Key Features
- 90-position dual-row terminal strip at 0.050 inch (1.27 mm) pitch in a 2.375 inch body with peg board mounting for precise SMT alignment
- Phosphor bronze contacts with 15 micro-inch gold mating finish and matte tin termination provide reliable low-resistance interfaces over extended mating cycles
- Tiger Eye cost-effective design delivers SAMTEC-quality 0.050 inch pitch interconnect performance at a competitive price point for high-volume production
Applications
The TFC-145-02-L-D-A-K-TR is used in high-density mezzanine board-to-board interconnect designs for telecommunications equipment, industrial computing, and FPGA-based platforms that require 90 signal paths at a 0.050 inch pitch within a 2.375 inch connector body. Its tape-and-reel packaging and peg board mounting features support automated SMT assembly lines producing large volumes of daughter-card and module interconnect PCBAs.

Frequently Asked Questions
What contact material and plating does the TFC-145-02-L-D-A-K-TR use for its mating interface?
The TFC-145-02-L-D-A-K-TR uses phosphor bronze contacts with a 15 micro-inch gold mating finish, which provides low contact resistance and reliable corrosion protection over many mating cycles. The termination side uses matte tin plating, compatible with standard SMT reflow soldering temperatures on FR-4 PCBs.
How does the peg board mounting feature of the TFC-145-02-L-D-A-K-TR aid PCB assembly?
The peg board mounting option physically registers the TFC-145-02-L-D-A-K-TR to the PCB surface, preventing connector shift during SMT reflow soldering of its 90 positions across a 2.375 inch body. This mechanical stabilization ensures consistent solder joint quality on all contacts, reducing rework rates on long fine-pitch connectors during high-volume production.
When is the TFC-145-02-L-D-A-K-TR a cost-effective alternative to premium SAMTEC mezzanine connectors?
The Tiger Eye TFC series is positioned as a cost-effective alternative to SAMTEC's higher-grade SFM and SFW series when the application requires 0.050 inch pitch dual-row connectivity with 90 positions but does not demand the extended mating cycle ratings or advanced contact geometries of premium lines. For production programs where connector unit cost significantly affects bill-of-materials targets, the TFC-145-02-L-D-A-K-TR provides reliable 15 micro-inch gold contact performance at a lower price per position.
