What are the key features of QTE-040-02-L-D-A-K?
- 80 contacts in 2 rows at 0.8 mm pitch for very high-density board-to-board stacking with minimal PCB real estate
- Gold (10 µin) over nickel (50 µin) contact finish ensures low contact resistance and reliable mating over many insertion cycles
- Phosphor bronze contact material with surface mount termination compatible with standard lead-free reflow assembly processes
What is QTE-040-02-L-D-A-K used for?
The QTE-040-02-L-D-A-K is designed for high-density board stacking in compact consumer electronics, wearable devices, and small form-factor computing modules where 0.8 mm pitch connectors maximize contact count in minimal board space. Its 80-position dual-row layout accommodates wide data buses and mixed signal/power connectivity between stacked PCBs. The gold-plated contact finish ensures stable electrical performance even in low-insertion-force applications with infrequent mating cycles.

Frequently Asked Questions
How many contacts does QTE-040-02-L-D-A-K provide and what is its board stacking pitch?
The QTE-040-02-L-D-A-K provides 80 contacts arranged in 2 rows at a 0.8 mm pitch. This very fine pitch allows 80 signal or power connections in a footprint significantly smaller than 1.27 mm pitch alternatives, making it ideal for compact board stacking in wearable devices, IoT modules, and handheld instruments.
What contact finish does QTE-040-02-L-D-A-K use and why does it matter for reliability?
The QTE-040-02-L-D-A-K uses gold (10 µin) over nickel (50 µin) on mating surfaces and tin over nickel on solder termination tails. Gold plating prevents oxidation and ensures consistent low contact resistance across all 80 positions throughout the connector's service life, which is critical for high-speed digital signals and analog references in sensitive board-stacking applications.
For a portable medical module design, how does QTE-040-02-L-D-A-P's 0.8 mm pitch compare to 1.27 mm alternatives?
At 0.8 mm pitch, the QTE-040-02-L-D-A-K delivers 80 contacts in roughly half the board footprint of a comparable 1.27 mm pitch connector carrying the same contact count. This space saving is decisive in portable medical modules, wearables, and compact IoT gateways where PCB area is at a premium and the 80-position bus width cannot be reduced without sacrificing functionality.
What is the lead time for QTE-040-02-L-D-A-K and how should procurement plan for it?
The QTE-040-02-L-D-A-K has a factory lead time of approximately 2 weeks and 4 days according to distributor data. For production runs, procurement teams should place orders at least 3 weeks in advance to avoid schedule risk. Stocking a buffer of 80-position connectors is advisable when the part is on the critical path for board stacking assembly.
