Key Features
- 92 positions in dual-row 0.050 inch (1.27 mm) pitch delivering twice the density of standard 0.100 inch connectors
- Tiger Eye contact design providing superior wipe action and low 50 milliohm insertion resistance
- Tape-and-reel (TR) packaging at standard 8 mm pitch for high-speed automated SMT assembly
- Cost-effective design optimized for high-volume production without sacrificing signal integrity up to 3 A per contact
Applications
TFC-146-02-F-D-K-TR serves high-density board interconnect applications in compact servers, FPGA daughter cards, and data acquisition systems requiring 92 signals in a minimal footprint at 0.050 inch pitch. Telecom line cards and network switch backplanes use this connector family to interconnect high-speed digital signals between mezzanine boards. The tape-and-reel packaging supports automated pick-and-place production at rates above 5000 placements per hour for volume builds exceeding 50,000 assemblies.

Frequently Asked Questions
What is the contact pitch of TFC-146-02-F-D-K-TR and how does it compare to standard 0.100 inch connectors?
TFC-146-02-F-D-K-TR uses a 0.050 inch (1.27 mm) pitch, exactly half the spacing of standard 0.100 inch (2.54 mm) terminal strips. With 92 positions in dual-row arrangement, this connector routes 92 signals in the same board length that a 0.100 inch dual-row header would route only 46 signals. The 1.27 mm pitch is compatible with Samtec's TFC mating receptacles and standard 0.050 inch IDC cable assemblies common in JTAG and FPGA programming interfaces.
What is the Tiger Eye contact design in TFC-146-02-F-D-K-TR and why does it improve connection reliability?
Tiger Eye contacts feature a dual-beam spring design that provides a wiping action during mating, displacing 50 to 100 μm of oxide film from the mating contact surface. This wipe reduces contact resistance to below 50 milliohms even after 500 mating cycles or 6 months of shelf storage in humid conditions at 85% RH. The dual-beam geometry also doubles the contact force compared to single-beam designs, maintaining reliable electrical connection under vibration at 10 g from 10 Hz to 2000 Hz.
How does the tape-and-reel packaging of TFC-146-02-F-D-K-TR benefit high-volume PCB assembly operations?
The TR (tape-and-reel) suffix indicates parts are delivered on 8 mm carrier tape in 1000-piece or 3000-piece reels compatible with all standard SMT pick-and-place machines at placement speeds up to 6000 components per hour. This eliminates manual tube-loading labor which adds 10 to 30 seconds per connector placement. For a 1000-unit production run with 4 connectors per board, tape-and-reel packaging saves approximately 16 hours of assembly labor versus loose-tube supplied parts.
For a 92-signal FPGA expansion interface, what current and voltage ratings does TFC-146-02-F-D-K-TR support?
Each contact in TFC-146-02-F-D-K-TR handles up to 3 A continuous and 125 VDC working voltage. For a typical FPGA expansion interface using 3.3 V LVCMOS signals with 12 mA drive strength per pin, the connector operates well within its voltage rating with 37x safety margin. All 92 contacts loaded simultaneously at 12 mA carry a total of 1.1 A, far below the aggregate thermal limit, ensuring signal integrity across 92 channels without thermal derating of adjacent contacts.
