Frequently Asked Questions
How many signal connections does TFC-128-02-L-D-A-K provide and at what pitch?
The TFC-128-02-L-D-A-K provides 56 signal positions arranged in 2 rows on a 0.050" (1.27 mm) pitch. This configuration is particularly efficient in FPGA expansion boards and embedded computing applications where routing 56 signals through a single compact connector reduces PCB layer count and simplifies board layout compared to using multiple smaller connectors.
For FPGA daughter-card designs, how does TFC-128-02-L-D-A-K help manage the large I/O pin count?
FPGAs with 56 or more user I/O pins frequently use 0.050" pitch dual-row connectors like TFC-128-02-L-D-A-K to bring all signals to a mating carrier board in a single compact connector. The 0.050" pitch reduces connector body length by 50% compared to 0.100" alternatives, leaving more room on the daughter card for decoupling capacitors and power circuitry around the FPGA device.
What operating temperature range is specified for TFC-128-02-L-D-A-K and does it suit industrial environments?
SAMTEC TFC-series terminal strips support an operating temperature range of -55°C to +125°C, covering the full industrial temperature grade. The TFC-128-02-L-D-A-K is therefore suitable for industrial automation, motor drive control, and outdoor instrumentation enclosures where ambient temperatures may swing well beyond the 0°C to 70°C commercial range expected of standard connectors.
When should an engineer choose TFC-128-02-L-D-A-K over a 64-position TFC connector for a 56-signal interface?
Selecting a 56-position connector sized to the exact signal count eliminates unused positions, reducing connector body length by approximately 8 positions x 0.050" = 0.400" compared to a 64-position alternative. This board-space saving is meaningful in compact embedded modules. The TFC-128-02-L-D-A-K is the cost-optimal choice when the design requires exactly 56 connections and avoids unrouted pins that could cause confusion during board bring-up.
