Key Features
- 4-position dual-row configuration at 0.050 inch (1.27 mm) pitch in a minimal PCB footprint for compact connector applications
- Tape and reel (TR) packaging enables automated pick-and-place SMT assembly at high production volumes
- Keying option (-K) provides polarized mating to prevent incorrect connector insertion in densely packed PCB assemblies
- Tiger Eye cost-effective design delivers reliable commercial-grade connectivity at reduced cost for low-pin-count interface applications
Applications
The TFC-102-02-FM-D-A-K-TR is suited for low-pin-count board connector applications in consumer electronics, IoT devices, and sensor modules that require compact 4-pin signal or power connections at 0.050 inch pitch. Its surface mount termination and tape and reel packaging make it ideal for high-volume automated PCB assembly lines using standard SMT reflow processes. The keying feature and small form factor support reliable polarized mating in densely populated PCB designs with limited connector clearance.

Frequently Asked Questions
How many positions does the TFC-102-02-FM-D-A-K-TR have and how compact is its PCB footprint at 0.050 inch pitch?
The TFC-102-02-FM-D-A-K-TR has 4 positions in a dual-row layout with 2 pins per row at 0.050 inch (1.27 mm) pitch. This results in an extremely compact PCB footprint, with a row spacing and body size typical of Samtec TFC series connectors, making it ideal for space-constrained IoT and sensor PCB designs.
What assembly method does the TFC-102-02-FM-D-A-K-TR support and how does the packaging format facilitate production?
The TFC-102-02-FM-D-A-K-TR uses surface mount (FM) termination and is supplied in tape and reel (TR) packaging, fully compatible with automated SMT pick-and-place equipment. This enables high-speed reflow soldering at standard lead-free profiles around 260°C, supporting large-scale production volumes without manual connector placement.
Why is the keying option important on a 4-pin connector like the TFC-102-02-FM-D-A-K-TR?
Even with only 4 pins, incorrect mating orientation can cause circuit damage by reversing power and signal connections. The -K keying option on the TFC-102-02-FM-D-A-K-TR provides a physical polarization feature that allows insertion in only one correct direction, protecting sensitive circuits and reducing rework costs in both assembly and field maintenance situations.
For which low-pin-count interface applications is the TFC-102-02-FM-D-A-K-TR most cost-effective?
The TFC-102-02-FM-D-A-K-TR is most cost-effective in applications needing a small 4-pin polarized connector such as I2C interfaces (2-wire with power and ground), UART debug headers, or simple analog sensor connections where a 0.050 inch pitch surface mount connector minimizes PCB area. The Tiger Eye design keeps per-unit cost low for high-volume commercial production runs.
