Key Features
- 10-position dual-row 0.050" (1.27 mm) pitch Tiger Eye terminal strip achieving twice the pin density of standard 0.100" connectors in a 0.375" body length for ultra-compact PCB layouts
- 15 µin gold-plated mating contacts on phosphor bronze base providing low contact resistance and reliable signal integrity across hundreds of mating cycles
- Cost-effective Tiger Eye series design offering SAMTEC's proven 0.050" grid interconnect performance at a lower price point than premium micro-pitch alternatives
- Matte tin solder termination tails compatible with standard PCB wave and selective soldering processes, simplifying board assembly without specialized tooling
Applications
The TFC-105-02-LM-D-A is used in compact embedded computing modules, FPGA daughter cards, and high-density PCB-to-cable assemblies where a 0.050" pitch 10-pin dual-row interface reduces connector footprint by 50% compared to 0.100" alternatives. Its gold-plated contacts ensure reliable signal transmission in high-cycle test sockets and development board expansion headers. The Tiger Eye series cost-effective positioning makes it suitable for volume production in consumer electronics, medical monitoring devices, and telecom line cards where fine-pitch board connectivity is required at competitive bill-of-materials cost.

Frequently Asked Questions
What is the contact pitch and pin configuration of the TFC-105-02-LM-D-A?
The TFC-105-02-LM-D-A has 10 positions arranged in a dual-row layout on a 0.050" (1.27 mm) pitch. The body measures 0.375 inches in length and 0.226 inches in depth, making it significantly more compact than standard 0.100" pitch 10-pin connectors while maintaining the same phosphor bronze contact material and gold mating finish.
How does the 15 µin gold contact finish on TFC-105-02-LM-D-A affect connector longevity?
The 15 µin (microinch) gold plating on the phosphor bronze mating contacts provides low and stable contact resistance typically below 30 milliohms through hundreds of mating cycles. Gold resists oxidation and surface tarnishing, making this connector suitable for test fixture sockets and development board headers that experience frequent connector insertions over the product lifetime.
When should a designer choose TFC-105-02-LM-D-A over a standard 0.100" pitch 10-pin connector?
A designer should choose the TFC-105-02-LM-D-A when PCB area for the connector footprint is limited and a 0.100" pitch header would exceed space constraints. The 0.050" pitch reduces the connector body length from approximately 0.55 inches to 0.375 inches for a 10-position dual-row strip, freeing space on dense PCB assemblies in handheld instruments, IoT nodes, and compact single-board computers.
What mating cable assemblies are compatible with the TFC-105-02-LM-D-A terminal strip?
The TFC-105-02-LM-D-A mates with SAMTEC's 0.050" pitch female socket assemblies and compatible third-party crimp housings designed for 1.27 mm pitch dual-row connectors. Flat flexible cables (FFC) and micro ribbon cable assemblies in 10-conductor, 0.050" pitch configurations are common mating choices, and SAMTEC's FFSD or TFM female socket series are direct counterparts in the Tiger Eye family.
