What are the key features of TFC-147-02-LM-D-K-TR?
- 188 positions (94 per row) at 0.050-inch pitch for very high-density dual-row right-angle mid-mount interconnects
- Right-angle mid-mount (LM) termination delivering a reduced stack height versus standard right-angle variants
- Polarizing key (K) preventing reversed-orientation mating errors across all 188 signal positions
- Tape-and-reel (TR) packaging enabling automated pick-and-place assembly for high-volume production runs
What is TFC-147-02-LM-D-K-TR used for?
The TFC-147-02-LM-D-K-TR is designed for high-density board-edge backplane interconnects, FPGA daughtercard expansion headers, and industrial automation I/O buses where 188 low-profile, keyed, right-angle signal connections are required at 0.050-inch pitch. Its tape-and-reel format and Tiger Eye contacts make it suitable for high-volume automated assembly of telecommunications line cards, data acquisition front-ends, and multi-axis motion control backplanes where assembly accuracy and mating reliability are both critical.

Frequently Asked Questions
How does the mid-mount right-angle (LM) termination of the TFC-147-02-LM-D-K-TR reduce overall PCB assembly height?
The LM (mid-mount) designation means the connector body is positioned lower on the PCB than a standard L (right-angle) variant, reducing the protrusion height above the board surface by approximately 30 to 50 percent depending on housing geometry. In stacked PCB assemblies or enclosures with tight lid clearances of less than 10 mm, this profile reduction is essential for achieving the required board-to-board spacing while still providing a 188-position right-angle mating interface at the card edge.
What role does the polarizing key play when mating the TFC-147-02-LM-D-K-TR in a high-channel-count backplane?
With 188 positions carrying mixed signal types — such as 32-bit parallel data, address lines, clock signals, and power rails — mating the connector in the wrong orientation could route 3.3 V logic signals to power pins or vice versa, damaging multiple ICs simultaneously. The K polarizing key physically blocks reversed insertion, making a mating error mechanically impossible. In automated board assembly or field-service environments where the 188-pin connector must be mated quickly under time pressure, the key provides a zero-cost insurance mechanism against costly rework.
What automated assembly advantages does the TR packaging of the TFC-147-02-LM-D-K-TR provide compared to bulk or tray packaging?
Tape-and-reel packaging orients each connector identically in the carrier tape at a defined pitch, allowing pick-and-place machines to feed, pick, and place parts continuously without manual tray changes or re-orientation. For a 188-position connector placed on boards produced in batches of 1,000 or more, this eliminates operator intervention between placements, reduces misplacement rates to below 50 parts per million, and shortens total assembly cycle time. The reel format also protects connector contacts from electrostatic discharge during storage and transit.
For a 180-signal FPGA expansion interface, how does the TFC-147-02-LM-D-K-TR compare to using multiple smaller connectors?
The TFC-147-02-LM-D-K-TR provides 188 positions in one part, covering a 180-signal FPGA interface with 8 spare pins for ground or power without requiring multiple connectors. Using, for example, four 47-position connectors instead would require 4 separate land patterns, 4 mating operations, and 4 entries in the BOM, increasing board area consumption, mating risk, and procurement complexity. A single 188-position connector at 0.050-inch pitch keeps all FPGA I/O on one mated pair, simplifying board layout and reducing the total connector system cost per signal channel.
