Right-angle through-hole breakaway
The 4-103330-0-26 is the 52-position member of TE's AMPMODU Mod II unshrouded header line, a breakaway style that lets the board builder snap the strip to the exact circuit count needed on site. It carries tin-lead plated square pins rated 3 A per contact, mounts through-hole right-angle, and mates with any AMPMODU Mod II receptacle at the same 0.100" (2.54 mm) pitch.
Dual-row routing density
The two rows sit on 0.100" (2.54 mm) row spacing — the same pitch as the contact-to-contact spacing — which keeps the board footprint regular and the routing channels predictable for a 52-position connector.
