What are the key features of TFC-103-02-L-D-A?
- 6-position dual-row board connector on 0.050 inch (1.27 mm) pitch in a compact 0.425 x 0.225 inch body for ultra-tight PCB layouts
- Gold-over-nickel (AU on NI) mating finish providing low and stable contact resistance of 15 mΩ across extended mating cycles
- Phosphor-bronze contact material delivering superior spring force and fatigue resistance compared to brass in high-cycle connector applications
- Tin-over-nickel barrier termination finish offering excellent solderability and corrosion protection during wave or reflow PCB assembly
What is TFC-103-02-L-D-A used for?
TFC-103-02-L-D-A is designed for compact 6-signal board-to-board or wire-to-board connections in space-constrained embedded modules, sensor interface boards, and small daughtercard stacks where 0.050 inch pitch is required. Its gold mating contacts and phosphor-bronze spring material ensure reliable signal integrity in low-voltage digital and analog signal paths on densely populated PCBs. The small 0.425 x 0.225 inch body makes it ideal for fitting into IoT sensor nodes and compact medical device electronics with limited connector real estate.

Frequently Asked Questions
How many positions does TFC-103-02-L-D-A have, and what are the physical body dimensions?
TFC-103-02-L-D-A is a 6-position dual-row connector arranged with 3 contacts per row on 0.050 inch (1.27 mm) pitch. The body measures 0.425 inch in length and 0.225 inch in breadth, making it one of the smallest members of the TFC Tiger Eye family for applications needing only 6 signal connections.
What contact resistance does TFC-103-02-L-D-A specify, and why does this matter for signal integrity?
TFC-103-02-L-D-A specifies a contact resistance of 15 mΩ per contact pair. At this low resistance, even with 100 mA of current through a single contact, the voltage drop is only 1.5 mV, well within the noise budget of most digital and low-voltage analog interfaces. Gold-over-nickel mating finish maintains this low resistance over thousands of insertion and removal cycles.
Why is phosphor-bronze used for the contact material in TFC-103-02-L-D-A instead of brass?
Phosphor-bronze offers higher tensile strength and better spring-back characteristics than standard brass, allowing TFC-103-02-L-D-A contacts to maintain consistent normal force on the mating connector after repeated insertion cycles exceeding 200 mates. This material choice is particularly important in development boards and test fixtures where connectors are frequently disconnected.
For a compact IoT module needing 6 board-to-board connections on a 0.050 inch pitch, when would TFC-103-02-L-D-A be selected over a single-row alternative?
TFC-103-02-L-D-A's dual-row layout places all 6 contacts in a 0.425 inch body length, while an equivalent single-row 0.050 inch part would require 0.300 inch of extra length to carry the same 6 signals. For a PCB that is critically width-constrained, the 0.225 inch wide dual-row footprint of TFC-103-02-L-D-A is preferred over a single-row layout that would extend further along the board edge.
