The 3-644694-8: This header mates with MTA-100 IDC and crimp receptacles — the 0.100" pitch and 8-position count align directly with the matching receptacle housings.
No direct pin-compatible alternative is listed from TE within the same series, so stick with this order code unless you are respinning the board.
The mating pitch is 0.100" (2.54 mm), which is the standard MTA-100 spacing. This matches the footprint for all MTA-100 receptacles and most 0.100" pitch IDC connectors.
