Board footprint and signal density
The 5499913-2: For a 14-position header carrying 1 A on every pin, the total current through the connector is 14 A, but the thermal budget is shared across the body; in practice, derate if all circuits are loaded simultaneously in a high-ambient enclosure.
Mating and retention for wire-to-board harnesses
The latch lock/eject hooks are short, meaning they engage the mating receptacle's latch ears for a positive lock but still allow tool-less release when you squeeze the eject tabs. The post finish is tin with 100 µinch thickness, which solders reliably into plated through-holes without additional surface prep.
The closest functional alternative in the same right-angle, shrouded header family is 1-1871673-2 — but that part is a 4-position, 0.098" (2.50mm) pitch version with tin mating finish and a detent lock instead of latch/eject hooks. The 5499913-2 gives you 14 positions at 2.54mm pitch with gold mating finish and eject hooks; the 1-1871673-2 is a lower-density, lower-cycle-life option for a 4-wire harness where the board space is tighter.
