4.14mm pitch header with 30µin gold mating surface
A locking ramp on the housing provides audible feedback on full engagement and resists vibration-induced separation.

How the 770875-2 compares to the 1318699-3
The closest peer in the ledger is the 1318699-3, a 12-position, 4-row header with a 4.20mm pitch and latch-lock fastening. The 770875-2 has 6 positions in 2 rows at 4.14mm pitch with a locking ramp — the pitch difference (4.14mm vs 4.20mm) is negligible for board layout, but the 4-row peer requires a wider board footprint. Both use gold mating finish, but the 770875-2's 30µin gold is ten times thicker than the 1318699-3's 3µin, giving the 770875-2 a significantly higher mating cycle rating for field-service applications.
