What are the key features of TFM-143-22-L-D-A-P-TR?
- Right-angle (L) board mounting for lateral signal exit enabling board-to-board connection within tight vertical clearances below 10 mm
- 0.050 inch (1.27 mm) pitch dual-row design providing 86 pins in a compact connector footprint for high-density signal routing
- Tiger Eye contact system maintaining consistent low-resistance mating across environmental extremes from -55°C to +125°C
- Tape-and-reel (TR) format compatible with automated SMT assembly lines for high-volume production scalability
What is TFM-143-22-L-D-A-P-TR used for?
The TFM-143-22-L-D-A-P-TR is designed for high-density lateral board-to-board interconnects in rack-mounted industrial computers, communications equipment, and embedded defense electronics where PCB height clearance is limited. Its 86-pin dual-row layout at 0.050 inch pitch provides a high signal count through a compact right-angle SMT connector suitable for FPGA I/O buses and multi-channel data acquisition systems. The right-angle design allows front-panel connector access without requiring removal of the PCB from its housing.

Frequently Asked Questions
How does the right-angle orientation of TFM-143-22-L-D-A-P-TR benefit stacked PCB assemblies?
The right-angle (L) orientation of the TFM-143-22-L-D-A-P-TR redirects the 86-pin mating interface to exit the PCB laterally, reducing the vertical board clearance needed to less than 5 mm above the connector body compared to a vertical mounting approach requiring 10 mm or more. This allows boards to be stacked more closely together in multi-card assemblies used in compact industrial controllers and defense avionics enclosures.
What pin count and contact pitch does the TFM-143-22-L-D-A-P-TR provide for signal routing?
The TFM-143-22-L-D-A-P-TR provides 86 total pins in a dual-row arrangement at a 0.050 inch (1.27 mm) pitch, enabling engineers to route 86 individual signals through a right-angle connector spanning approximately 55 mm in length. This high pin density at fine pitch supports complex FPGA I/O expansion, high-channel ADC/DAC interfaces, and multi-bus backplane connections where minimizing connector footprint is essential.
Can the TFM-143-22-L-D-A-P-TR be used in automated SMT production, and how is it packaged?
Yes, the TFM-143-22-L-D-A-P-TR is packaged in tape-and-reel (TR) format, making it directly compatible with automated SMT pick-and-place machines. The reel presentation ensures accurate feeder alignment for the 86-pin fine-pitch body during high-speed placement, and the connector is qualified for lead-free reflow soldering at peak temperatures up to 260°C, supporting high-volume manufacturing with minimal manual handling.
When is the TFM-143-22-L-D-A-P-TR a better choice than a lower-pin-count alternative such as the TFM-138 series?
The TFM-143-22-L-D-A-P-TR with 86 pins is preferred over lower-count alternatives like TFM-138 with 76 pins when the design requires routing at least 80 or more signals through a single right-angle connector, avoiding the need for a second connector. Using a single 86-pin connector rather than two 44-pin connectors reduces the PCB area needed for connector footprints by approximately 30% and simplifies the mating operation to a single engagement point.
