Key Features
- 98-position dual-row configuration at 0.050-inch (1.27 mm) pitch delivering extremely high signal density for compact embedded and backplane designs
- Tiger Eye low-insertion-force contact technology ensures reliable mating and unmating across all 98 positions with consistent signal integrity
- Tape-and-reel (TR) packaging with low-profile LM option enables automated SMT assembly for high-volume production environments
Applications
The TFC-149-02-LM-D-A-K-TR is suited for high-density board-to-board and daughter card connections in server motherboards, FPGA development platforms, and multi-channel data acquisition systems requiring 98 signals in minimal PCB real estate. Its 0.050-inch dual-row pitch supports routing large signal buses and control interfaces on compact modules where standard 0.100-inch pitch connectors would consume excessive board area. The tape-and-reel format enables efficient automated assembly in volume manufacturing.

Frequently Asked Questions
How many signal positions does the TFC-149-02-LM-D-A-K-TR support, and what pitch does it use?
The TFC-149-02-LM-D-A-K-TR provides 98 positions in a dual-row layout with a 0.050-inch (1.27 mm) pitch, enabling 98 individual signal connections within a compact PCB footprint. This makes it well suited for high-channel-count data buses, FPGA I/O expansion headers, and multi-lane signal interfaces where board space is tightly constrained.
Which system-level applications benefit most from using TFC-149-02-LM-D-A-K-TR over lower-count connectors?
Applications requiring 98 or more parallel signal connections — such as FPGA prototype boards, server memory expansion modules, and multi-axis motion control systems — benefit from this connector's 98-pin dual-row design. Using a single TFC-149-02-LM-D-A-K-TR instead of multiple smaller 0.050-inch connectors reduces assembly steps and minimizes connector-to-connector variation across the 98-signal interface.
What packaging does TFC-149-02-LM-D-A-K-TR ship in, and how does it support high-volume SMT assembly?
The -TR suffix indicates tape-and-reel packaging, feeding directly into standard SMT pick-and-place machines for automated placement of the 98-position dual-row connector. This packaging option reduces manual loading errors and enables consistent orientation of the low-profile (LM) variant across high-volume PCB assembly runs, improving throughput for large production batches.
