Applications
The TFC-136-02-F-D-A-K is used in cost-sensitive high-density applications such as industrial control cards, communication backplanes, and data acquisition boards requiring 72-pin connectivity at 1.27 mm pitch. Its Tiger Eye contact design balances low cost with reliable electrical performance for prototyping and volume production alike. Embedded computing modules and FPGA development boards also commonly use this connector to route parallel data buses between stacked cards.

Frequently Asked Questions
How many positions does the TFC-136-02-F-D-A-K provide and how are they arranged?
The TFC-136-02-F-D-A-K provides 72 positions arranged in 2 rows at a 0.050" (1.27 mm) pitch. This dual-row configuration allows routing of up to 72 discrete signals in a compact footprint, well suited for parallel bus interfaces and mixed signal applications on industrial and computing boards.
What current rating per contact does the TFC-136-02-F-D-A-K support for power and signal lines?
Each contact of the TFC-136-02-F-D-A-K is rated at 1.0 A continuous current. Designers commonly dedicate several contacts for power and ground rails, with remaining contacts allocated to signal lines, allowing the 72-position connector to serve both power distribution and high-density signal routing within a single mated connector pair.
What design advantage does the Tiger Eye contact geometry offer over standard stamped contacts in cost-sensitive designs?
The Tiger Eye contact geometry is engineered for cost-effectiveness while maintaining reliable low insertion force mating, typically requiring less than 100 grams of force per contact. This reduces connector engagement effort in high-density 72-position assemblies and lowers the risk of PCB pad stress during mating, which is especially valuable in hand-assembled prototypes and field-replaceable boards.
When should an engineer choose TFC-136-02-F-D-A-K over a higher-performance SAMTEC connector for a backplane application?
The TFC-136-02-F-D-A-K is the right choice when signal frequencies remain below approximately 500 MHz and cost is a primary constraint, as the Tiger Eye design trades off high-frequency performance for lower price per position. For backplane signals exceeding 1 GHz or differential pairs needing controlled 100-ohm impedance, upgrading to SAMTEC's high-speed series such as the SEARAY or ExaMAX would be more appropriate.
