At AVIA Electronics, we understand that your project timelines depend on component reliability. To support your mission-critical operations, we maintain a proactive inventory strategy specifically optimized for the D38999/20KF11PN and our broader line of high-reliability connectors.
In-Stock (Ready to Ship): The D38999/20KF11PN is currently verified in our central facility. Orders placed for these items are processed and dispatched within 24–48 business hours, ensuring minimal downtime for your production or maintenance schedules.
Factory Lead Time: For large-volume requirements of the D38999/20KF11PN or items currently undergoing replenishment, we provide precise, project-specific lead times. We leverage our direct manufacturing partnerships to secure your allocation, offering transparent tracking from the production line to your facility.
Supply Assurance: We prioritize long-term supply stability for our clients. If you require scheduled deliveries, bulk kitting, or buffer stock of the D38999/20KF11PN for multi-phase projects, our logistics team is ready to coordinate a personalized supply plan aligned with your specific project milestones.
Multiple shell sizes available
The D38999/20KF11PN is part of the extensive MIL-DTL-38999 Series III platform, which is engineered for maximum versatility across complex system architectures. We understand that your designs require consistency; therefore, our connector solutions are available in a comprehensive range of shell sizes to ensure an exact mechanical fit for every application.
Full Spectrum of Sizes: While the D38999/20KF11PN represents a specific configuration, the wider Series III product line is available in shell sizes ranging from 09 to 25. This allows engineers to scale their designs—from compact sensor interfaces to high-density power and data modules—without compromising on reliability.
Universal Interface Standards: Every shell size within this series adheres to the identical triple-start threaded coupling mechanism. This ensures that mating procedures, anti-decoupling protocols, and tooling requirements remain uniform across your entire hardware assembly, simplifying your installation and maintenance processes.
Precision Engineering: Regardless of the shell size chosen, each unit is manufactured to stringent military-grade tolerances. Our components undergo rigorous testing for environmental stress, including high-vibration exposure and extreme temperature cycling, ensuring that your system maintains peak signal integrity across all deployment sizes.
Custom configurations supported
At AVIA Electronics, we recognize that off-the-shelf components may not always meet the unique demands of your high-performance systems. While the D38999/20KF11PN represents our standard high-reliability configuration, we offer extensive support for custom engineering to ensure our products integrate perfectly into your specific design architecture.
Bespoke Pin & Insert Arrangements: If your project requires a non-standard contact layout or a specific mix of power and signal pins, we can facilitate custom insert arrangements that maintain the stringent MIL-DTL-38999 performance standards while meeting your exact electrical needs.
Specialized Plating & Material Options: Beyond the standard stainless steel and passivated finishes, we support custom material selections—including specialized platings for enhanced corrosion resistance, EMI shielding, or weight reduction—to survive the harshest operational theaters.
Modified Shell Geometries: For space-constrained installations, we assist in sourcing or coordinating the manufacture of modified shell geometries, including custom mounting flanges, extended barrels, or integrated backshell configurations that reduce assembly complexity.
Turnkey Kitting & Integration: We offer custom kitting services where we package the D38999/20KF11PN with application-specific accessories—such as heat-shrink boots, protective covers, or custom-terminated cable assemblies—ready for immediate integration into your production line.
Sample Policy & Flexible Order Support
At AVIA Electronics, we provide premium, high-reliability interconnect solutions. To ensure the performance of the D38999/20KF11PN meets your precise engineering requirements, we offer a professional sampling service. We are committed to supporting innovation at every stage of your product lifecycle.
Sample Availability: We provide samples of the D38999/20KF11PN for engineering qualification and prototype testing. As these are high-performance military-grade components, a nominal sample fee applies to cover the material cost and individual handling. This ensures that you receive verified, defect-free parts that are representative of your final production batch.
No Minimum Order Quantity (No MOQ): We believe in supporting innovation regardless of scale. Whether you need a single unit for a critical repair or a small pilot batch for system integration, we operate with no minimum order quantity. You have the flexibility to procure exactly what your current phase requires without the burden of overstocking.
