Frequently Asked Questions
How many positions does QTE-040-02-F-D-A-K support, and how are they distributed across the connector?
QTE-040-02-F-D-A-K supports 40 total positions arranged in a dual-row layout with 20 positions per row. This configuration provides sufficient contact density to route 40 independent signals or a mix of signals and power lines between two stacked PCBs without requiring multiple smaller connectors.
What contact termination finish does QTE-040-02-F-D-A-K use, and how does it affect solderability?
QTE-040-02-F-D-A-K uses a tin (Sn) finish with a nickel (Ni) barrier on the termination contacts. The nickel barrier prevents tin diffusion into the contact base material, maintaining solder joint integrity over time. Tin termination is compatible with standard lead-free SAC305 solder paste and reflow processes used in RoHS-compliant SMT assembly.
What is the typical lead time for QTE-040-02-F-D-A-K, and when should procurement be planned?
QTE-040-02-F-D-A-K has a factory standard lead time of approximately 2 weeks and 4 days. Designers should account for this lead time when planning prototype builds or early production runs. For high-volume orders or projects with tight schedules, placing orders 3 to 4 weeks before the required delivery date is advisable to buffer against queue variation.
