Key Features
- 96-position dual-row terminal strip at 0.050" (1.27 mm) pitch for ultra-high-density board interconnect
- Tiger Eye contact design provides reliable spring-beam mating with consistent insertion and withdrawal forces
- Female metal (FM) contact configuration mates with standard 0.050" pitch male pin headers and test probes
- Tape-and-reel (TR) packaging enables fully automated SMT pick-and-place assembly at high production volumes
- Cost-effective design optimizes BOM economics for high-density multi-board interconnect applications
Applications
The TFC-148-02-FM-D-A-K-TR is ideal for high-density board-to-board and board-to-cable interconnect in FPGA development boards, server blade modules, and high-speed data acquisition systems requiring 96 signal connections at 0.050-inch pitch. Its Tiger Eye spring-beam contacts maintain reliable electrical contact across repeated mating cycles in test and measurement fixtures and automated board handling equipment. The tape-and-reel format supports volume manufacturing in networking equipment, storage arrays, and rack-mount computing platforms.

Frequently Asked Questions
What contact pitch does TFC-148-02-FM-D-A-K-TR use and how does 0.050 inch compare to standard 0.100 inch connectors?
TFC-148-02-FM-D-A-K-TR uses a 0.050-inch (1.27 mm) pitch, which is exactly half the spacing of standard 0.100-inch connectors, allowing 96 positions to fit in the same linear board space that a 48-position 0.100-inch strip would occupy. This density advantage is critical in FPGA and multi-signal interfaces where board real estate is at a premium and routing 96 individual traces must be accomplished within a compact zone.
How does the Tiger Eye contact design in TFC-148-02-FM-D-A-K-TR improve mating reliability compared to conventional socket contacts?
Samtec's Tiger Eye contact uses a dual-beam spring design that makes redundant electrical contact at 2 points on each mating pin, reducing contact resistance to typically below 30 milliohms even after 500 mating cycles. The dual-wipe action also self-clears minor surface contamination, improving reliability in industrial environments where dust or oxidation can degrade single-beam contacts over time.
For which high-speed signal applications is TFC-148-02-FM-D-A-K-TR at 0.050 inch pitch well suited?
At 0.050-inch pitch, TFC-148-02-FM-D-A-K-TR is well suited for differential signal pairs, LVDS buses, and parallel data interfaces operating up to several hundred MHz, as the tight 1.27 mm spacing supports controlled-impedance PCB routing with 50-ohm or 100-ohm differential trace geometries. It is commonly used in FPGA mezzanine cards, memory expansion boards, and high-speed ADC/DAC evaluation platforms.
What production quantity threshold makes tape-and-reel packaging of TFC-148-02-FM-D-A-K-TR most cost-effective?
Tape-and-reel (TR) packaging for TFC-148-02-FM-D-A-K-TR is most economical for production batches of 200 or more units, where automated pick-and-place placement at rates exceeding 2,000 components per hour reduces per-unit labor cost by 80 to 90 percent compared to manual placement. For prototype quantities under 50 units, strip or tray packaging avoids the reel minimum order quantity premium.
