16-Pin Right-Angle Breakaway Header, 2.54 mm Pitch
Mating length is 0.324" (8.23 mm) — enough to engage a standard KK254 crimp receptacle or IDC socket housing. Mates with Molex KK254 series crimp housings (e.g., 6471 series) or 4455 series IDC receptacles using 0.025" square female contacts. The unshrouded design means no polarisation key — verify pin 1 orientation against the PCB silkscreen during assembly.
No official successor or pin-compatible cross-reference is listed. The KK254 series includes multiple breakaway variants with the same pitch but different pin counts and orientations — the 16-position right-angle version is the exact fit for this BOM line.
