Key Features
- 6-position dual-row male connector at 0.050" (1.27 mm) pitch with tin (Sn) over nickel (Ni) barrier termination for improved solder joint reliability and corrosion resistance
- Tiger Eye dual-beam contact design delivers consistent mating force and contact resistance below 20 mΩ in a very compact 6-circuit footprint
- JESD-609 e3 RoHS-compliant construction meets lead-free manufacturing requirements for global product compliance
Applications
The TFC-103-02-F-D-A-K is deployed in ultra-compact PCB assemblies, sensor breakout boards, and small IoT module interconnects where only 6 signal circuits need to pass through a minimal connector body at 1.27 mm pitch. Its small 6-position size makes it ideal for power-plus-signal dual-row connections in embedded modules with extremely tight board space constraints. The tin-over-nickel termination supports reliable lead-free soldering in consumer electronics and industrial miniature sensor products.

Frequently Asked Questions
Why does the TFC-103-02-F-D-A-K use a tin-over-nickel termination rather than plain tin, and what advantage does this provide?
The TFC-103-02-F-D-A-K uses a tin (Sn) over nickel (Ni) barrier termination, where the nickel underplate acts as a diffusion barrier between the copper contact alloy and the tin outer layer. This prevents tin whisker growth and tin-copper intermetallic formation that can degrade solder joint reliability at temperatures above 100°C. The nickel barrier also extends the shelf life of the 6-position connector by preventing base-metal migration, ensuring consistent lead-free solderability even after 12 months of storage at standard conditions.
For a sensor breakout board needing only 6 signal connections at 1.27 mm pitch, what board area does the TFC-103-02-F-D-A-K occupy?
The TFC-103-02-F-D-A-K in a 6-position dual-row 1.27 mm pitch configuration occupies a PCB footprint of approximately 5 mm in length (3 contacts per row at 1.27 mm spacing) and under 6 mm in width, consuming less than 30 mm² of board area. This is significantly smaller than a 6-position 2.54 mm pitch alternative, which would require roughly 10 mm of length. The compact footprint is critical for coin-cell-sized sensor modules and wearable-electronics PCBs where board area is limited to a few hundred square millimeters.
What JESD-609 compliance level does the TFC-103-02-F-D-A-K carry, and why is this relevant for CE-marked product export?
The TFC-103-02-F-D-A-K carries JESD-609 code e3, indicating it is a lead-free (Pb-free) component with a moisture sensitivity level compatible with standard IPC/JEDEC reflow profiles. For CE-marked products exported to the European Union, e3-coded components satisfy the RoHS Directive 2011/65/EU requirements for absence of lead in homogeneous materials below 0.1 percent by weight. Using e3-compliant connectors across the BOM simplifies the Declaration of Conformity process and avoids RoHS annex exemption paperwork, reducing compliance overhead for small-quantity product launches.
