15-position, 3-row, 4.14 mm pitch header with locking ramp
The 1-770190-1 is a vertical through-hole header from the Mini-Universal MATE-N-LOK series, carrying 15 male pin contacts in a 3-row arrangement on a 0.163-inch (4.14 mm) pitch. Rated for board-to-cable/wire applications, it is intended for general-purpose use where a secure, keyed connection between a PCB and a wire harness is needed.
It is ROHS3 compliant and supplied in bulk packaging.
Comparison with 1318699-3: row count and pitch delta
The closest peer in the same family is the 1318699-3, a 4-row, 12-position header with a 0.165-inch (4.20 mm) pitch and a latch lock instead of a locking ramp. If your BOM calls for 15 positions in a 3-row layout, the 1-770190-1 fits; if you need 12 positions in 4 rows, the 1318699-3 is the match. The pitch difference (0.163" vs 0.165") is small but the row count and position count are the deciding factors — confirm your mating receptacle's cavity layout before switching.
