Key Features
- 8 positions on a 0.050 inch (1.27 mm) dual-row pitch enabling compact board-to-board connections in a minimal PCB footprint
- Fine-mating (-FM) contact design providing reliable engagement and consistent contact resistance below 20 mΩ over multiple mating cycles
- Gold-plated mating surfaces on phosphor bronze contacts resisting oxidation and maintaining signal integrity in industrial and automotive environments
- Cost-effective terminal strip design offering reliable 8-channel interconnection at lower cost than precision circular or ZIF connector alternatives
Applications
The TFC-104-02-FM-D-A is suited for compact 8-signal board-to-board interfaces in embedded MCU modules, IoT sensor nodes, and industrial instrument daughter cards where fine 1.27 mm pitch saves PCB area compared to standard 2.54 mm headers. Its gold-plated contacts ensure reliable connections for analog sensor signals, SPI buses, and low-voltage digital I/O crossing from a main carrier board to a small plug-in module. The SMT dual-row footprint integrates seamlessly with automated reflow assembly processes for consumer electronics and industrial product manufacturing.

Frequently Asked Questions
How many signals does the TFC-104-02-FM-D-A support and what is its pitch compared to standard 0.100 inch headers?
The TFC-104-02-FM-D-A supports 8 signal positions in a dual-row layout at 0.050 inch (1.27 mm) pitch, which is exactly half the 0.100 inch (2.54 mm) pitch of standard pin headers. This halved pitch allows 8 contacts to fit in the same PCB length as a 4-position standard header, effectively doubling signal density and making it the preferred choice for compact IoT and embedded module interconnects where board space is limited.
For an 8-channel SPI interface on a sensor module, what is the advantage of fine-mating contacts on the TFC-104-02-FM-D-A?
The fine-mating (-FM) contact design uses a narrower, precisely formed tip that achieves consistent contact with the mating receptacle even after repeated insertions. On an 8-channel SPI bus operating at 10 MHz to 50 MHz, contact resistance below 20 mΩ per pin keeps signal integrity high, adding less than 0.2 mV of resistive drop at 10 mA current levels and avoiding reflections from loose or worn contact interfaces.
How does the TFC-104-02-FM-D-A footprint size compare to a DIP-8 socket for a compact sensor module design?
A standard DIP-8 socket occupies approximately 10.2 mm × 7.6 mm = 77.5 mm² of PCB area with 2.54 mm row spacing. The TFC-104-02-FM-D-A dual-row 1.27 mm pitch footprint for 8 positions measures approximately 5.1 mm × 3.8 mm = 19.4 mm², reducing the connector footprint by 75% — freeing significant PCB area on a small sensor module card measuring 20 mm × 30 mm or less.
In what production environments does the TFC-104-02-FM-D-A offer procurement advantages over custom or proprietary board-to-board connectors?
SAMTEC's Tiger Eye series is a catalog standard product with global distribution and typically 2 to 4 week lead times, whereas custom or proprietary board-to-board connectors often require 12 to 24 week tooling lead times and minimum order quantities of 10,000 pieces. For production runs of 500 to 5000 units per month, the TFC-104-02-FM-D-A eliminates tooling cost (often $5,000 to $20,000) and supply-chain risk, making it the cost-effective choice for industrial instrumentation and embedded computing products.
