Key Features
- 40-position dual-row board-stacking connector with phosphor bronze contacts and 10 µin gold-over-50 µin nickel finish for low and stable contact resistance
- Surface-mount termination with tin-over-nickel barrier on the PCB side ensures robust solder joint integrity through thermal cycling and mechanical stress
- Compatible Samtec QTE/QTH stacking system enables precise board-to-board pitch control in rugged embedded computing and industrial module stacks
Applications
The QTE-040-01-L-D-A-K is used in board stacking applications for industrial control modules, embedded SBC carrier boards, and communications mezzanine assemblies where a 40-signal dual-row interface is required between vertically stacked PCBs. The gold-plated contact finish maintains reliable connections in high-vibration environments such as aerospace and defense electronics. Designers specify this connector when combining power and signal lines within a single compact 40-position interface to minimize inter-board cabling.

Frequently Asked Questions
What is the contact finish specification for the QTE-040-01-L-D-A-K and why does it matter for mating reliability?
The QTE-040-01-L-D-A-K uses 10 µin gold over 50 µin nickel on the mating contact surfaces, and tin with a nickel barrier on the PCB termination side. Gold plating ensures low and stable contact resistance, typically below 20 mΩ, across the rated mating cycles. The nickel barrier prevents tin migration from the solder termination from reaching the mating zone, which would otherwise increase contact resistance over time in thermal cycling environments.
For a stacked PCB assembly with 40 signals, when would the QTE-040-01-L-D-A-K be preferred over a wire-to-board solution?
The QTE-040-01-L-D-A-K is preferred over wire-to-board solutions when the design requires fixed board-to-board spacing, a fully solderable surface-mount assembly without manual wiring steps, and a compact footprint routing 40 signals in a dual-row layout. Board-stacking connectors also withstand vibration better than flying leads, making them the correct choice for industrial and embedded computing applications running in environments with up to 10 g vibration loads.
Does the QTE-040-01-L-D-A-K mate with the QTH header series and what stacking height does this combination achieve?
The QTE-040-01-L-D-A-K is designed to mate with Samtec QTH series headers, which are available in multiple stacking heights typically ranging from 4 mm to 23 mm. The specific stacking height in a QTE/QTH combination is determined by the QTH header variant selected, allowing designers to set precise 5 mm, 8 mm, or 11 mm inter-board gaps to accommodate components on the mating board surface.
