What are the key features of TFC-140-02-F-D-A-K?
- 80-position dual-row layout at 0.050 inch (1.27 mm) pitch delivers 160 total contacts for high-density board-to-board signal routing in a compact connector footprint
- Tin (Sn) over nickel (Ni) barrier termination contacts provide good solderability and corrosion resistance for wave or selective soldering during PCB assembly
- K keying prevents incorrect mating orientation across multiple connectors, protecting board circuitry from misaligned insertion during assembly or field servicing
What is TFC-140-02-F-D-A-K used for?
The TFC-140-02-F-D-A-K is suited for high-density board-to-board interconnect in embedded computing modules, industrial control backplanes, and FPGA expansion boards requiring 160 contacts at 0.050 inch pitch. Its tin-over-nickel termination contacts ensure reliable soldering in wave and selective solder processes, while the K keying prevents costly assembly errors in multi-connector PCB designs. This terminal strip is commonly used in telecommunications systems, data acquisition platforms, and instrumentation boards where routing a high number of signal channels between two PCBs efficiently is essential.

Frequently Asked Questions
What is the total pin count and contact arrangement of the TFC-140-02-F-D-A-K?
The TFC-140-02-F-D-A-K is an 80-position dual-row terminal strip providing 160 total contacts at 0.050 inch (1.27 mm) pitch. This high contact count makes it well-suited for applications such as 128-bit parallel data buses, 160-channel I/O expansion cards, or multi-signal backplane interfaces requiring many simultaneous board-to-board connections in a compact footprint.
What does the K keying feature add to the TFC-140-02-F-D-A-K in multi-connector board assemblies?
The K keying in the TFC-140-02-F-D-A-K is a mechanical polarization feature that prevents the connector from being mated in an incorrect orientation. In PCB assemblies with multiple 0.050 inch pitch dual-row connectors in close proximity, the keying ensures each board can only be connected to its correct partner, protecting all 160 contacts and the connected circuitry from reverse-insertion damage during assembly or field maintenance.
What soldering process is compatible with the TFC-140-02-F-D-A-K, given its contact finish?
The TFC-140-02-F-D-A-K uses tin (Sn) over nickel (Ni) barrier termination contacts, which are compatible with wave soldering and selective soldering processes. The JESD-609 code e3 classification indicates the component meets standard moisture sensitivity requirements. The nickel barrier prevents tin migration into the base contact material, improving solder joint reliability across the 160-pin footprint in high-throughput production environments.
How does the TFC-140-02-F-D-A-K compare to the TFC-122-02-FM-D-A-K for high channel-count designs?
The TFC-140-02-F-D-A-K provides 160 total contacts versus 88 contacts in the TFC-122-02-FM-D-A-K, making it the better choice when a design requires more than 88 signal and power channels between boards—such as 128-bit memory buses or multi-channel sensor arrays with additional control lines. Both operate at 0.050 inch pitch, so the larger connector simply occupies more board length while using the same footprint style.
