Key Features
- 88 positions in a dual-row 0.050" (1.27 mm) pitch configuration delivering very high signal density per unit of connector length
- Tiger Eye compliant contact design provides low insertion force and consistent normal force across all 88 mating positions
- Cost-effective terminal strip solution for applications where high pin count is needed without the premium cost of shielded high-speed connectors
Applications
The TFC-144-02-L-D-A is suited for high-density board-to-board interconnects in FPGA module interfaces, embedded computing carrier boards, and multi-bus backplane systems where 88 signal lines must be reliably routed on a 0.050" pitch. Its cost-effective design makes it a practical alternative to premium connectors in applications where signal frequencies do not demand specialized high-speed contact geometry or integrated shielding.

Frequently Asked Questions
How does the TFC-144-02-L-D-A differ from the TFC-144-02-L-D-A-K variant?
The TFC-144-02-L-D-A and TFC-144-02-L-D-A-K both feature 88 positions on a 0.050" (1.27 mm) pitch in a dual-row Tiger Eye layout, but the -K suffix typically denotes a keying peg or polarization feature that prevents incorrect orientation during mating. The non-K variant is used when polarization is handled by other means in the PCB assembly, such as asymmetric board outlines or external guides.
What signal count and pitch does the TFC-144-02-L-D-A provide for high-density board connections?
The TFC-144-02-L-D-A provides 88 total signal positions in 2 rows on a 0.050" (1.27 mm) pitch. This high pin count at a fine pitch enables very dense interconnects, allowing 88 digital, analog, or power signals to be routed between PCBs within a connector footprint roughly 2.2 inches (56 mm) long, making it well-suited for FPGA and embedded computing modules.
For which types of embedded computing designs is the 88-position TFC-144-02-L-D-A most appropriate?
The TFC-144-02-L-D-A is most appropriate for embedded computing module-to-carrier-board designs, FPGA daughter cards, and multi-channel data acquisition boards that need to carry 88 signals on a 0.050" pitch. Systems running parallel bus architectures, such as those with wide data paths of 32 bits or more plus address and control lines, particularly benefit from the connector's high position count.
What are the procurement advantages of choosing a Tiger Eye cost-effective terminal strip over a premium SAMTEC series?
The Tiger Eye cost-effective terminal strip series offers lower per-unit pricing compared to SAMTEC's high-speed or shielded connector families, making it practical for price-sensitive designs where signal frequencies are below a few hundred MHz and EMI shielding is not required. For an 88-position connector, the cost savings per board can be significant at volumes of 500 units or more, helping reduce BOM cost without compromising reliability for standard digital signal applications.
