Key Features
- 30 µin gold-plated mating contacts ensure low and stable contact resistance over 1000+ mating cycles in card edge applications
- Polarized dual-row plug housing with 16 positions (8 per row) prevents incorrect insertion in mixed-signal backplane designs
- Compact 0.494 x 0.275 inch body fits tight board-to-board spacing in embedded computing and industrial control modules
Applications
The MEC1-108-02-S-D-A is used in card edge backplane assemblies, daughter-card interconnects, and industrial PCIe-style expansion slots where a polarized dual-row plug with gold-plated contacts is required for long-term reliability. Its compact 0.494 inch body length suits space-constrained embedded computing modules such as COM Express and custom SBC designs. The 30 µin gold contact finish makes it appropriate for medical instrumentation and test equipment that require low contact resistance over thousands of mate/demate cycles.

Frequently Asked Questions
How many positions and rows does the MEC1-108-02-S-D-A provide, and what contact finish does it use?
The MEC1-108-02-S-D-A is a dual-row card edge connector with 8 positions per row (16 total circuits) and uses 30 µin (0.76 µm) gold plating on mating contacts, ensuring stable contact resistance below 20 mΩ over more than 1000 mate/demate cycles.
Why is the polarized housing of MEC1-108-02-S-D-A important in backplane designs with mixed voltage levels?
The polarized plug body mechanically keys the connector so it can only mate in one orientation, eliminating reverse-insertion errors in backplanes where adjacent slots carry different voltages such as 3.3 V, 5 V, and 12 V rails within 10 mm of each other.
What body dimensions does MEC1-108-02-S-D-A have and how do they affect board-stacking height?
The MEC1-108-02-S-D-A body measures 0.494 inch (12.55 mm) long, 0.275 inch (6.98 mm) wide, and 0.356 inch (9.04 mm) deep, setting the minimum board-to-board stacking height in a mated assembly to approximately 9 mm before accounting for the mating receptacle depth.
What lead time is typical for MEC1-108-02-S-D-A and how does this compare with longer-lead SAMTEC variants?
SAMTEC lists MEC1-108-02-S-D-A with a 1-week factory lead time, which is significantly shorter than the 6 to 13 week lead times common for custom or lower-volume SAMTEC connector variants, making it a practical choice for rapid prototyping and small-batch production runs needing quick turnaround.
