- Phosphor bronze contact material with tin-nickel termination provides excellent spring force retention and reliable electrical performance across hundreds of mating cycles
- RoHS compliant lead-free construction with body length of 4.125 inch supports high-density multi-row stacking connector applications in industrial and telecom systems
Applications
The TFC-140-02-F-D-A is designed for board-to-board stacking applications in modular computing, telecommunications line cards, and industrial control backplanes requiring a shrouded dual-row connector at 0.050" pitch. Its Tiger Eye contact system and gold-flash-over-nickel finish make it ideal for systems that undergo repeated board insertion cycles in equipment maintenance workflows. Engineers specify it for FPGA mezzanine card interconnects and high-channel-count data acquisition modules where both mechanical retention and signal integrity are critical.

Frequently Asked Questions
What contact finish is used on the TFC-140-02-F-D-A and how does it affect mating reliability?
The TFC-140-02-F-D-A uses gold flash over 50 micro-inch nickel on its mating contacts, providing corrosion resistance and low contact resistance suitable for moderate-cycle mating applications. The nickel barrier layer beneath the gold flash prevents diffusion and maintains contact integrity across repeated insertions in 0.050" pitch dual-row board stacking configurations.
Why does the shrouded design of the TFC-140-02-F-D-A benefit board stacking installations?
The shrouded housing of the TFC-140-02-F-D-A guides mating connectors into proper alignment during board stacking, preventing pin damage across its 4.125-inch body length and dual-row contact array. This is especially valuable in blind-mate or field-replaceable board applications where visual alignment of all contact positions is difficult, reducing assembly errors in industrial and telecom equipment.
How does phosphor bronze contact material contribute to TFC-140-02-F-D-A's long-term performance?
Phosphor bronze contacts in the TFC-140-02-F-D-A offer a high elastic modulus and good spring-back characteristics, maintaining consistent normal force across the dual-row contact array even after many mating cycles or extended temperature exposure from -55°C to +125°C. This material choice resists stress relaxation better than brass, ensuring the Tiger Eye contact system retains its designed electrical performance over the product lifetime.
