The unloaded position is a keying or polarization feature — confirm your harness pin count against the BOM. ## Tin plating, solder termination, and temperature range Both the mating and post contact finishes are tin. The bulk package is standard for this part. ## Peer comparison: 1-292164-1 and 953440-3 The 643494-4 offers a wider 0.100\" pitch and a friction lock at 250 VAC — a different footprint and locking mechanism.","metaTitle":"643494-4 TE Connectivity MTA-100 Header, 6 Pos, 2.54mm","metaDescription":"643494-4 TE Connectivity MTA-100 header, 6 positions (5 loaded), 0.100\" pitch, friction lock, tin plating, UL94 V-0.
