What are the key features of TFM-142-22-LM-D-A-P-TR?
- 0.050-inch (1.27 mm) pitch dual-row terminal strip delivers 2x contact density versus 0.100-inch alternatives in the same PCB footprint
- Tiger Eye contact design provides high-reliability wiping action for consistent low-resistance mating across thousands of insertion cycles
- Low-profile SMT mounting minimizes stack height in board-to-board interconnect systems requiring less than 5 mm clearance
- Tape-and-reel (-TR) packaging enables automated high-volume pick-and-place SMT assembly with standard EIA-481 feeders
What is TFM-142-22-LM-D-A-P-TR used for?
The TFM-142-22-LM-D-A-P-TR is designed for high-density board-to-board and module-to-backplane interconnect applications in military, aerospace, and industrial computing systems where reliable signal integrity across 84 contacts is critical. Its Tiger Eye contact geometry and 0.050-inch pitch make it a preferred choice for FPGA mezzanine cards, test and measurement instrumentation, and compact embedded computing modules. The dual-row 42-position configuration supports simultaneous transmission of power, ground, and high-speed differential signals in a single compact connector footprint.

Frequently Asked Questions
What contact pitch and total pin count does the TFM-142-22-LM-D-A-P-TR provide?
The TFM-142-22-LM-D-A-P-TR uses a 0.050-inch (1.27 mm) pitch in a dual-row configuration with 42 positions per row, giving a total of 84 contacts. This high-density pitch is half the spacing of standard 0.100-inch connectors, enabling 84 signals in the board space that a 42-pin single-row 0.100-inch connector would use.
What makes the Tiger Eye contact design in the TFM-142-22-LM-D-A-P-TR suitable for high-reliability applications?
The Tiger Eye contact geometry provides a dual-wipe action that displaces surface contamination and oxides during mating, maintaining contact resistance below 30 mΩ even after repeated insertion cycles. This wiping mechanism is especially valuable in aerospace and military applications where connectors may experience vibration, thermal cycling between -55°C and +125°C, and infrequent but critical mating cycles.
Which mating connector family pairs with the TFM-142-22-LM-D-A-P-TR for board-to-board stacking?
The TFM series terminal strips mate with SAMTEC TFM-compatible receptacle headers such as the TSM, SSM, and SFM series configured for 0.050-inch pitch dual-row layouts. Mating stack heights are available from approximately 3.2 mm to over 15 mm depending on the receptacle selected, supporting flexible board separation in compact stacked PCB assemblies.
How does the -A-P suffix option affect the TFM-142-22-LM-D-A-P-TR's assembly and performance?
In SAMTEC's TFM series nomenclature, the -A suffix indicates an optional alignment post and the -P suffix designates polarization features that prevent incorrect connector mating. These mechanical keying features reduce assembly errors in automated board-stuffing processes, ensuring correct orientation among 84 pins during SMT reflow and preventing potential short circuits from reversed connector installation.
