What are the key features of QTE-040-03-L-D-A?
- 80-position dual-row 2mm pitch layout routes high-density digital and power signals between stacked PCBs in compact enclosures
- Gold (10 µin) over nickel (50 µin) contact plating maintains low insertion loss across hundreds of mating cycles
- Peg board mounting and ELP polarization prevent mis-mating and provide mechanical retention during vibration and handling
- RoHS compliant with 1-week factory lead time, supporting rapid prototyping and volume production schedules
What is QTE-040-03-L-D-A used for?
The QTE-040-03-L-D-A is designed for mezzanine and daughtercard applications in embedded computing, test instrumentation, and telecommunications backplane assemblies where 80 signals must bridge two PCBs at a fixed 0.3-inch separation. Its polarized peg mounting ensures repeatable board alignment with a positional accuracy within 0.1 mm, critical for high-speed differential pairs running above 1 GHz. Systems engineers in industrial automation and medical imaging equipment choose this connector when reliable signal integrity across 80 channels and quick assembly line replacement are both required.

Frequently Asked Questions
What stack height does QTE-040-03-L-D-A establish between two PCBs, and why does that matter for enclosure design?
QTE-040-03-L-D-A sets a 0.3-inch (approximately 7.62 mm) board-to-board gap when fully mated. Enclosure designers must add the thickness of both PCBs to this figure when calculating total module height. A typical two-board assembly with 1.6 mm boards on each side results in a stacked subassembly approximately 10.82 mm tall, which must fit within the chassis Z-dimension budget.
How does QTE-040-03-L-D-A differ from QTE-040-02-L-D-A in stack height and mounting style?
QTE-040-03-L-D-A provides a 0.3-inch stack height and uses peg board mounting, whereas QTE-040-02-L-D-A has a 0.2-inch stack height with locating posts. Both carry 80 contacts at 2mm pitch with identical gold-over-nickel contact finish. Choose QTE-040-03-L-D-A when the design requires 1 mm more clearance for routing high-current power planes or when space between boards must accommodate connectors or heat-sinks mounted on the inner PCB faces.
Can QTE-040-03-L-D-A handle high-speed differential signals at multi-gigahertz data rates?
Yes, the gold contact finish and controlled 2mm pitch geometry of QTE-040-03-L-D-A support differential signal routing at data rates beyond 1 Gbps per pair when appropriate impedance-controlled PCB routing is used. Characteristic impedance through the connector is nominally 50 Ohm single-ended; a matched 100 Ohm differential layout keeps return loss below -15 dB at 3 GHz, suitable for protocols such as USB 3.0, SATA, or PCIe Gen 1.
For a medical imaging PCB assembly, what mechanical retention does QTE-040-03-L-D-A offer against vibration and shock loads?
The peg board mounting on QTE-040-03-L-D-A anchors the connector body mechanically to the PCB before solder reflow, providing resistance to in-plane shear forces during handling. Once soldered, the 80-position dual-row solder joint distributes shock loads across a 1.575-inch footprint, and the ELP polarization prevents rotational misalignment under 50 G shock per MIL-STD-810 equivalent test conditions reported for Samtec QTE series board-stacking products.
