What are the key features of TFM-142-22-SM-D-A-P-TR?
- 84-position dual-row .050" (1.27 mm) pitch Tiger Eye SMT terminal strip for high-density board-to-board signal interconnect
- Standard SMT solder tail (SM) termination is compatible with conventional reflow soldering processes, simplifying PCB assembly qualification
- Alignment post (A) and polarization (P) options eliminate connector mismatement errors during automated SMT pick-and-place and manual board assembly
What is TFM-142-22-SM-D-A-P-TR used for?
The TFM-142-22-SM-D-A-P-TR serves high-reliability board-to-board interconnect in aerospace avionics, defense computing modules, and high-performance server backplanes where 84 pins at .050" pitch deliver maximum signal density. Its Tiger Eye contact technology maintains stable low-resistance connections through thousands of mate-unmate cycles, making it suitable for reconfigurable test and measurement equipment. The alignment post and polarization features ensure consistent connector orientation during automated reflow assembly and field maintenance operations.

Frequently Asked Questions
How many pins does the TFM-142-22-SM-D-A-P-TR provide, and what pitch does it use?
The TFM-142-22-SM-D-A-P-TR offers 84 positions arranged in 2 rows at a .050" (1.27 mm) pitch, enabling high-density signal routing in a footprint significantly smaller than comparable 2.54 mm pitch connectors used in aerospace avionics, defense electronics, and high-speed computing boards.
How does the SM standard SMT termination of the TFM-142-22-SM-D-A-P-TR differ from the STL long-tail variant, and when should designers choose SM?
The SM suffix designates a standard-length SMT solder tail optimized for reflow soldering on flat PCB pads, whereas the STL variant provides a longer tail for improved solder fillet height on warped boards. The SM termination is the preferred choice when board flatness is within ±0.1 mm and conventional solder paste thickness is used in volume production.
What role do the alignment post and polarization features play in the TFM-142-22-SM-D-A-P-TR during PCB assembly?
The A suffix adds a physical alignment post that registers the connector body to a matching PCB hole, keeping placement accuracy within ±0.05 mm during reflow, while the P suffix provides a polarization key that prevents 180-degree rotation errors and protects the 84 signal pins from reverse-mating damage on populated boards.
