Key Features
- 86-position dual-row layout at 2.00 mm pitch delivers high pin density for compact board-to-board signal routing
- Rugged PCB socket construction with -VS (vertical through-hole solder) and -K (kinked lead retention) features ensures secure mechanical retention on the PCB
- Tape-and-reel (-TR) packaging supports high-volume automated pick-and-place assembly, reducing per-unit handling cost
Applications
The SQW-143-01-LM-D-VS-K-TR is used in industrial computing modules, FPGA mezzanine cards, and telecom line cards where high-density 86-pin mating to standard 2.00 mm pitch headers is required. Its rugged socket construction and kinked-lead retention keep the connector positively located during wave or reflow soldering. Tape-and-reel packaging makes it suitable for automated assembly in medium-to-high volume production runs.

Frequently Asked Questions
How many positions does the SQW-143-01-LM-D-VS-K-TR provide, and at what pin pitch?
The SQW-143-01-LM-D-VS-K-TR provides 86 positions arranged in a dual-row configuration at a 2.00 mm pitch. This pin count is suited for high-speed mezzanine module interfaces, FPGA daughter cards, or multi-function peripheral boards where 86 independent signal, power, or ground connections are needed in a mechanically compact connector footprint.
What do the -VS and -K suffixes in the SQW-143-01-LM-D-VS-K-TR part number indicate about its termination and retention?
The -VS suffix denotes vertical solder termination through the PCB, providing a strong mechanical anchor with solder fillet on both sides of the board. The -K suffix indicates kinked or formed leads that grip the PCB hole during assembly, preventing the connector from falling out or shifting during soldering. Together these features ensure the 86-pin connector stays precisely aligned through wave or selective solder processes.
For a high-volume FPGA mezzanine card build, what assembly advantages does the -TR (tape-and-reel) variant of the SQW-143-01-LM-D-VS-K-TR offer?
The tape-and-reel (-TR) packaging allows automated pick-and-place machines to feed and place the SQW-143-01-LM-D-VS-K-TR at rates of several thousand units per hour, compared to manual tray-and-tube loading. For production volumes exceeding 500 boards per run, this reduces assembly labor cost by eliminating hand placement. Reel quantities for 2.00 mm pitch connectors typically range from 100 to 500 pieces per reel depending on connector length.
