What are the key features of TFC-147-02-FM-D-K-TR?
- 94 positions in a compact 0.050 inch (1.27 mm) pitch dual-row layout providing high-density interconnection in minimal PCB real estate
- Tiger Eye contact design offering reliable low-insertion-force mating with consistent 30 µin gold plating for long contact life
- Tape-and-reel (TR) packaging enabling automated SMT pick-and-place assembly at high production volumes
- Cost-effective terminal strip design reducing BOM cost compared to precision machined contact alternatives without sacrificing signal integrity
What is TFC-147-02-FM-D-K-TR used for?
The TFC-147-02-FM-D-K-TR is used in high-density board-to-board and mezzanine card interconnects where 94 signals must cross a card edge within a 1.27 mm pitch footprint. Its tape-and-reel format suits automated SMT assembly lines producing networking, storage, and computing module backplanes at volume. The fine-pitch dual-row configuration also suits FPGA daughter card and DSP module interfaces where pin count density exceeds what standard 2.54 mm pitch connectors can provide.

Frequently Asked Questions
How many signals can the TFC-147-02-FM-D-K-TR carry and what pitch spacing does it use?
The TFC-147-02-FM-D-K-TR provides 94 positions arranged in a dual-row layout on a 0.050 inch (1.27 mm) pitch. This pitch is half the standard 0.100 inch spacing, allowing the connector to fit 94 signals into the same board length as a 47-position standard-pitch connector, making it valuable in space-constrained FPGA and processor module designs.
Is the TFC-147-02-FM-D-K-TR compatible with automated SMT assembly lines and what packaging format does it ship in?
Yes. The -TR suffix denotes tape-and-reel packaging, which is fully compatible with standard SMT pick-and-place equipment using 12 mm to 16 mm carrier tape. This enables automated high-volume placement at rates exceeding 5000 components per hour on modern assembly lines, reducing handling costs compared to loose-piece or tray packaging used for lower-volume orders.
What is the contact gold plating thickness on the TFC-147-02-FM-D-K-TR and how does it affect connector lifespan?
SAMTEC Tiger Eye series connectors are typically plated with 30 µin (0.76 µm) of gold over nickel on the contact surfaces. This plating thickness provides a minimum of 100 mating cycles reliability under normal conditions, and the Tiger Eye wiping action removes surface contamination on each insertion, maintaining contact resistance below 50 mΩ throughout the rated service life.
For a compact FPGA mezzanine design, how does the TFC-147-02-FM-D-K-TR reduce board space compared to a 0.100 inch pitch alternative?
A 0.100 inch pitch dual-row connector carrying 94 signals would span approximately 47 positions × 2.54 mm = 119 mm in length. The TFC-147-02-FM-D-K-TR at 0.050 inch pitch spans only about 60 mm for the same 94 positions, saving nearly 50% of connector row length — freeing significant PCB area for routing layers, decoupling capacitors, or additional I/O in a compact mezzanine card form factor.
