What are the key features of TFC-110-02-LM-D-A?
- 20-position dual-row male terminal strip on 0.050" (1.27 mm) pitch in a tiny 0.625 " x 0.225" body for ultra-compact PCBs
- Gold (15 µin) plated phosphor bronze mating contacts ensure low contact resistance and extended mating cycle life
- Tin-over-nickel barrier termination contacts deliver reliable lead-free solder adhesion during reflow assembly
What is TFC-110-02-LM-D-A used for?
The TFC-110-02-LM-D-A is deployed in miniaturized embedded computing boards, sensor fusion modules, and compact FPGA daughter cards where 20-circuit fine-pitch male connectors provide dense board-to-board signal paths in enclosures too small for .100" pitch headers. Its 0.625 inch body length and gold-plated contacts make it a cost-effective yet reliable interconnect for space-critical PCB stacking designs.

Frequently Asked Questions
What are the physical dimensions and contact specifications of the TFC-110-02-LM-D-A connector?
The TFC-110-02-LM-D-A body measures 0.625 inches long, 0.225 inches wide, and 0.226 inches deep, making it one of the most compact 20-position dual-row connectors available at 0.050" pitch. Mating contacts are gold-plated to 15 µin on phosphor bronze, providing both electrical reliability and mechanical spring retention across hundreds of mating cycles.
Why are phosphor bronze contacts with gold plating used in the TFC-110-02-LM-D-A, and what mating longevity do they provide?
Phosphor bronze offers a superior combination of electrical conductivity and spring-back force compared to brass, maintaining consistent contact pressure at 0.050" pitch where contact size is inherently small. The 15 µin gold plating on mating surfaces eliminates oxide film formation, ensuring contact resistance below a few milliohms and reliable signal integrity across a rated life of at least 200 to 500 mating cycles depending on application conditions.
How does the 0.050" pitch of the TFC-110-02-LM-D-A enable higher circuit density compared to .100" pitch headers of similar pin count?
At 0.050" (1.27 mm) pitch, the TFC-110-02-LM-D-A packs 20 positions into a 0.625 inch body length, whereas a .100" pitch connector carrying the same 20 positions would need approximately 1.0 inch. This nearly 40% reduction in connector footprint frees critical PCB area for routing, decoupling capacitors, or additional ICs in compact designs such as wearables, IoT nodes, and miniature industrial controllers.
