What are the key features of TFC-123-02-F-D-A?
- 46-position dual-row male connector at 0.050" (1.27 mm) pitch with gold (flash) mating contacts on phosphor bronze for low and stable contact resistance
- Matte tin (Sn) termination finish is compatible with standard lead-free wave and selective soldering processes for efficient PCB assembly
- Body length of 1.275 inch (32.4 mm) with 0.225 inch breadth provides a compact footprint for 46-circuit dual-row board interconnect
What is TFC-123-02-F-D-A used for?
The TFC-123-02-F-D-A is used in signal-dense board-to-board applications including embedded computing modules, FPGA development cards, and industrial sensor interface boards requiring 46 reliable contacts within a 32 mm connector body. Its gold-plated mating contacts maintain low contact resistance over many insertion cycles, making it suitable for test fixtures and modular equipment subject to repeated connector mating. The phosphor bronze contact material provides excellent spring-back characteristics and long-term retention of mating force.

Frequently Asked Questions
What contact materials and finishes are used on the TFC-123-02-F-D-A and how do they affect soldering and mating performance?
The TFC-123-02-F-D-A uses phosphor bronze contact material with a gold (flash, grade 3) finish on the mating surfaces and matte tin (Sn) on the termination (PCB solder) surfaces. Gold mating contacts ensure contact resistance stays low — typically under 20 mΩ — even after 200 or more insertion cycles, while the matte tin termination finish is fully compatible with SAC305 lead-free wave soldering processes at standard peak temperatures of 250°C to 260°C.
For a 46-circuit embedded module interface at 1.27 mm pitch, how does the TFC-123-02-F-D-A body size compare to a 2.54 mm pitch alternative?
The TFC-123-02-F-D-A body measures 1.275 inches (32.4 mm) long and 0.225 inch (5.7 mm) wide to accommodate all 46 positions at 1.27 mm pitch. An equivalent 46-position dual-row connector at 2.54 mm pitch would require a body approximately 64.8 mm long — exactly double. This halving of connector length is critical in compact embedded module designs where PCB edge zones are limited to 35 mm or less and every millimeter of board space counts.
How does the Tiger Eye contact design of the TFC-123-02-F-D-A benefit test fixture applications with frequent mating cycles?
In test fixture environments where a connector may be mated and unmated dozens of times per day, the Tiger Eye dual-beam contact geometry of the TFC-123-02-F-D-A maintains consistent normal force and wiping action across 200 or more mating cycles. The gold-plated phosphor bronze contacts resist fretting corrosion better than single-beam tin contacts, keeping contact resistance stable below 20 mΩ over the fixture's service life. This reduces false test failures caused by connector degradation in high-cycle automated test equipment.
