Frequently asked questions
What does the 91618-310 mate with?
It mates with a standard 0.100-inch pitch dual-row pin header, 20 positions — any header with matching pitch, circuit count, and push-pull compatible geometry will pair with the Dubox receptacle.
What's the contact finish on the 91618-310 and why does it matter?
Gold at 30.0 µin on the mating face and tin at 78.7 µin on the solder post — the gold thickness on the mating interface governs how many cycles the connector will survive; the tin post is there for solderability and is not rated for repeated engagement.
What is the stacking height of the 91618-310?
The mated stack height is 10.81 mm — this is the z-height budget from board surface to board surface when the header and receptacle are fully mated.
What series does the 91618-310 belong to?
The 91618-310 is part of the Molex Dubox board-to-board connector series — a dual-row 0.100-inch pitch family used in board-to-board stacking applications across automotive, industrial, and telecom.
