Key Features
- 26-position dual-row board stacking connector at 0.050-inch (1.27mm) pitch for high-density board-to-board interconnection
- Gold (10µin) mating contact finish ensures low contact resistance and resistance to oxidation over thousands of mating cycles
- Tiger Eye cost-effective series delivers reliable stacking connectivity at reduced cost compared to premium high-cycle-life alternatives
Applications
The SAMTEC TFC-113-02-L-D is designed for board stacking applications in embedded computing, instrumentation, and modular industrial controllers where a 26-position dual-row 0.050-inch pitch connector must reliably interconnect two PCBs at minimum cost. Its gold-plated mating contacts and matte tin solder tails suit high-volume production environments such as communications daughtercard assemblies, evaluation boards, and stackable expansion modules where signal integrity and mechanical alignment over the board stack are priorities.

Frequently Asked Questions
What pitch and position count does the TFC-113-02-L-D provide for board stacking designs?
The TFC-113-02-L-D offers 26 positions arranged in a dual-row layout at 0.050-inch (1.27mm) pitch. This gives designers 26 signal or power contacts on a board stacking footprint spanning approximately 16.5mm, making it well suited for dense daughtercard and mezzanine card assemblies where a high contact count must fit within a compact PCB-to-PCB stack zone.
Why is a gold (10µin) mating contact finish specified for the TFC-113-02-L-D, and how does it compare to tin-plated contacts?
The 10µin gold plating on the mating contacts of the TFC-113-02-L-D provides lower and more stable contact resistance than tin-plated alternatives, typically maintaining contact resistance below 30mΩ even after 500 or more mating cycles. Gold resists oxide layer formation that would increase contact resistance on tin surfaces over time, which is critical in board stacking connectors that may be mated and unmated frequently during testing or field maintenance.
Which assembly process applies to the matte tin termination on the TFC-113-02-L-D, and is it RoHS compliant?
The matte tin (Sn) solder tail termination on the TFC-113-02-L-D is compatible with standard through-hole wave soldering and hand soldering at typical lead-free process temperatures. The Pb-free code indicates full RoHS compliance, so the connector integrates into lead-free assembly lines without requiring exemption documentation. Matte tin on the tails also provides better solderability consistency compared to bright tin at high-volume throughput rates.
How does the Tiger Eye cost-effective series positioning of the TFC-113-02-L-D benefit procurement for high-volume production?
The Tiger Eye cost-effective series is SAMTEC's value-oriented line targeting designs where a full 0.050-inch pitch board stacking connector is required but the cycle-life demands are moderate, typically 30 to 100 mating cycles over the product lifetime. At higher quantities — typically 1,000 units or more — the TFC-113-02-L-D is priced 20% to 40% below equivalent premium-tier SAMTEC stacking products with identical 26-position 0.050-inch pitch footprints, lowering total BOM cost without sacrificing electrical performance.
