The unshrouded design means it mates with standard AMPMODU receptacles without keying or a locking latch — a push-pull fastening that suits low-vibration environments where the connector won't see mechanical shock or cable strain. While this is a thin flash — not a heavy gold layer — it still provides corrosion resistance and a reliable connection for moderate mating cycles. The post finish is tin at 98.4µinch (2.50µm), which solders well into through-hole boards.
The 1379030-3 and 953440-3 are both right-angle, shrouded headers with friction locks and tin mating finish, designed for automotive applications at 12 V. The 825440-8 is a straight, unshrouded header with gold finish — a different mechanical and electrical fit. No direct replacement.
