The current rating is not a fixed number but varies by wire gauge and ambient temperature. In practice, with 22 AWG wire and a 30°C rise, the contact can handle about 5 A per circuit, but the derating curve in the MTA-100 application note should be checked for your specific load and temperature.
The 4-644456-2 is a 12-position version of the same unshrouded header. For an 11-position replacement, the 4-644456-1 itself is the only member with that exact position count in the MTA-100 unshrouded line.
The 4-644456-2 has 12 positions; the 4-644456-1 has 11. All other specs — pitch, plating, termination, insulation material — are identical.
