CPAT-081-M-T-15EF

Overview

The CPAT-081-M-T-15EF is a high-density edge card connector manufactured by Samtec Inc. It belongs to the CPAT series, designed for side-card insertion applications in data communication and industrial systems. The component features a 0.60 mm pitch with 81 positions arranged in a triple row configuration (T). It utilizes Edge Rate® contacts optimized for signal integrity, supporting high-speed data transmission rates up to 64 Gbps PAM4 or 32 Gbps NRZ. The connector complies with SFF-TA-1002 specifications and supports PCIe 6.0 and CXL 3.2 standards. The suffix EF indicates specific termination and housing characteristics.

• Supports high-speed data rates up to 64 Gbps PAM4
• Compliant with SFF-TA-1002 specification for side-card applications
• Enables PCIe 6.0 and CXL 3.2 capability

Applications

• Data communication systems requiring high bandwidth
• Industrial control systems with high-density interconnect needs
• PCI Express 6.0 compliant hardware platforms
• Compute Express Link (CXL) 3.2 enabled architectures

Procurement Notes

Verify the exact part number against official Samtec documentation to ensure correct pitch, row count, and termination style. Confirm that the Edge Rate® contact type matches your signal integrity requirements. Check for RoHS compliance status and material declarations relevant to your manufacturing region. Ensure mating components are compatible with the 0.60 mm pitch and specified stack-up height.

Selection Notes

Select this connector when designing for high-speed side-card interfaces requiring 0.60 mm spacing. Consider the triple-row layout for increased I/O density within constrained board areas. Evaluate the need for SFF-TA-1002 compliance if interfacing with standard server blades. Assess thermal and mechanical constraints associated with high-frequency signal transmission at these densities.

Part Context

This component is part of Samtec's Generate® line of high-speed interconnect solutions. The CPAT series specifically targets side-card applications where space efficiency and signal performance are critical. It complements other Samtec offerings like GC6 cable assemblies and various cage options for transceiver integration.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific configuration. Cross-referencing requires matching the 0.60 mm pitch, 81-position count, triple-row arrangement, and Edge Rate® contact technology. Verify compatibility with existing PCB footprints and mating connectors before substitution.
