3-position breakaway header, unshrouded
The 4-103321-5 is the 3-position member of TE's AMPMODU Mod II breakaway header line, configured as a single-row unshrouded male pin header with push-pull fastening. Rated 3 A with tin-plated mating contacts (100.0 µin thickness) on a 0.100" (2.54 mm) pitch, the header operates from -65°C to 105°C and carries a UL94 V-0 thermoplastic housing.
What the specs mean for board fit
The 0.100" pitch and single-row layout match the standard AMPMODU Mod II footprint — the unshrouded design leaves the solder tails exposed for inspection and rework. Tin-on-tin mating contacts at 100.0 µin thickness suit moderate-cycle-count applications where cost per position is a factor; the 3 A rating is typical for signal-level circuits on a 0.100" pitch.
