- Filters, power connectors, etc. for 5G base stations have basically been domesticated
- High-speed backplane connectors achieve breakthroughs in low- and medium-end speeds (below 10Gbps)
- Data center begins customer verification phase with high-speed connector
- The localization rate of optical module supporting connectors has increased rapidly
- Circular connectors: Industrial circular connectors such as M8/M12 instead of acceleration
- Heavy-duty connectors: some domestic manufacturers have entered the low-end market
- PCB terminal blocks: high domestic substitution rate and fierce competition
- Industrial Ethernet connectors: starting to break through, there is still a big gap
II. Process of Domestic Substitution in Various Application Areas
2.1 Consumer electronics: the most mature field of domestic substitution
Consumer electronics is the field with the highest replacement rate of domestic connectors.In smartphones, TWS headphones, smart wearables and other products, the penetration rate of domestic connectors has been quite high.
Degree of domestic substitution in the consumer electronics field:
The characteristics of domestic substitution in the field of consumer electronics are: wide range, fast iteration speed, sensitive to costs, and rapid penetration by domestic manufacturers with rapid response and cost advantages.At present, the main gap is concentrated in high-end products such as ultra-precision, high-frequency and high-speed.
2.2 Automotive electronics: the largest area of domestic substitution space
The outbreak of new energy vehicles provides a historic opportunity for the domestic replacement of connectors.In traditional fuel vehicles, the connector market is basically monopolized by overseas giants.New energy vehicles have brought a lot of new connector demand, and the supply chain of domestic vehicle manufacturers is more open.

2.3 Communications and Data Centers: The Main Battlefield of High-End Alternatives
Communications and data centers are among the most technology-intensive areas for connectors.High-speed backplane connectors, power supply connectors, optical module connectors and other products have high technical barriers, and have long been monopolized by international giants such as TE and Amphenol.
In recent years, domestic manufacturers have made significant progress in the field of communications:
However, in the field of high-speed backplane connectors above 25Gbps and high-end optical module connectors such as QSFP-DD/OSFP, domestic substitution is still in its infancy, requiring long-term technical accumulation and customer verification.
2.4 Industrial Controls: Alternative Markets for Steady Growth
In the industrial control field, the reliability of the connector is extremely high, the certification cycle is long, and the customer stickiness is strong.Although domestic substitution started late, it has grown significantly in recent years.
Main directions of domestic replacement of industrial connectors:
III. Opportunities for Domestic Substitution
3.1 Huge market space
China is the world’s largest consumer market for connectors, but the market share of local manufacturers is still low.Even if the domestic substitution rate increases by 10 percentage points, the corresponding market size will reach tens of billions of yuan.Especially in high-end fields such as automobiles, industry, and communications, there is more room for domestic substitution.
3.2 Downstream industry synergy
China has the most complete electronics industry chain in the world, and the downstream application industry is developed.The global competitiveness of new energy vehicles, consumer electronics, communication equipment, industrial manufacturing and other industries has been continuously strengthened, providing a good customer base and development environment for upstream connector manufacturers.
3.3 Policy Support
The state attaches great importance to industrial chain and supply chain security, and has issued a series of policies to support the localization of high-end manufacturing, semiconductors, and key components.As a basic component of the electronic information industry, connectors also benefit from the support of relevant policies.
3.4 Technical Iteration Window
Emerging areas such as new energy vehicles, AI servers, and AR/VR have brought new connector technology routes.On these new circuits, the technological gap between domestic and foreign enterprises is relatively small, and domestic manufacturers have the opportunity to achieve corner overtaking.
IV. Challenges of Domestic Substitution
4.1 Technology Gap Remains
Although domestic connectors are making rapid progress, there are still gaps in multiple dimensions compared to the world-class level:
4.2 High Barriers to Customer Certification
The reliability of the connector directly affects the performance of the whole machine, and downstream customers are extremely strict in their certification of suppliers.Especially in the automotive, communications, industrial and other fields, the supplier certification cycle is as long as 2-3 years, and once selected, it will not be easily replaced.Domestic manufacturers need to go through a lengthy verification process to enter the supply chain of high-end customers.
4.3 Lack of brand and trust
After decades or even hundreds of years of accumulation, the international connector giant has built a strong brand influence and customer trust.In contrast, the awareness and trust of domestic connector brands in the high-end market still need to be improved.Customers tend to prefer international brands when choosing high-end connectors.
4.4 High-end materials and equipment rely on imports
The high-end materials involved in the manufacture of connectors (such as special copper alloys, high-performance engineering plastics, high-end electroplating additives, etc.) and high-end equipment (such as precision stamping machines, high-speed automatic assembly machines, etc.) still rely heavily on imports, which to a certain extent restricts the development of domestic connectors.
4.5 Talent Shortage
The research and development of high-end connectors requires multidisciplinary and cross-disciplinary talents such as machinery, materials, electricity, and electromagnetism.At present, the supply of such professionals in China is insufficient, especially senior engineers with rich experience are even more scarce.
