Frequently Asked Questions
What contact finish does the TFC-125-02-L-D-A-K use and why does it matter for soldering processes?
The TFC-125-02-L-D-A-K uses a tin-over-nickel (Sn/Ni) contact finish rated to JESD-609 e3, which ensures reliable wettability during reflow and wave soldering at standard peak temperatures around 260°C. The nickel barrier prevents diffusion between the tin finish and the copper base, maintaining joint integrity and reducing whisker growth risk over the connector's service life.
How does the 50-position dual-row layout of TFC-125-02-L-D-A-K support FPGA or wide parallel bus routing?
With 50 positions at 0.050" (1.27 mm) pitch arranged in 2 rows, this connector accommodates 32-bit or wider parallel data buses plus dedicated power, ground, and control lines within a single mated pair. FPGA carrier boards and data acquisition modules benefit from routing all bus signals through a single compact connector rather than multiple smaller connectors, reducing PCB routing complexity and BOM count.
Is the TFC-125-02-L-D-A-K suitable for applications with regulatory compliance requirements?
Yes, the TFC-125-02-L-D-A-K is REACH compliant and carries a JESD-609 e3 moisture sensitivity rating, making it suitable for industrial and commercial applications subject to EU REACH and RoHS regulations. The tin-over-nickel finish avoids restricted substances, and the JESD-609 e3 classification ensures the connector meets standard moisture sensitivity handling requirements for surface-mount assembly.
When is TFC-125-02-L-D-A-K a better cost choice than SAMTEC's high-frequency SEARAY connectors for the same 50-position interface?
TFC-125-02-L-D-A-K is the better choice when operating signal frequencies stay below 500 MHz and there is no requirement for controlled 50-ohm or 100-ohm differential impedance. SEARAY connectors are designed for multi-GHz differential signals with matched impedance, which carries a higher cost per position. For standard parallel bus interfaces at lower frequencies, the Tiger Eye design provides equivalent connectivity at a significantly lower price per contact.
