The 640638-3 is a 26 AWG socket contact in TE's MTA-100 series, terminated by IDC — no stripping or crimping tool needed.
Within the MTA-100 series, the 640638-3 (26 AWG) sits alongside the 640637-3 (24 AWG) and the 640636-3 (22 AWG) — all share the same IDC termination, tin plating, and bulk packaging, so the choice narrows to wire gauge.
The 640638-3 is a 26 AWG socket; the 640637-3 is a 24 AWG socket. Both are MTA-100 IDC contacts with the same tin plating and termination, but the wire gauge differs — the panel would need 26 AWG wire to accept the 640638-3.
