What are the key features of TFC-138-02-F-D-A-K?
- 76-position dual-row layout on 0.050 inch (1.27 mm) pitch provides 152 total contacts in a compact terminal strip body
- Tiger Eye bifurcated dual-beam contacts maintain 2 independent contact points per 0.025 inch square post for enhanced signal reliability
- Cost-effective construction reduces BOM cost per contact in high-channel-count embedded and instrumentation designs
What is TFC-138-02-F-D-A-K used for?
The TFC-138-02-F-D-A-K is engineered for high-density mezzanine card sockets, FPGA expansion interfaces, and multi-channel data acquisition backplanes where 152 contacts on a 0.050 inch pitch maximize signal density per unit PCB length. Its Tiger Eye dual-beam contact design ensures consistent mating with the SAMTEC TFM, TSM, and compatible square-post header families through repeated plug-in cycles. The cost-effective terminal strip format suits production designs where large contact counts must be supported at a competitive per-pin price point.

Frequently Asked Questions
How many total contacts does the TFC-138-02-F-D-A-K provide across its dual-row layout?
The TFC-138-02-F-D-A-K is a 76-position dual-row terminal strip on a 0.050 inch (1.27 mm) pitch, delivering 152 total contact positions in one connector body. This high contact count is practical for interfaces needing more than 100 individual signal or power connections, such as FPGA mezzanine sockets, high-resolution ADC modules, or multi-axis motion-controller expansion cards.
What square-post size mates with the TFC-138-02-F-D-A-K Tiger Eye contacts, and which header families are compatible?
The Tiger Eye contacts in the TFC-138-02-F-D-A-K accept 0.025 inch (0.635 mm) square posts, the standard post size for all SAMTEC 0.050 inch pitch header families including TSM, TFM, and SFM series. This broad compatibility means the TFC-138-02-F-D-A-K can mate with existing square-post headers from multiple manufacturers without requiring a custom or proprietary mating connector, simplifying multi-vendor PCB assembly.
How does selecting TFC-138-02-F-D-A-K over multiple smaller 0.050 inch terminal strips benefit PCB layout in a 150-channel design?
Consolidating 150 or more signals into a single TFC-138-02-F-D-A-K body eliminates the PCB gaps and keepout zones that appear between adjacent smaller connectors. On a 0.050 inch pitch, even a 1 mm gap between two smaller connectors creates trace-routing detours that add 2 to 5 mm of extra signal path per layer transition. A single 152-contact connector removes these gaps, shortens trace lengths, and reduces the number of solder joints that could become reliability points of failure in thermal-cycling environments.
