The 57202-G52-10LF: The SMT termination and push-pull fastening mean the header reflows with the board and holds the receptacle by friction alone — no secondary latch.
The 26-position 57202-G52-13LF is the next step up in the same series — same pitch, same plating, same current — but adds six more circuits for a wider board interface.
No through-hole posts to clinch, so the board-side footprint is just the pad pattern and the alignment pegs (if present) handle shear during the mating cycle.
