16 Circuits at 4.20 mm – Shrouded Header for Wire-to-Board
The 0039299167 is a 16-position, dual-row vertical header from the Molex Mini-Fit Jr 5566 series. It mates with Mini-Fit Jr receptacle housings (series 5557) for a wire-to-board connection. The through-hole termination keeps the solder joints visible for inspection, a preference in high-reliability assembly lines.
Tin Contacts – 35.4 µinch Plating for Moderate-Cycle Duty
Both the mating interface and the solder tails are tin-plated — 35.4 µinch (0.90 µm) on the mating face, 35.0 µinch (0.90 µm) on the post. For a field-service connector cycled quarterly, that is roughly 12 years of service at the contact interface before wear-through becomes a concern. The square brass pins (0.062-inch typical cross-section) carry the rated current of the Mini-Fit Jr system — up to 9 A per circuit when using the matching crimp terminal (series 5556).
