Frequently Asked Questions
Which mezzanine layouts benefit from the 0.4 mm contact pitch?
The fine 0.4 mm pitch and 40-pin arrangement support dense board-to-board signal routing where enclosure width and PCB area are tightly constrained.
How should engineers plan the board stack around this receptacle?
This receptacle provides a 4.0 mm stacking height and 40 pins, so mating-board spacing, component keep-outs, and insertion alignment should be verified together.
For volume purchasing, what sourcing factors deserve attention?
The data lists a 12-week factory lead time for this 40-pin connector, making approved-source checks, demand forecasts, and safety-stock planning important before release.
