Key Features
- Gold (AU) over nickel (NI) contact finish on mating interface achieving 15mΩ or lower contact resistance for reliable low-loss signal and power connections
- Phosphor bronze contact material providing excellent spring-back resilience and consistent normal force across hundreds of mating cycles
- Compact dual-row male board stacking connector with 0.625 inch body length enabling tight PCB-to-PCB stacking in space-constrained assemblies
Applications
The TFC-105-02-F-D-A is designed for compact board-to-board stacking applications in portable instruments, wearable electronics, and industrial sensor modules where a 10-position dual-row male connector establishes reliable signal and power interconnects. Its gold over nickel contact finish with 15mΩ contact resistance ensures minimal signal loss in RF-adjacent, data, and mixed-signal designs across multiple mating cycles. The connector is commonly used in modular embedded computing stacks, handheld test equipment add-on boards, and compact medical device sub-assemblies requiring a small board stacking footprint.

Frequently Asked Questions
What is the contact resistance specification of the TFC-105-02-F-D-A and why does it matter for signal paths?
The TFC-105-02-F-D-A specifies a maximum contact resistance of 15mΩ per contact with gold (AU) over nickel (NI) plating on the mating interface. Low contact resistance minimizes voltage drop and signal degradation, which is critical for high-speed digital signals and sensitive analog measurement paths, where a resistance much above 50mΩ can degrade signal integrity and introduce thermal losses in high-current power pins.
How many positions does the TFC-105-02-F-D-A have and what is the body length?
The TFC-105-02-F-D-A has 10 total positions in a dual-row (2x5) layout with a body length of 0.625 inch and body breadth of 0.225 inch. This compact rectangular footprint makes it one of the smaller board stacking connectors in the Samtec TFC series, suitable for stacking mini PCBs in portable and wearable electronic designs where every millimeter of board space counts.
Which board stacking and modular system designs benefit from the TFC-105-02-F-D-A male connector?
Modular sensor nodes, compact datalogger boards, wearable health monitoring devices, and small industrial wireless modules benefit from the TFC-105-02-F-D-A dual-row male stacking connector. In a typical 2-board stack, this 10-position connector carries up to 8 signal lines plus 2 power pins between a main CPU board and a plug-in radio or sensor daughter card, establishing all interconnects in a footprint under 16mm by 6mm.
What contact material and mating finish does TFC-105-02-F-D-A use, and how does this affect procurement lifetime planning?
Contacts are made from phosphor bronze with gold (AU) over nickel (NI) mating finish and tin over nickel (Sn/Ni) termination finish. Phosphor bronze provides 40% to 60% higher spring fatigue life than brass, and the gold mating finish maintains stable contact resistance across at least 200 insertion cycles. With a YTEOL of 8 years, this connector is suitable for long-lifecycle industrial and medical equipment that undergoes periodic maintenance and module replacement.
