Applications
The QSE-020-01-H-D-A-K-TR is a 40-position dual-row board stacking socket used in mezzanine module interconnects, FPGA daughter card interfaces, and embedded computing stack architectures where precise PCB-to-PCB alignment and reliable signal continuity across 40 pins are required. The positioning pin mounting feature ensures accurate connector-to-PCB placement during automated assembly and prevents mechanical misalignment during mating, making it suitable for compact stacked board assemblies in industrial control systems and communication modules. Tape and reel packaging supports high-throughput automated production of densely populated PCBs with multiple stacking connector sites.

Frequently Asked Questions
How many positions does the QSE-020-01-H-D-A-K-TR have and how does the positioning pin benefit PCB assembly?
The QSE-020-01-H-D-A-K-TR is a 40-position dual-row board stacking socket with 20 pins per row. The positioning pin (PEG) mounting feature inserts into a PCB hole to mechanically fix the connector during reflow soldering and mating, preventing rotation or misalignment across the 0.285 inch body breadth. This improves assembly consistency and ensures all 40 contacts align precisely with mating connector pads.
What body dimensions does the QSE-020-01-H-D-A-K-TR have, and how does it fit into space-constrained board stacking designs?
The QSE-020-01-H-D-A-K-TR measures 0.837 inch in body length, 0.285 inch in breadth, and 0.128 inch in depth, providing a compact SMT footprint for 40-position dual-row board stacking. This slim profile is well suited for low-profile stacked board assemblies where the vertical clearance between PCBs is limited and a high pin count of 40 positions must be accommodated within a narrow connector body.
Is the QSE-020-01-H-D-A-K-TR RoHS compliant, and what lead-time should buyers expect?
Yes, the QSE-020-01-H-D-A-K-TR is PbFree (lead-free) and RoHS compliant, meeting international environmental requirements for electronic components. The factory lead time is listed as 1 week, making it suitable for production schedules requiring relatively fast replenishment of 40-position board stacking sockets. Stock availability and tape and reel packaging further support high-volume procurement planning.
Which board stacking applications are best served by the QSE-020-01-H-D-A-K-TR socket connector?
FPGA mezzanine cards, sensor fusion modules, industrial embedded compute stacks, and communication daughter boards requiring 40-pin dual-row board-to-board interconnects benefit most from this connector. The positioning pin ensures reliable co-planarity between stacked PCBs, while the 0.837 inch body length accommodates 40 contacts in a standard dual-row layout supporting simultaneous signal, power, and control connections across stacked board assemblies.
