Frequently Asked Questions
How does the 0.050 inch pitch of SEAM-50-11.0-S-08-2-A-K-TR enable higher signal density than standard 0.100 inch connectors?
At 0.050 inch (1.27 mm) pitch, SEAM-50-11.0-S-08-2-A-K-TR achieves twice the contact density of a 0.100 inch pitch connector in the same PCB footprint. This allows engineers to route high-speed differential pairs, power contacts, and grounds across a compact array in applications like FPGA mezzanine cards and data-center switching fabrics that operate at 10 Gbps or higher.
Why is 30 µin gold plating on the mating contacts of SEAM-50-11.0-S-08-2-A-K-TR specified rather than a thinner 10 µin finish?
The 30 µin (microinch) gold-over-nickel finish on the mating contacts provides extended wear resistance compared to 10 µin gold, supporting more mating cycles before contact resistance degrades. This thicker gold layer is standard practice for high-reliability board-stacking connectors used in test equipment and telecom line cards where periodic re-mating during field maintenance is expected.
For a mezzanine card carrying tall SMD inductors, does the 11.0 mm stack height of SEAM-50-11.0-S-08-2-A-K-TR provide sufficient clearance?
Yes, the 11.0 mm stack height of SEAM-50-11.0-S-08-2-A-K-TR creates an inter-board gap of 11 mm when mated. This clearance is sufficient for most SMD components, including inductors up to approximately 8 mm to 10 mm tall, depending on body dimensions and the PCB thicknesses of both the mezzanine and carrier boards.
What is the factory lead time for SEAM-50-11.0-S-08-2-A-K-TR, and how does the open-pin-field design affect ordering strategy?
Samtec lists a factory lead time of 1 week for SEAM-50-11.0-S-08-2-A-K-TR. The open-pin-field format means the 50-position-per-row array allows engineers to define custom signal, ground, and power pin assignments without ordering a new part number, simplifying procurement and inventory planning for platform variants that share the same mechanical footprint.
