The 3-641211-4: The unshrouded male pins mate with standard MTA-100 crimp receptacles or IDC connectors — the same pitch family used across TE's MTA-100 wire-to-board system.
Tin on the solder tail keeps the board-side cost down.
For a given application, the per-contact current ceiling follows the derating curve of the chosen MTA-100 crimp contact and wire size.
The 3-641211-4 is sourced to order through independent distribution.
The pitch is 0.100" (2.54 mm), standard for the MTA-100 series.
Yes, it is RoHS3 compliant.
Within the MTA-100 series, the 4-position unshrouded header is the standard offering. No direct pin-compatible substitute from another series is listed on this record — confirm the mating half and board footprint before substituting.
