Key Features
- 54-position dual-row terminal strip at 0.050" (1.27 mm) pitch enabling dense signal connections between mating boards in compact PCB assemblies
- Tiger Eye contact technology with bifurcated wiping action ensuring reliable low-resistance connections across many mating cycles
- Cost-effective design targeting volume production while maintaining SAMTEC's quality standards for signal integrity
Applications
The TFC-127-02-F-D-A-K is deployed in mezzanine card, daughter board, and module interconnect applications requiring 54 dual-row contacts at 0.050" pitch in a cost-optimized package. Data communication equipment, industrial programmable logic controllers, and embedded computing boards benefit from its combination of signal density and competitive pricing. This terminal strip is particularly well suited for volume production designs where connector cost per pin is a significant factor in system BOM.

Frequently Asked Questions
How many positions does the TFC-127-02-F-D-A-K have, and what pitch does it use?
The TFC-127-02-F-D-A-K offers 54 positions in a dual-row layout at 0.050" (1.27 mm) pitch. This allows routing of 54 simultaneous signal or power lines across mating boards in a footprint significantly smaller than 0.100" pitch alternatives, making it suitable for space-critical mezzanine and daughter card PCB designs in telecom and embedded applications.
What is the Tiger Eye contact technology, and how does it improve connection reliability in the TFC-127-02-F-D-A-K?
Tiger Eye contacts feature a bifurcated spring beam design that creates a wiping motion during connector insertion, displacing surface oxides and debris from the contact area. This self-cleaning action maintains low, stable contact resistance across repeated mating cycles, which is important for 54-position signal connectors in test equipment, industrial controls, and communication boards subject to field replacement.
For which cost-sensitive production programs is the TFC-127-02-F-D-A-K most appropriate?
The TFC-127-02-F-D-A-K is targeted at cost-sensitive, medium-to-high volume programs such as consumer electronics modules, network interface cards, and industrial sensor boards where 54 contacts at 0.050" pitch are required but premium pricing is not justified. Its competitive unit cost reduces the connector line item in high-volume BOM structures without sacrificing essential electrical and mechanical performance.
What mating connector types are compatible with the SAMTEC TFC-127-02-F-D-A-K?
The TFC-127-02-F-D-A-K mates with SAMTEC's 0.050" pitch dual-row socket strips and receptacle connectors from the SFM or SFS series, forming a complete board-to-board interconnect pair. Board stack height can be adjusted by selecting socket strips with different body heights, typically ranging from approximately 3.5 mm to 11 mm, to match PCB spacing requirements in mezzanine assembly designs.
