Key Features
- 38-position dual-row configuration at 0.050" (1.27 mm) pitch for dense PCB signal interconnect
- Gold-plated mating contacts on phosphor bronze deliver low contact resistance and reliable cycle life
- Tiger Eye cost-effective construction reduces per-pin cost versus premium terminal strip alternatives
- Dual-row layout maximizes signal throughput per unit length on space-constrained mezzanine and daughter-card PCBs
Applications
The TFC-119-02-LM-D-A is designed for 38-pin board-to-board and mezzanine interconnect applications in embedded computing modules, industrial controllers, and test and measurement systems. Its dual-row 0.050" pitch layout enables routing of 38 parallel signals through a compact footprint without the cost of premium fine-pitch connectors. The Tiger Eye cost-effective design is well suited for mid- to high-volume production runs where cost per signal channel is a key specification.

Frequently Asked Questions
What is the signal capacity and pitch of the TFC-119-02-LM-D-A connector?
The TFC-119-02-LM-D-A supports 38 positions in a dual-row (2-row) arrangement at a 0.050" (1.27 mm) pitch. This configuration provides a high signal density per unit board length and is suitable for mezzanine, daughter-card, and board-to-board interconnect applications in embedded and industrial designs.
For a compact industrial controller with 38 parallel I/O signals, how does TFC-119-02-LM-D-A help minimize board footprint?
By routing 38 signals through a single dual-row connector at 1.27 mm pitch, the TFC-119-02-LM-D-A consolidates what would otherwise require multiple smaller connectors, reducing total connector PCB area and simplifying signal routing on the board. This is particularly valuable in compact industrial controller designs where PCB space is at a premium and signal integrity across 38 lines must be maintained.
How does the TFC-119-02-LM-D-A's gold contact plating benefit long-term field performance?
The gold-plated mating contacts on the TFC-119-02-LM-D-A provide corrosion resistance and maintain low contact resistance, typically below 20 milliohms, throughout the connector's rated mating cycle life. This is especially important in industrial or field-deployed embedded systems that undergo periodic board swaps or maintenance operations involving repeated connector mating and unmating.
Is TFC-119-02-LM-D-A an economical alternative to the SAMTEC SFM series for 38-pin dual-row 1.27 mm pitch applications?
Yes, the Tiger Eye TFC series, including TFC-119-02-LM-D-A, is specifically positioned as a cost-effective alternative to higher-specification SAMTEC series like SFM for the same 0.050" (1.27 mm) pitch and dual-row count. Where SFM series targets higher cycle counts and tighter specifications, the Tiger Eye variant suits applications with moderate reliability requirements, delivering competitive performance at a lower unit cost for 38-pin 1.27 mm pitch interconnect needs.
