Key Features
- 76-position dual-row layout at 0.050 inch (1.27 mm) pitch provides very high signal density for FPGA and DSP module interconnect designs
- LM (low-profile mounting) style minimizes stack height above the PCB surface, enabling ultra-compact multi-board assembly configurations
- Keying (K option) ensures correct connector orientation during mating of the 76-pin interface, reducing risk of mis-connection in automated assembly
Applications
The SAMTEC TFC-138-02-LM-D-A-K is suited for FPGA mezzanine card interfaces, high-pin-count backplane assemblies, and multi-board embedded computing systems that require 76 signal lines at 0.050 inch pitch in a low-profile form factor. Telecommunications infrastructure boards and high-channel-count data acquisition instruments also benefit from its dual-row keyed terminal strip design.

Frequently Asked Questions
How many positions does the TFC-138-02-LM-D-A-K support in each row?
The TFC-138-02-LM-D-A-K features 76 positions total in a dual-row configuration, providing 38 contacts per row at 0.050 inch (1.27 mm) pitch, making it one of the highest-density Tiger Eye terminal strips available for module-to-board and backplane signal interconnect designs.
What does the LM suffix specify for the TFC-138-02-LM-D-A-K, and how does it benefit board-level packaging?
The LM suffix on the TFC-138-02-LM-D-A-K designates a low-profile mounting style that reduces the connector's standoff height above the PCB, allowing tighter board-to-board stack spacing of less than standard stacking heights, which is critical in compact 76-pin dual-row multi-board assemblies used in industrial and telecom modules.
When should the TFC-138-02-LM-D-A-K be chosen over lower-position-count Tiger Eye connectors like TFC-134?
The TFC-138-02-LM-D-A-K with 76 positions is preferred over 68-position alternatives when the design requires 8 additional signal or power lines in a single 0.050 inch pitch connector, such as in high-channel ADC boards, parallel data buses, or FPGA I/O expansion cards where routing all signals through a single 76-pin connector reduces connector count and PCB complexity.
