The 1744428-5: The single-wall shrouding provides basic pin protection without adding bulk. Glow wire compliance and a UL94 V-0 nylon housing make this a candidate for lighting, appliance, and general industrial applications where flame-rated materials are specified.
Pitch, current, and the friction lock
At 3.96mm pitch, this header uses a wider contact spacing than the 2.85mm pitch of the 1394090-1 peer, which also has 6 positions and a 4-wall shroud with latch holder. The wider pitch here simplifies PCB routing for power circuits and allows a higher current rating per contact. The friction lock provides retention against vibration without a separate latch or latch holder, unlike the 1394090-1's latch holder fastening. This means the mating housing clicks in and holds with a simple push, but the lock is less robust than a positive latch for high-shock environments.
ROHS3 compliant.
