What are the key features of TFC-149-02-LM-D-A?
- 98-position dual-row design at 1.27 mm pitch provides one of the highest pin-count Tiger Eye terminal strip configurations in the series
- Lead-modified (LM) SMT termination enhances coplanarity and delivers more consistent solder joints across 98 contacts during reflow assembly
- Dual-row (D) layout maximizes signal density per unit board length, ideal for dense bus or multi-rail power connections
- Tiger Eye contact technology combines cost efficiency with reliable mating performance and low contact resistance across service life
What is TFC-149-02-LM-D-A used for?
The TFC-149-02-LM-D-A is suited for very high pin-count PCB-to-PCB, mezzanine, and daughtercard interconnect in embedded computing, industrial automation, and communication infrastructure boards. Its 98-position, 1.27 mm pitch dual-row layout supports wide data buses, parallel interfaces, and multi-signal backplane connections where SMT assembly efficiency and contact density are priorities.

Frequently Asked Questions
What is the total contact count and row arrangement of the TFC-149-02-LM-D-A?
The TFC-149-02-LM-D-A features 98 contacts arranged in 2 rows of 49 contacts each, with a 1.27 mm (0.050") center-to-center pitch. This dual-row, high-density layout is designed for applications that require routing 98 independent signals or power lines within a compact surface mount footprint.
How does the lead-modified (LM) termination improve assembly yield for the TFC-149-02-LM-D-A versus standard FM termination?
Lead-modified (LM) termination uses shaped leads with greater coplanarity tolerance than flat-mount (FM) leads. On a 98-position connector, this reduces the probability of lifted leads and cold solder joints during reflow, particularly on PCBs with slight warpage, improving first-pass yield in high-volume manufacturing of boards with many contact points.
Which high pin-count backplane or computing designs commonly use TFC-149-02-LM-D-A?
This 98-position, 1.27 mm pitch terminal strip is commonly used in embedded CPU module-to-carrier board interfaces, FPGA evaluation and expansion boards, industrial PLC backplanes, and telecom line cards where wide parallel data buses and high channel counts at low cost are needed. Its LM leads support reflow at temperatures up to 260°C for lead-free assembly.
