Key Features
- 62-position dual-row layout on 0.050" (1.27mm) pitch provides 124 contacts for high-density mezzanine board stacking
- Long-mating (LM) contact design increases mating depth for improved retention and contact reliability in vibration-prone environments
- Peg (K) retention option mechanically anchors the connector body to the PCB before and during reflow soldering
Applications
The TFC-131-02-LM-D-A-K is suited for mezzanine and daughter-card designs in industrial control, embedded computing, and avionics where 62 signal and power positions must mate reliably across a 1.27mm-pitch board interface. The long-mating contact variant provides a deeper engagement depth compared to standard TFC connectors, making it preferable in systems subject to shock or vibration. The peg retention feature adds mechanical stability during automated assembly, reducing connector misalignment and solder-joint stress on high-density PCB layouts.

Frequently Asked Questions
What distinguishes the LM (long-mating) variant TFC-131-02-LM-D-A-K from the standard TFC-131-02 versions?
The LM suffix indicates a long-mating contact length, meaning the square pins extend further into the socket housing during mating than a standard-length TFC contact. This increased engagement depth—typically 0.10 to 0.15 inches more than a standard pin—improves contact normal force and wipe length, reducing the risk of intermittent connections in assemblies exposed to vibration, shock, or thermal cycling found in industrial and avionics environments.
With 62 positions on a 1.27mm pitch, how long is the TFC-131-02-LM-D-A-K body, and what does that mean for PCB layout?
A 62-position dual-row Samtec TFC connector on a 0.050-inch (1.27mm) pitch spans approximately 1.575 inches (40mm) along the row direction. PCB designers must reserve a keep-out zone approximately 5mm wide around the body for the mating header plus peg holes if the K retention option is used. This length fits within a standard 2-inch card-edge allocation common in compact mezzanine formats such as PC/104 or proprietary embedded computing modules.
In which procurement scenarios does the TFC-131-02-LM-D-A-K offer a cost advantage over similar 62-pin high-speed connectors?
The TFC-131-02-LM-D-A-K offers the lowest cost per pin when the mezzanine interface carries signals below 500 MHz—such as parallel buses, I2C, SPI, CAN, or power rails—where the impedance-controlled contacts of Samtec SEARAY or high-speed Z-PACK connectors would be over-specified. For prototype and low-volume orders, the Tiger Eye series is also available without reel minimums, while high-speed alternatives typically require larger minimum order quantities and longer lead times.
