What are the key features of TFC-127-02-F-D-A?
- 54-position dual-row SMT terminal strip at 0.050" (1.27 mm) pitch enabling high-density signal interconnect in compact PCB designs
- Tiger Eye contact technology delivering superior normal force for consistent contact resistance below 20 milliohms over thousands of insertion cycles
- Surface-mount footprint compatible with standard reflow soldering at up to 260°C for seamless integration into automated SMT assembly lines
- Cost-effective design within the Tiger Eye family offering high-reliability contact performance at a competitive system cost for mid-to-high volume production
What is TFC-127-02-F-D-A used for?
The TFC-127-02-F-D-A is ideal for high-density SMT interconnect in mezzanine card assemblies, daughter-board interfaces, and backplane socket applications in embedded computing, telecommunications, and industrial control systems. With 54 positions at 1.27 mm pitch, it efficiently consolidates a large signal count into a single surface-mount connector, reducing PCB area and simplifying routing on space-constrained boards. Networking equipment, data acquisition modules, and test instrumentation also use this terminal strip for its repeatable Tiger Eye contact performance.

Frequently Asked Questions
How many positions does TFC-127-02-F-D-A have and what pitch separates adjacent contacts?
The TFC-127-02-F-D-A provides 54 positions in a dual-row arrangement with a contact pitch of 0.050" (1.27 mm). This pitch allows 27 contacts per row within a very compact linear footprint, making it practical for PCB designs where board area is at a premium. The 54-position count is well-matched to signal buses in embedded microcontroller boards, FPGA expansion connectors, and mezzanine card interfaces that require routing 50 to 54 independent signals through one connector.
What soldering process is compatible with the TFC-127-02-F-D-A surface-mount footprint?
The TFC-127-02-F-D-A uses an SMT footprint rated for standard reflow soldering at peak temperatures up to 260°C, compliant with IPC-J-STD-020 moisture sensitivity requirements. It can be placed by automated pick-and-place equipment and soldered in the same reflow pass as other SMT components on the board, eliminating a separate through-hole soldering step. This compatibility makes it cost-effective for high-volume PCB assembly in consumer electronics and industrial manufacturing environments.
For a mezzanine card design needing exactly 54 signal connections, why choose TFC-127-02-F-D-A over two smaller connectors?
Using a single 54-position TFC-127-02-F-D-A instead of two 27-position or two 30-position connectors reduces the component count by 1 part per board, lowers assembly placement time, and eliminates the need to align two separate connectors during mating. A single connector also provides a more mechanically symmetric mating interface, reducing the risk of one connector engaging before the other during board insertion. This simplification can meaningfully reduce per-board cost and assembly defect rate at production volumes of thousands of units per month.
Is the TFC-127-02-F-D-A suitable for industrial environments with wide temperature ranges?
The TFC-127-02-F-D-A is designed to maintain reliable contact performance across a wide operating temperature range typical of industrial environments, generally from -55°C to +125°C for SAMTEC terminal strip products. The Tiger Eye contact geometry sustains adequate normal force throughout this range, preventing contact resistance from rising above 20 milliohms even during thermal cycling. This makes the connector appropriate for industrial PLCs, factory automation modules, and outdoor telecom equipment exposed to seasonal temperature extremes.
