What are the key features of SQW-147-01-L-D-VS-K-TR?
- 94-position dual-row PCB socket on 2.00 mm pitch providing cost-effective high-density board-to-board connectivity in a compact footprint
- Vertical surface mount (VS) termination with keying (K) feature preventing mis-mating and enabling reliable field assembly in rugged environments
- Visual solder inspection (VS) and tape-and-reel (TR) packaging supporting automated assembly with post-reflow solder joint quality verification
What is SQW-147-01-L-D-VS-K-TR used for?
The SQW-147-01-L-D-VS-K-TR is designed for rugged embedded computing boards, industrial backplane sockets, and module-to-carrier interface connectors requiring 94-position dual-row connectivity on a 2.00 mm pitch. Its keyed shroud prevents mis-mating in field-replaceable module systems, while the visual solder feature allows post-reflow inspection of all 94 solder joints without X-ray equipment. The tape-and-reel packaging and SMT termination support high-volume automated PCB assembly in telecommunications, defense electronics, and industrial control platforms.

Frequently Asked Questions
How does the 2.00 mm pitch of the SQW-147-01-L-D-VS-K-TR reduce PCB footprint compared to a 2.54 mm alternative for the same 94-position count?
Moving from a 2.54 mm to a 2.00 mm pitch across 94 positions in a dual-row layout reduces the connector row length by approximately 21%, from about 120 mm to 95 mm for a 47-position row. This frees roughly 25 mm of board length per row, which is significant on constrained backplane or module cards where connector real estate competes with component placement, routing, and thermal management zones.
What does the visual solder (VS) feature of the SQW-147-01-L-D-VS-K-TR enable during PCB manufacturing quality control?
The VS (visual solder) designation means the SQW-147-01-L-D-VS-K-TR is designed so that all 94 solder joints are accessible for optical inspection after reflow. This allows standard automated optical inspection (AOI) systems to verify solder quality across all contacts without requiring X-ray analysis, reducing inspection cycle time and cost per board. It is particularly valuable in IPC Class 2 or Class 3 production where 100% solder joint verification is required.
In which application categories does the SQW-147-01-L-D-VS-K-TR outperform a standard unkeyed socket for module swap scenarios?
The K (keyed) shroud of the SQW-147-01-L-D-VS-K-TR physically prevents incorrect module insertion in field-replaceable unit (FRU) systems such as industrial I/O modules, rugged computing blades, and telecom line cards. Without keying, a 94-position dual-row socket at 2.00 mm pitch could accept a reversed or offset mating header, damaging up to 94 pins simultaneously. The keying feature eliminates this risk, reducing field service errors and protecting both the PCB and the mating module from irreversible damage.
