The 78229-103HLF: The through-hole termination supports either press-fit or solder assembly. Press-fit avoids the thermal stress of reflow on the board and is common in backplane builds where rework access is limited; solder tail gives a standard wave-solder process for lower-cost production.
Compare with the sibling 69190-202HLF, which carries 15.0µinch gold and is better suited for low-cycle, cost-sensitive builds.
