Board footprint and mating interface
The 20021511-00016T4LF: This is a 16-position, dual-row header on 1.27mm pitch — the board footprint matches a 2×8 layout with 1.27mm row spacing. The 0.091" (2.30mm) solder post length suits standard through-hole boards; the 0.213" (5.40mm) insulation height leaves clearance for mating receptacle housings.
Keying and housing compatibility
The header includes a keying slot — this prevents mismating with receptacles that lack the corresponding key.
