What are the key features of TFM-142-05-FM-D-LC?
- Tiger Eye multi-finger contact design maintains reliable grip on mating pins across hundreds of mating cycles, minimizing contact resistance in dual-row 42-position configurations
- Low-clearance (LC) profile reduces stack height in space-constrained assemblies while preserving the 0.050 inch (1.27 mm) pitch signal density of 84 total contacts
- Friction-mount (FM) retention system provides mechanical stability during PCB handling and reflow, preventing connector shift prior to final soldering
What is TFM-142-05-FM-D-LC used for?
The TFM-142-05-FM-D-LC is designed for high-reliability board-to-board interconnect in aerospace electronics, defense systems, and industrial automation equipment where contact retention under vibration and thermal cycling is mandatory. Its low-clearance profile and 42-position dual-row layout make it well suited for compact daughtercard-to-backplane and module-to-baseboard assemblies requiring high signal density. The Tiger Eye contact technology also makes it a strong candidate for test and measurement equipment that undergoes repeated connector mating during calibration and maintenance cycles.

Frequently Asked Questions
What does the low-clearance (LC) designation mean for the TFM-142-05-FM-D-LC, and how does it affect board stack height?
The LC (low-clearance) designation indicates the connector has a reduced above-board profile compared to standard TFM variants, enabling tighter board-to-board spacing in multi-layer stack assemblies. This is critical in portable defense electronics or avionics modules where enclosure height is limited and the 0.050 inch (1.27 mm) pitch must be preserved while minimizing the overall assembly envelope across 84 contact positions.
How does the friction-mount (FM) feature of the TFM-142-05-FM-D-LC benefit PCB assembly processes?
The friction-mount feature uses mechanical interference between the connector housing and the PCB holes to hold the connector in place before soldering, eliminating the need for additional fixture tooling or adhesive. This is particularly valuable during automated reflow or wave soldering of 42-position dual-row connectors at 0.050 inch pitch, reducing placement shifts that could cause solder bridges or misaligned contacts across the 84-pin footprint.
In which signal density scenarios does the TFM-142-05-FM-D-LC outperform a single-row 0.100 inch pitch alternative?
The TFM-142-05-FM-D-LC provides 84 contacts (42 positions x 2 rows) at 0.050 inch pitch, fitting into roughly half the board length required by a single-row 0.100 inch pitch connector with equivalent contact count. This makes it the preferred choice in high-density signal routing for FPGA daughtercards, DSP modules, and radar processing boards where saving 20 mm or more of connector footprint length directly enables smaller system form factors.
