 mm pitch power header for board-to-cable wiring
Its defining footprint spec is the 0.488" (12.40 mm) pitch — a wide stance that gives generous clearance for power wiring and keeps creepage distance up at 600 VAC.
Rated 600 VAC, with a UL94 V-0 glass-filled nylon 6/6 housing that handles -30°C to 105°C. The rectangular tab contacts accept the matching GHC crimp terminal; the 4-wall shroud guides the plug home and prevents misalignment. For a 2-position part, the latch lock and board lock together mean the assembly can handle the cable strain of a power harness without the header lifting off the board.
The 1747996-1's 12.40 mm pitch is over 4× wider — a completely different footprint for power vs signal duty. The 2-position count and board lock on the 1747996-1 are the other clear differentiators.
