Hello,
Im designing a sensor's platform based on a stacked design, so I have two boards which I have to connect trough a board-to-board connector.
I already spent dozens of hours trying to select the most appropriate connector but Im still not sure.
Some specs Im looking for:
- small (about 1cm on the wider side)
- should provide a solid connection (a "click" sound)
- 15~20 pins, 2 rows
- stack height = 5~6mm
- polarized
My first choice was this (from FCI):
20021221-00012C4LF
20021321-00012C4LF
But they have only 12pin (pitch=1,27mm) and don't provide a solid connection.
Then I tried some Hirose DF9 series but the stack height is < 5mm.
Now Im using FCI Conan series (pitch = 1mm, 15pins):
91910-21415LF
91930-21115LF
These fit really well, but now Im worried about their availability.
Im in Europe so my prefered distributors are Mouser and Farnell. But just Mouser keeps stock of these connectors and the current stock is ~500 or less. So, I guess if I want to make >250 boards I will get a problem, taking into account that each board has 2 connectors.
So, I would like to ask you two questions:
1 ) Based on the specs above, could you suggest me a good board to board connector? (which has good availability)
2 ) What is the common practice on buying and maintaining connectors stock (from a commercial standpoint)? I guess relying on distributors is not safe.
Thanks in advance for your help!
