What are the key features of TFC-124-02-L-D-A?
- 48-position dual-row layout at 0.050 inch (1.27 mm) pitch delivers high-density signal routing in a minimal PCB footprint
- Tiger Eye bifurcated contact geometry provides dual-point wiping contact for low-resistance and reliable electrical connection across many mating cycles
- Cost-effective terminal strip design offers a budget-friendly alternative to premium mezzanine connectors without sacrificing contact reliability
What is TFC-124-02-L-D-A used for?
The TFC-124-02-L-D-A is used in high-density board-to-board signal interconnects in embedded computing modules, FPGA development boards, and data acquisition systems where 48 digital or analog signals must be routed between stacked PCBs in a compact footprint. Its 0.050 inch pitch dual-row layout provides twice the signal density of standard 0.100 inch pitch single-row connectors, suiting telecommunications interface cards, industrial I/O backplanes, and test-and-measurement front-end boards. The low cost per position makes it attractive for medium- to high-volume production where connector BOM cost is a significant design consideration.

Frequently Asked Questions
How many positions does the TFC-124-02-L-D-A provide, and how does the dual-row layout improve signal density?
The TFC-124-02-L-D-A provides 48 positions in a dual-row configuration at 0.050 inch (1.27 mm) pitch. A dual-row layout at this pitch fits 48 pins in a connector body approximately 30.5 mm long, while a single-row 48-pin connector at the same pitch would be 60 mm long. This nearly 50% length reduction is critical on PCBs where card-edge length is constrained, such as mezzanine cards in 3U or 6U rack systems.
What is the Tiger Eye contact design in SAMTEC TFC series connectors, and what cycle life benefit does it offer?
SAMTEC's Tiger Eye contact uses a bifurcated cantilever beam that provides 2 independent contact points per pin position. During mating, each beam tip wipes the mating contact surface, removing surface oxide layers and ensuring low contact resistance even after repeated insertions. This dual-wipe mechanism is rated for significantly more reliable operation across 100 or more mating cycles compared to single-beam contacts, making it well suited for test fixtures, removable expansion modules, and field-replaceable cards.
How does the TFC-124-02-L-D-A at 0.050 inch pitch compare to 0.100 inch pitch connectors for the same 48-signal interface?
At 0.050 inch (1.27 mm) pitch, the TFC-124-02-L-D-A routes 48 signals in a connector body roughly 30 mm long, while a 0.100 inch pitch 48-pin single-row connector would span approximately 120 mm. The 0.050 inch dual-row design saves approximately 90 mm of PCB card-edge length and reduces the per-signal footprint area by about 60%, which is critical in compact embedded modules, mini-PCIe form-factor boards, and FPGA development cards with limited card width.
Which procurement considerations apply when sourcing TFC-124-02-L-D-A for a 1,000-unit production run?
For a 1,000-unit run, the TFC-124-02-L-D-A's cost-effective design translates to a lower cost per position compared to premium high-cycle SAMTEC alternatives, reducing connector BOM cost by approximately 20% to 40% per unit. Buyers should confirm stock availability since SAMTEC TFC-series terminal strips are stocked in standard quantity breaks at authorized distributors. The YTEOL of 9.4 years indicates the part is in active production, minimizing long-term supply risk for designs expected to remain in production beyond 5 years.
