Samtec 2x26 Connector Pin Length Question

I obtained the Samtec stackable 2x26 connectors (Samtec SSQ-126-22-G-D) you specified at However, the pins in the connector I received are shorter than those provided with the connector in the Protoboard Kit (711 - 00303). It doesn't appear to me that the pin length remaining after insertion into my PCB will make a reliable connection into the next connector. Can you help?

Please refer to page 17 of the Motherboard Rev E datasheet ( ... 0484-E.pdf) for an overview of the connectors used, and their applications.

The SSQ-126-22-G-D is a 10mm bus extension. You use it only in conjunction with modules that stack at an inter-board height of 24 or 25mm, not the usual 15.24mm (0.600").

The ESQ-126-37-G-D is found, for example, on the Motherboard and on the Dev Board.

The ESQ-126-39-G-D is found in the Protoboard Kit and on just about every CubeSat Kit-compatible module.

All can be sampled from Samtec.
