What are the key features of TFC-131-02-FM-D-A?
- 62-position dual-row layout at 0.050-inch (1.27 mm) pitch places 31 contacts per row, enabling high signal density in compact PCB interconnect footprints
- Tiger Eye low-insertion-force contact mechanism reduces cumulative mating load across all 62 positions, protecting delicate PCB pads and solder joints during repeated assembly
- Cost-effective FM (female) variant of the TFC terminal strip series supports affordable high-channel-count mating to matching male headers in volume production designs
What is TFC-131-02-FM-D-A used for?
The TFC-131-02-FM-D-A is well suited for board-to-board interconnects in FPGA mezzanine cards, embedded processor expansion buses, and laboratory data acquisition systems that route 62 signal channels across mating PCBs at a 1.27 mm pitch. Industrial motion control boards and test fixture interface panels benefit from its Tiger Eye low-insertion-force contacts, which support repeated mating cycles without degrading contact reliability on the 62-pin interface.

Frequently Asked Questions
How many contacts does TFC-131-02-FM-D-A provide per row, and what is its overall position count?
The TFC-131-02-FM-D-A provides 31 contacts per row in a dual-row configuration for a total of 62 positions at a 0.050-inch (1.27 mm) pitch. The dual-row layout reduces the physical connector length needed to accommodate 62 signal channels, saving PCB edge space compared to any equivalent single-row strip.
What does the FM designation in TFC-131-02-FM-D-A indicate about the connector gender?
The FM designation indicates a female contact configuration designed to mate with the corresponding male TFC-131-02-LM or similar male-pin variant. This female terminal strip accepts 0.025-inch (0.635 mm) square posts or compatible male pins at the 1.27 mm pitch, forming a secure mechanical and electrical connection across all 62 signal positions.
In an FPGA mezzanine card design, how does TFC-131-02-FM-D-A handle signal routing across 62 channels?
On an FPGA mezzanine card, TFC-131-02-FM-D-A can carry up to 62 individual I/O signals — including differential pairs, single-ended control lines, and power distribution pins — through a single dual-row connector at 1.27 mm pitch. The compact footprint keeps trace routing distances short, reducing parasitic inductance and supporting signal speeds up to several hundred MHz on the mezzanine interface.
How does the 1.27 mm pitch of TFC-131-02-FM-D-A compare to 2.0 mm pitch connectors for the same channel count?
At 1.27 mm pitch, the 62-position TFC-131-02-FM-D-A occupies roughly 39 mm of board length per row, whereas a 2.0 mm pitch connector for the same 62 channels would require approximately 62 mm per row — a 60% increase. Choosing 1.27 mm pitch frees significant board edge space in mixed-signal PCBs where multiple connectors must coexist in limited available length.
