What are the key features of TFC-143-02-FM-D-A-K?
- 86-position dual-row layout at 1.27 mm (0.050") pitch delivers very high density interconnect within a minimal PCB area
- Polarization key (K) ensures correct connector insertion, preventing reverse-orientation assembly errors in 86-pin interfaces
- Flat-mount (FM) SMT termination is compatible with standard reflow oven processes, enabling fully automated PCB assembly
- Tiger Eye cost-effective contact design maintains reliable electrical performance over thousands of mating cycles
What is TFC-143-02-FM-D-A-K used for?
The TFC-143-02-FM-D-A-K is designed for high-density mezzanine, daughtercard, and module-to-motherboard interconnect in embedded computing, industrial control, and communication platforms. Its 86-position dual-row configuration at 1.27 mm pitch with keying is ideal for high channel-count signal buses, backplane interfaces, and test fixture connections where precise mating alignment is required.

Frequently Asked Questions
How many pins does the TFC-143-02-FM-D-A-K have, and how are they arranged across the connector?
The TFC-143-02-FM-D-A-K provides 86 positions in a dual-row (D) layout, with 43 contacts per row at a 1.27 mm (0.050") center pitch. This high-density arrangement allows 86 individual signals or power lines to be routed within the connector's compact SMT footprint.
When should a designer choose TFC-143-02-FM-D-A-K over a standard 0.1-inch pitch connector for a high pin-count interface?
At 1.27 mm (0.050") pitch, the TFC-143-02-FM-D-A-K occupies roughly 40% less board length than a 2.54 mm (0.1") pitch equivalent for the same 86-pin count. This makes it preferable in space-constrained PCB designs such as compact embedded modules and high-density backplanes where saving several centimeters of connector length is critical.
What does the K suffix indicate on TFC-143-02-FM-D-A-K, and why is it important for high pin-count connectors?
The K suffix denotes an integrated polarization key that prevents the mating connector from being inserted backwards or in the wrong position. For an 86-position dual-row connector at 1.27 mm pitch, this is especially important because misalignment can damage 86 signal pins simultaneously, making keying a critical safeguard during board assembly and field maintenance.
