What are the key features of TFC-102-02-F-D?
- 4-position dual-row board connector at 0.050" (1.27 mm) pitch delivers the smallest Tiger Eye footprint for simple SPI, I2C, or power interface routing between stacked PCBs
- Tin with nickel barrier termination finish ensures robust solder joint integrity through standard reflow profiles up to 260°C
- Tiger Eye cost-effective construction provides SAMTEC-quality dimensional accuracy at reduced component cost for high-volume low-pin-count interconnect requirements
What is TFC-102-02-F-D used for?
The TFC-102-02-F-D is suited for minimal pin-count board-to-board connections such as simple power plus data interfaces, SPI slave selects, or interrupt lines between a main PCB and a small sensor or display sub-module. Its 4-position dual-row layout at 0.050" pitch keeps the connector footprint under 5 mm long, making it appropriate for ultra-compact IoT nodes, wearable devices, and miniaturised industrial sensors. The cost-effective Tiger Eye design reduces BOM cost in high-volume production.

Frequently Asked Questions
With only 4 positions at 0.050" pitch, which simple bus interfaces can the TFC-102-02-F-D support between two stacked PCBs?
The 4-position TFC-102-02-F-D can carry a 2-wire I2C bus (SDA and SCL) plus one dedicated power and one ground pin, or a 3-wire SPI interface (MOSI, MISO, SCLK) with a ground reference pin. This makes it ideal for attaching small sensor breakout boards, EEPROM daughter cards, or RTC modules to a main PCB where only 3.3 V or 5 V logic signals at low current are exchanged.
How does the TFC-102-02-F-D's footprint size compare to a through-hole 4-pin 2.54 mm header in ultra-compact PCB designs?
The TFC-102-02-F-D occupies approximately 2.5 mm x 5.8 mm of PCB area at 0.050" (1.27 mm) pitch versus roughly 5 mm x 10 mm for a standard through-hole 4-pin 2.54 mm dual-row header, representing a footprint reduction of over 70%. This space saving is significant in wearable sensor nodes and credit-card-sized embedded modules where every square millimetre of PCB area is at a premium.
What is the termination finish of the TFC-102-02-F-D's contacts, and why does the nickel barrier matter for soldering reliability?
The TFC-102-02-F-D uses tin (Sn) termination with a nickel (Ni) barrier layer beneath. The nickel barrier prevents tin diffusion into the phosphor bronze contact base material, which would otherwise form intermetallic compounds over time and degrade solder joint pull strength. This bilayer finish maintains reliable electrical contact through thermal cycling between -40°C and +105°C in harsh industrial and automotive-adjacent applications.
