Selection Guide and Suggestions for Domestic Compatibility and Substitution Solutions
When selecting Amphenol Socapex military standard circular cables and connectors, it is recommended to consider the following dimensions:
Application Environment Requirements
Is it necessary to meet specific military specification MIL-DTL standards (such as the 38999 series)?
The ability to withstand extreme environments such as temperature, vibration, and humidity;
2. Electrical and Mechanical Parameters
Contact numbers and pin layout;
Current load and impedance matching;
Connector type (round plug/socket) and locking method selection;
3. Dimension and Weight Constraints
Micro-sizing configurations are prioritized for space-limited devices.
High-density PCB connection scenarios are adapted to special product series.

Three, reference suggestions for domestic compatibility and replacement solutions:
With the rapid development of domestic interconnect technology, more and more enterprises have launched domestic circular connector cable products that meet military specifications such as MIL-DTL-38999. For customers seeking domestic alternatives:
Focus on domestic products with equivalent specification certifications (such as Q/Jxxxx domestic military standards) and mechanical and electrical parameters that are close to those of imported products.
Pay attention to the consistency of shell size, nominal current, pin arrangement, and sealing protection grade with the original brand product when selecting.
If used in critical military or aerospace fields, it is recommended to confirm the reliability test data and usage verification cases with the supplier.
In some general industrial application scenarios, domestic cable components usually have more advantages in terms of cost-performance, delivery cycle, and after-sales service.
By comparing the original Amphenol Socapex product specifications with the specifications of domestic suppliers, a more cost-effective alternative solution can be formulated to enhance the overall supply chain stability of the project.

Amphenol Socapex's military-standard circular cables and connectors have gained wide recognition in the military and high-end industrial markets due to their deep technical accumulation and strict quality control. Whether it is for high-speed data transmission, power transmission under harsh environments, or complex wiring harness requirements, their products can provide stable and reliable interconnection support. With the continuous maturity of domestic substitution technology, for projects that are budget-sensitive or have high requirements for supply chain localization, selecting domestic-compatible products rationally has also become a valuable choice.
We have been committed to the research and development of domestic alternatives for such military specification connectors and cable components, and we have rich selection support and localized product resources.
