Board layout footprint: 1.50 mm pitch and hybrid mounting
The 2106091-2 is a 3-position, single-row header from TE's Mini CT series with a 0.059" (1.50 mm) mating pitch. Mounting is Surface Mount, Through Board — the header sits on SMT pads for the signal connections and has through-board posts for solder retention, giving better mechanical hold than a pure SMT part without requiring a full through-hole wave process.
Mating half and termination: what fits this header
This is the male pin header half of a wire-to-board connection — it mates with a Mini CT receptacle housing (crimp terminals sold separately). The detent lock compensates for tin's tendency to fret under vibration. For a 1.50 mm pitch header with tin contacts, expect a typical derated current around 2-3 A per circuit; confirm with the terminal datasheet.
Packaging options include Tape & Reel and Cut Tape — the SMT/through-board hybrid footprint is compatible with standard pick-and-place, but the through-board posts may require a secondary insertion step or a selective solder process.
