Key Features
- 84-position dual-row board stacking plug with gold (10 µin) over nickel (50 µin) contact finish for reliable low-resistance mating
- Polarized E.L.P. design with locating posts eliminates mis-mating and ensures precise PCB-to-PCB alignment
- RoHS compliant construction with 1-week factory lead time and broad compatibility with standard board stacking stack heights
Applications
The QTE-042-01-L-D-DP-A is suited for high-density PCB-to-PCB stacking applications in embedded computing, industrial control boards, and communication modules. Its 84-position dual-row layout supports parallel data buses and power distribution between boards. The polarized locating-post design is especially valuable in systems where repeated field replacement of daughter cards must be mistake-proof.

Frequently Asked Questions
How many positions does the QTE-042-01-L-D-DP-A provide and how are they arranged?
The QTE-042-01-L-D-DP-A is an 84-position connector arranged in 2 rows of 42 contacts each, with a 0.5 mm contact pitch, enabling high-density signal and power routing between two parallel PCBs.
What contact plating is used on QTE-042-01-L-D-DP-A and why does it matter for contact resistance?
Contacts are plated with 10 µin of gold over 50 µin of nickel, providing corrosion resistance and stable contact resistance below 20 mΩ even after repeated mating cycles, making it suitable for reliable long-life board stacking assemblies.
Which board-stacking or module integration scenarios benefit most from the polarized locating-post feature of this connector?
Applications such as industrial compute modules, ruggedized embedded systems, and field-replaceable daughter cards benefit most, because the polarized E.L.P. design and locating posts prevent 180° mis-insertion, reducing assembly errors on production lines handling 84-pin connectors.
What are the body dimensions of the QTE-042-01-L-D-DP-A and how do they affect PCB layout?
The body measures 0.235 inch in breadth and 0.168 inch in depth, meaning the connector occupies a compact footprint on the PCB. Designers should reserve at least 0.25 inch clearance around the body for locating posts and adjacent component keep-out zones.
