18-Position Breakaway Header in the KK396 Family
The 0026481181: This is a Molex KK396 41661 series unshrouded breakaway header, 18 circuits in a single row on 0.156" (3.96mm) pitch.
With 18 positions all loaded, the header spans about 2.8" (71 mm) across the board.
As an unshrouded header, it mates with standard KK396 crimp housings — the most common match is a Molex 41661 series receptacle housing that accepts 18 circuits. For a locked connection, use the shrouded version (different base number). The square male pins (0.045" square typical for KK396) accept the female crimp terminals from the same series.
The insulator is glass-filled polyester, giving dimensional stability through wave solder.
