Applications
The TFC-103-02-F-D-A is used in compact daughter card and module interface applications where 6 low-resistance signal connections are required within a 1.27 mm pitch footprint. Its phosphor bronze gold-plated contacts and 15 mΩ resistance make it suitable for analog signal routing and low-voltage digital interfaces between main boards and small sensor or communication modules. The surface-mount footprint integrates easily into standard reflow assembly processes for IoT devices, medical instruments, and industrial sensor nodes.

Frequently Asked Questions
What is the contact resistance of the TFC-103-02-F-D-A and why does it matter for low-voltage signal interfaces?
The TFC-103-02-F-D-A specifies a maximum contact resistance of 15 mΩ per contact. On a 1.8 V logic interface carrying 20 mA, the voltage drop across one contact is only 0.3 mV — negligible compared to a 180 mV noise margin. This low resistance also means less than 6 µW of power dissipation per contact, keeping thermal rise below 1 °C even in dense SMD board-to-board assemblies.
How much board space does the TFC-103-02-F-D-A occupy and how does it compare to a 6-pin 2.54 mm pitch header?
The TFC-103-02-F-D-A measures 0.425 inch × 0.225 inch (10.8 mm × 5.7 mm), occupying approximately 62 mm² of PCB area. A standard 6-position 2.54 mm pitch single-row header occupies about 15 mm × 8 mm = 120 mm². The TFC-103 saves nearly 50% of footprint area while providing a dual-row layout, making it ideal for small-form-factor modules where PCB real estate is at a premium.
What contact material and plating does the TFC-103-02-F-D-A use and how does this affect mating cycle reliability?
Contacts are phosphor bronze with gold over nickel mating finish and tin-with-nickel-barrier termination plating. The gold mating surface maintains contact resistance below 15 mΩ for a minimum of 100 mating cycles per SAMTEC specification, while the nickel barrier layer under tin on the solder tails prevents tin whisker growth and preserves solderability after 12 months of shelf storage at standard conditions.
In which compact module designs is a 6-pin 1.27 mm pitch connector like the TFC-103-02-F-D-A typically preferred over wireless interconnect?
Wired connectors such as the TFC-103-02-F-D-A are preferred in designs where signal latency below 1 µs and DC or very low-frequency analog connectivity are required — tasks that wireless cannot perform. Examples include sensor module interfaces on medical ECG patches, direct ADC input routing on industrial process controllers, and SPI bus extensions between a main MCU board and a plug-in 6-channel sensor card in a sealed enclosure.
