Key Features
- 28-position dual-row male terminal strip with 0.050" (1.27 mm) pitch and 3 µin gold mating contacts on phosphor bronze for reliable low-resistance connections
- Peg (PEG) board mounting option for precise PCB alignment and improved soldering registration during assembly
- Tin (Sn) over nickel (Ni) barrier termination finish providing reliable solder joints compatible with lead-free assembly processes
Applications
The TFC-114-02-F-D-A-K is suited for 28-signal board-to-board interfaces in compact embedded controllers, industrial sensor modules, and telecommunications line cards requiring connectivity at 0.050" pitch. The peg-mounting feature ensures accurate connector placement during PCB assembly, reducing misalignment defects in high-volume manufacturing. Phosphor bronze contacts with 3 µin gold plating deliver consistent contact performance in commercial-grade applications across moderate duty cycles.

Frequently Asked Questions
What is the gold plating thickness on TFC-114-02-F-D-A-K mating contacts and how does it affect durability?
The TFC-114-02-F-D-A-K uses 3 µin (microinches) gold plating on phosphor bronze mating contacts. This thin gold flash provides adequate corrosion protection and low contact resistance for low-to-moderate mating cycle applications. At 28 positions and 0.050" (1.27 mm) pitch, it is a cost-efficient choice for commercial electronics where extended-life 15 µin or 30 µin gold is not required.
How does the peg mounting option on TFC-114-02-F-D-A-K help during PCB assembly?
The PEG board mounting option consists of plastic alignment pegs that insert into corresponding holes in the PCB, holding the 28-position connector body in place before and during soldering. This prevents the 0.050" pitch dual-row connector from shifting during wave or hand soldering, reducing solder bridges and misalignment defects, and improving first-pass assembly yield in production environments.
How does the TFC-114-02-F-D-A-K differ from TFC-114-02-L-D-A in contact finish?
The TFC-114-02-F-D-A-K uses a thinner 3 µin gold flash on its mating contacts, while TFC-114-02-L-D-A carries 15 µin gold plating. Both share the same 28-position dual-row layout at 0.050" (1.27 mm) pitch with phosphor bronze contacts, but the -F variant is better suited for cost-sensitive designs with limited mating cycles, whereas the -L variant is preferred for applications requiring extended contact life and lower resistance over many insertions.
