The 499206-1 is a 10-position, 2-row, 2.54 mm pitch header from TE's AMP-Latch series, designed for board-to-cable/wire connections.
At 1 A per contact, the 499206-1 is suited for low-current signal paths — think control lines, data buses, or sensor inputs.
Mating connector and field-service fit
This header mates with a standard AMP-Latch IDC receptacle. The keying slot on the header aligns with the receptacle's keying rib; a non-keyed receptacle will still mate, but the slot is there for polarization. For field re-pinning: the header is through-hole soldered — not a crimp-in terminal. If the header fails on the board, it's a desolder-and-replace job, not a pin swap. The mating receptacle uses crimp terminals that can be re-pinned on site with a basic tool.
