What are the key features of TFC-123-02-FM-D-A-K-TR?
- 46-position dual-row layout at 0.050-inch (1.27 mm) pitch provides twice the contact density of standard 0.100-inch connectors
- Tiger Eye contact design delivers cost-effective mating performance with reliable low-insertion-force contact retention
- Female (FM) mating contact style mates with standard 0.050-inch pitch male headers for secure board-to-cable connections
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly for medium and high production volumes
- Dual-row (D) and A-key polarization option prevents mismating in densely populated 0.050-inch pitch connector fields
What is TFC-123-02-FM-D-A-K-TR used for?
The TFC-123-02-FM-D-A-K-TR is ideal for high-density board-to-cable assemblies in telecommunications equipment, server backplanes, and embedded computing modules where 0.050-inch pitch minimizes connector footprint. Its 46-position dual-row configuration carries 46 signal lines within roughly the same PCB area as a 23-position single-row 0.100-inch connector, enabling significant board space savings. The tape-and-reel format streamlines automated assembly in volume production of network switches, storage controllers, and industrial I/O boards.

Frequently Asked Questions
How does the 0.050-inch pitch of the TFC-123-02-FM-D-A-K-TR compare to standard 0.100-inch connectors in terms of board space savings?
At 0.050-inch (1.27 mm) pitch, the TFC-123-02-FM-D-A-K-TR occupies roughly half the linear board space per contact compared to a standard 0.100-inch pitch connector. A 46-position dual-row 0.050-inch strip requires approximately 1.2 inches of PCB length, whereas an equivalent-count 0.100-inch connector would need over 2.3 inches, freeing significant area in compact PCB layouts.
What does the A-key feature on the TFC-123-02-FM-D-A-K-TR prevent during cable harness assembly?
The A-key polarization notch creates an asymmetric keying feature that physically prevents a mating cable connector from being inserted rotated 180 degrees. In a 46-position dual-row 0.050-inch pitch assembly, reversed insertion would misconnect 46 signal nets. The keying feature eliminates this risk in field wiring and automated harness-assembly operations.
For a telecommunications line card requiring 46 differential signal pairs in a compact form factor, how does the TFC-123-02-FM-D-A-K-TR address the routing challenge?
The dual-row, 0.050-inch pitch layout of the TFC-123-02-FM-D-A-K-TR places 46 contacts in two staggered rows, maintaining a contact-to-contact spacing of 1.27 mm. This allows differential pairs to be routed side-by-side within the connector footprint without crosstalk-inducing vias, and the female mating contacts provide low-resistance connections below 50 mΩ typical for high-speed differential signal integrity.
