• Features a 0.635 mm pitch slim form factor design
• Incorporates an 'anti-polarity' pin option to reduce far-end crosstalk

Applications

• High-performance computing interconnects
• Data center server backplanes
• Storage area network infrastructure
• Telecommunications base stations

Procurement Notes

Verify the specific cable length and termination style against project requirements before ordering. Confirm that the selected variant matches the required I/O count and differential pair configuration. Ensure compatibility with mating receptacles within the same HDR series family. Check for RoHS3 compliance status if environmental regulations apply to your assembly process.

Selection Notes

Select this model when high-density board-to-board or cable-to-board connections are required at speeds up to 32 Gbps NRZ. Consider the slim profile for space-constrained designs. Evaluate the need for anti-polarity options to simplify assembly and prevent misalignment errors during mating cycles.

Part Context

This part is part of Samtec's AcceleRate® ARC6 line, which focuses on slim, high-density connectivity solutions. It complements other HDR series components by offering specialized cable assemblies optimized for signal integrity in next-generation computing architectures.

Replacement Considerations
