The 10114829-10108LF: The 0.049" (1.25 mm) pitch is the first decision point for the board layout: it sets the pad spacing and the trace channel width between rows. In a harness assembly where the receptacle is plugged blind, the shroud guides the mate and prevents bent contacts — a common failure in unshrouded headers. For power distribution above 1 A, step up to a 2.00 mm or 2.54 mm pitch header with gold plating.
The 10114829 series includes 4-position (10114829-10104LF), 5-position (10114829-10105LF), 6-position (10114829-10106LF), and this 8-position variant.
This is a through-hole solder header — the 0.091" (2.30 mm) post length fits standard 1.6 mm PCBs with enough protrusion for a reliable solder fillet. The detent lock mates with a corresponding receptacle (not included) and gives audible feedback when fully seated.
