What are the key features of TFM-145-02-FM-D-LC?
- 90-position dual-row SMT layout at 0.050 inch (1.27 mm) pitch enables very high pin density for complex FPGA and SoC module interfaces
- Tiger Eye contact technology delivers dual wipe action per pin, ensuring stable low contact resistance in high-reliability aerospace and defense applications
- Vertical low-clearance (LC) surface-mount configuration minimizes PCB stack height in multi-board embedded assemblies
What is TFM-145-02-FM-D-LC used for?
The TFM-145-02-FM-D-LC is engineered for demanding high-density board stacking applications in aerospace, defense avionics, and advanced embedded computing where 90 pins at 0.050 inch pitch provide extensive signal and power interconnection in a compact vertical SMT footprint. Its Tiger Eye contact design is specified for systems requiring consistent electrical performance across thousands of mating cycles and varying thermal environments. This connector is commonly found on FPGA mezzanine cards, data acquisition modules, and high-speed communication boards where reliability and pin density are both critical.

Frequently Asked Questions
How does the 90-position count of the TFM-145-02-FM-D-LC compare to lower-count TFM series connectors for FPGA designs?
With 90 positions in a dual-row (2x45) arrangement at 0.050 inch (1.27 mm) pitch, the TFM-145-02-FM-D-LC offers significantly more I/O bandwidth than the 14-position TFM-107 or 28-position TFM-114 variants. For high-pin-count FPGAs or SoCs requiring extensive bus, data, and control signal routing on a mezzanine card, 90 pins allow a single connector to handle multiple functional interfaces simultaneously.
What makes the Tiger Eye contact design in the TFM-145-02-FM-D-LC suitable for high-cycle aerospace applications?
Tiger Eye contacts perform a dual wipe on each of the 90 pins during every mating operation, removing oxide layers and particulate contamination to maintain contact resistance well below 20 milliohms even after repeated insertions. This dual wiping is critical in aerospace board swap scenarios where connectors may be mated and unmated hundreds of times during maintenance and testing across wide temperature ranges from -55°C to +125°C.
Is the TFM-145-02-FM-D-LC a drop-in replacement for competing 90-pin 1.27 mm pitch SMT connectors?
The TFM-145-02-FM-D-LC follows a 0.050 inch (1.27 mm) pitch dual-row SMT vertical footprint, which is common across several connector manufacturers at 90 positions. However, the Tiger Eye contact geometry and low-clearance body dimensions are SAMTEC-specific, so PCB footprints and mating connector selections should be verified against SAMTEC's official drawing before substituting from other brands. SAMTEC offers free CAD models and application support to confirm compatibility.
