Key Features
- 98-position dual-row Tiger Eye contact system at 0.050 inch pitch offering cost-effective high-density PCB interconnection
- Polarization key (K suffix) preventing incorrect mating orientation across all 98 positions in automated assembly environments
- Tape-and-reel (TR) packaging enabling automated SMT pick-and-place at high production volumes with standard feeder equipment
Applications
The TFC-149-02-L-D-A-K-TR is used in cost-sensitive high-density board-to-board interconnect designs for industrial controls, consumer electronics, and embedded computing platforms requiring 98-pin dual-row sockets at 0.050 inch pitch. Its Tiger Eye contact design reduces material cost while maintaining the mechanical retention and signal integrity needed for daughter card and mezzanine module interfaces.

Frequently Asked Questions
What distinguishes the Tiger Eye contact design in the TFC-149-02-L-D-A-K-TR from standard gold-plated SFM sockets?
The Tiger Eye contact system uses a proprietary stamped beam geometry that achieves reliable wiping contact at lower material cost than full gold-plated alternatives, making the TFC series suitable for cost-sensitive applications where hundreds of mating cycles are needed but the budget does not justify premium gold plating across all 98 positions at 0.050 inch pitch.
For a 98-pin dual-row design at 0.050 inch pitch, how does the TFC-149-02-L-D-A-K-TR compare in board area to a 0.100 inch pitch alternative?
A 98-position dual-row connector at 0.050 inch pitch occupies roughly 25% of the PCB footprint of an equivalent 0.100 inch pitch version. For 98 pins at 0.050 inch, the mated length along the row is approximately 49 x 1.27 mm = 62 mm, whereas a 0.100 inch pitch equivalent would span 124 mm, freeing significant board space for other components in compact designs.
Can the TFC-149-02-L-D-A-K-TR be used as a lower-cost substitute for the SFM-149 series in a new design?
Yes, the TFC-149-02-L-D-A-K-TR is designed as a cost-effective alternative to the SFM-149 series sharing the same 98-position dual-row, 0.050 inch pitch footprint. Designers should verify that the Tiger Eye contact's specified insertion force, mating cycle rating, and current capacity per pin (typically 0.5 A to 1 A at the 0.050 inch pitch) meet their application requirements before substituting.
