Breakaway header, 27 positions, 2.54 mm pitch
The 4-103321-0-27 is the 27-position member of TE's AMPMODU Mod II breakaway header line, a single-row unshrouded male pin header on 0.100" (2.54 mm) pitch. Rated 3 A per contact with tin-lead plating on both the mating surface and the solder post, it operates from -65°C to 105°C and carries a UL94 V-0 thermoplastic housing.
Pitch, footprint, and operating range
The 0.100" (2.54 mm) pitch and single-row layout set the board footprint — the breakaway design allows snapping to the needed position count, though this part ships with all 27 positions loaded. Operating temperature spans -65°C to 105°C; the UL94 V-0 rated housing suits equipment inside an enclosure that requires a flame rating.
