Key Features
- 54-position dual-row configuration on 0.050" (1.27 mm) pitch delivers high signal density for compact PCB interconnect designs
- Tiger Eye contact technology provides enhanced normal contact force for reliable mating performance over extended insertion cycles
- Cost-effective terminal strip design reduces per-pin connector cost while maintaining SAMTEC quality and dimensional precision
Applications
The TFC-127-02-L-D-A-K is suited for high-density board-to-board and wire-to-board interconnect applications in telecommunications, computing, and industrial electronics where 54 positions must be routed in a compact 1.27 mm pitch layout. Its Tiger Eye contacts make it compatible with SAMTEC's TSM and SFM series mating headers, enabling flexible system design with reliable signal integrity across 54 dual-row connections. The right-angle through-hole termination simplifies routing on horizontal PCB stacking configurations.

Frequently Asked Questions
How many positions does TFC-127-02-L-D-A-K offer, and what is the connector pitch?
The TFC-127-02-L-D-A-K provides 54 total positions arranged in a dual-row layout on a 0.050" (1.27 mm) pitch. This compact pitch enables routing of 54 signals in a body length of approximately 1.35 inches, making it efficient for high-density mezzanine or backplane interconnects where PCB real estate is at a premium.
What mating connectors are compatible with the TFC-127-02-L-D-A-K terminal strip?
The TFC-127-02-L-D-A-K mates with SAMTEC's SFM and TSM series socket strips designed for 0.050" (1.27 mm) pitch dual-row configurations. These mating sockets also use Tiger Eye contacts, ensuring a matched normal-force pair that sustains low contact resistance below 20 mΩ across up to 500 mating cycles. This compatibility extends to most industry-standard 1.27 mm pitch dual-row receptacles.
When should designers choose TFC-127-02-L-D-A-K over higher-pitch alternatives for a 54-pin interface?
Designers should choose the TFC-127-02-L-D-A-K when board space constraints require fitting 54 signals into a footprint that a 2.00 mm or 2.54 mm pitch connector cannot accommodate. At 1.27 mm pitch, the TFC series reduces connector length by approximately 30% compared to 2.00 mm pitch alternatives, which is decisive for compact PCBs in handheld instruments, network switches, or densely populated industrial controllers operating up to 125°C.
