Key Features
- 58-position dual-row Tiger Eye terminal strip at 0.050" (1.27 mm) pitch for ultra-high-density signal interconnects in compact PCB designs
- Cost-effective Tiger Eye contact design delivers reliable 1.27 mm pitch mating performance at a competitive price point versus standard fine-pitch connectors
- Dual-row (D) configuration halves the linear board space requirement compared to equivalent single-row 0.050" pitch connectors across 58 positions
- Female-mate (FM) contact style accepts standard 0.050" pitch male terminal strips for flexible board-to-board and cable-to-board assembly configurations
Applications
The TFC-129-02-FM-D-A is suited for high-density board-to-board and mezzanine card interconnects in compact embedded systems, portable medical instruments, and telecommunications line cards where 58 signals must be routed through a 1.27 mm pitch dual-row interface. The Tiger Eye cost-effective design reduces BOM cost for high-volume consumer electronics and industrial IoT modules requiring fine-pitch connectivity without premium connector pricing. Its 0.050" pitch makes it compatible with Samtec's broad TFC and TFM series mating ecosystem for flexible system architecture.

Frequently Asked Questions
What pitch and position count does the TFC-129-02-FM-D-A offer, and how does this compare to standard 0.100" pitch connectors?
The TFC-129-02-FM-D-A uses a 0.050" (1.27 mm) pitch with 58 positions in a dual-row layout. Compared to a 0.100" (2.54 mm) pitch connector with the same 58 positions, this fine pitch reduces the connector body length by approximately 50%, making it a critical space-saving option for compact PCBs with board area budgets under 40 mm for the connector footprint.
What does the Tiger Eye contact design in TFC-129-02-FM-D-A provide in terms of cost and reliability for high-volume designs?
The Tiger Eye contact geometry is Samtec's cost-optimized dual-beam contact design that maintains reliable mating force and contact resistance below 30 mΩ across 58 positions while reducing material usage compared to traditional full-form contacts. This makes the TFC-129-02-FM-D-A approximately 20% to 30% lower in unit cost than equivalent precision machined 0.050" pitch connectors, benefiting high-volume production runs in consumer electronics and industrial IoT applications.
Which mating connectors are compatible with the TFC-129-02-FM-D-A for board-to-board assembly?
The TFC-129-02-FM-D-A female-mate (FM) dual-row contacts are designed to mate with Samtec's TFC series male terminal strips and TFM series male connectors on the same 0.050" (1.27 mm) pitch. Mating engagement requires approximately 0.1N to 0.3N per contact for the 58-position dual-row configuration, with a typical stack height ranging from 3 mm to 15 mm depending on the selected male connector tail length.
For a portable medical device with board height constraints under 5 mm, how suitable is the TFC-129-02-FM-D-A?
The TFC-129-02-FM-D-A is well suited for ultra-compact medical device boards where a 58-signal interface must fit within a 5 mm stack height. The 0.050" (1.27 mm) pitch dual-row layout minimizes the PCB real estate to approximately 37 mm for 29 positions per row, and the Tiger Eye contact depth allows mated heights as low as 3 mm to 4 mm when paired with corresponding low-profile male connectors from the TFM family.
