Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

How do I verify whether D38999/26WJ35AA is compatible with my mating connector and shell-size layout?
For D38999/26WJ35AA, start by confirming the Series III shell family, shell size 35, and the insert arrangement 35AA against the mating plug and receptacle callout in your assembly drawing. The key checks are shell size, keying/orientation, contact arrangement, and whether the connector stack-up allows the full coupling and backshell envelope. D38999/26WJ35AA should be treated as a mechanical interface part first: if any of those dimensions differ, the connector may not mate even if the series name looks similar.
Can D38999/26WJ35AA be used in a design that has vibration or repeated mating cycles?
D38999/26WJ35AA is a circular connector format commonly selected for environments that include vibration, but the actual result depends on proper strain relief, harness support, and the mating hardware used around it. In practice, the connector itself is only one part of the retention system. For D38999/26WJ35AA, confirm that the coupling method, cable clamp, and any backshell or overmold reduce cable loading so the contacts are not carrying mechanical stress during vibration or flexing.
What should I check before using D38999/26WJ35AA as a replacement for another MIL-style circular connector?
When replacing an existing part with D38999/26WJ35AA, compare the exact shell size, keyway position, contact layout, panel cutout, and hardware depth rather than relying on the family name alone. Even within similar circular connector lines, small differences in insert arrangement or shell variant can change interchangeability. D38999/26WJ35AA can be a practical substitute only if the mating half, mounting style, and harness termination are matched at the drawing level.
Is D38999/26WJ35AA suitable for long-term industrial equipment, or are there installation details that affect reliability?
D38999/26WJ35AA can be used in long-term equipment when the installation controls corrosion, contamination, and mechanical strain. Reliability is usually driven by contact protection, sealing at the mated interface, correct torque on the coupling hardware, and stable cable support. If the system sees temperature cycling or outdoor exposure, D38999/26WJ35AA should be specified with compatible accessories and a maintenance interval that accounts for connector inspection and cleaning.
How do I decide whether D38999/26WJ35AA is a good choice for a design that may need future service replacement?
D38999/26WJ35AA is a reasonable choice when field service needs a standardized circular interface and the mating part is expected to remain available or controlled in the BOM. For serviceability, check whether technicians can access the coupling nut, whether the rear termination method is repeatable, and whether the harness can be removed without disturbing adjacent wiring. If the assembly will be serviced repeatedly, D38999/26WJ35AA should be paired with clear keying and documented mating parts to avoid field mismatch.
What electrical integration checks are needed before wiring D38999/26WJ35AA into a mixed-signal system?
Before wiring D38999/26WJ35AA into a mixed-signal assembly, map each contact to its signal class and confirm that power, low-level signals, and any shield terminations are separated according to your noise and grounding plan. The connector form factor does not by itself guarantee signal integrity. For D38999/26WJ35AA, the practical checks are pin assignment, return path control, shield bonding strategy, and whether the cable construction supports the intended EMI behavior.
Can D38999/26WJ35AA be used in moisture-prone or outdoor enclosures?
D38999/26WJ35AA is often considered for harsh-environment enclosures, but outdoor suitability depends on the full connector system, including the mating half, cable entry, panel sealing, and accessory selection. If moisture exposure is expected, verify that the mated pair and backshell arrangement preserve ingress resistance after installation and after multiple service cycles. D38999/26WJ35AA should not be assumed to provide enclosure sealing on its own without the correct counterpart and hardware.
What are the main differences to evaluate when comparing D38999/26WJ35AA against an alternative part number from another manufacturer?
When comparing D38999/26WJ35AA with an alternate part from another manufacturer, check mechanical interchangeability, contact arrangement, materials, plating, environmental rating, and accessory compatibility. Two parts can look equivalent in a catalog but differ in how the insert is keyed, how the contacts are terminated, or how the shell interfaces with the panel and backshell. For D38999/26WJ35AA migration planning, the safest approach is to validate mating fit, termination tooling, and any qualification requirements before changing vendors.
What should I consider if D38999/26WJ35AA will be assembled in high volume?
For high-volume builds, D38999/26WJ35AA should be evaluated for termination repeatability, operator access, tooling availability, and inspection ease. Circular connectors that are hand-terminated can introduce variability if the process does not control crimp quality, pin insertion, and backshell assembly. With D38999/26WJ35AA, production risk is usually reduced by using the correct insertion/extraction tools, approved crimps, and a build sequence that prevents pin damage during assembly.
How do I know whether D38999/26WJ35AA is appropriate for a rugged cable harness or if I should choose a different connector style?
D38999/26WJ35AA is appropriate when the design needs a compact circular interface with defined mating hardware and a controlled contact arrangement. If the harness requires frequent blind mating, very high pin count in a small footprint, or unusually low insertion force, another connector style may fit better. For D38999/26WJ35AA, the decision usually comes down to whether the system benefits more from rugged coupling and environmental robustness than from simpler or faster field connection behavior.
