Key Features
- 86-position dual-row male terminal strip at 0.050 inch pitch supporting high-count signal routing across board-to-board interfaces in a compact footprint
- Tiger Eye cost-effective contact geometry delivering reliable signal connectivity with controlled insertion force across standard assembly and field mating cycles
- Low-profile board connector design optimized for dense PCB layouts in industrial automation, embedded computing, and communications equipment
Applications
The TFC-143-02-L-D-A is designed for high pin-count board-to-board interconnect in FPGA carrier boards, industrial multi-axis controller backplanes, and embedded system expansion interfaces. Its 86-position dual-row layout at 0.050 inch pitch allows engineers to route 86 signals in approximately 2.2 inches of connector length, significantly reducing board edge consumption compared to lower-density alternatives.

Frequently Asked Questions
What signal capacity does TFC-143-02-L-D-A offer, and how does its dual-row pitch compare to standard 0.100 inch pitch connectors?
The TFC-143-02-L-D-A supports 86 positions at 0.050 inch (1.27 mm) pitch in a dual-row layout. Compared to a standard 0.100 inch pitch single-row connector, the TFC-143-02-L-D-A achieves roughly 4 times the signal density per unit length, allowing 86 connections in a connector body approximately 2.2 inches long versus more than 8 inches required at 0.100 inch pitch single-row.
In which high-density PCB applications is TFC-143-02-L-D-A preferred over discrete wire-to-board connectors?
The TFC-143-02-L-D-A is preferred in board-to-board applications such as FPGA expansion modules, industrial backplanes, and high-channel-count data acquisition cards where 86 signals must be transferred reliably without the bulk of individual wire leads. The dual-row 0.050 inch pitch format eliminates wiring harness assembly, reduces connector count, and provides a mechanically stable mating interface suited to vibration-prone industrial environments.
How does specifying TFC-143-02-L-D-A affect procurement planning compared to custom-pitch alternatives?
The TFC-143-02-L-D-A is a standard SAMTEC catalog part at 0.050 inch pitch, available through global distribution with typical short lead times. Custom-pitch alternatives generally require 8-to-16-week lead times and minimum order quantities, while standard catalog connectors like TFC-143-02-L-D-A support low-volume prototyping and high-volume production from the same part number, simplifying supply chain management.
