What This 8-Pin Breakaway Header Does
It breaks away from a longer strip, so you can snap off exactly 8 pins for a custom board-to-board or cable interconnect.
The 9-103323-0-08 offers 8 positions vs 6, uses the standard 0.100" pitch, and carries a lower 3 A rating vs the 1394090-1's unspecified current. The key difference is the shroud: the 1394090-1 provides pin protection and a latch for vibration resistance, while the 9-103323-0-08 is unshrouded and push-pull — simpler to mate but less robust in high-shock environments.
