Risk control key points for the bulk purchase of domestic DDK/Fujikura circular connectors

DDK (now Fujikura Connector Business Unit) is a well-known connector brand under the Japanese Fujikura Group, covering high-precision electronic connector products such as RF/microwave coaxial connectors (such as PSH and PSH2 series), FPC/FFC connectors (such as FF10S and FF57 series), circular connectors (compatible with MIL-DTL-5015 D/MS series), board-to-board and stack connectors (FB series), etc. Its products are widely used in professional fields such as broadcasting, wireless communication, automotive, medical, and defense.

Domestic substitution demand and procurement risks
With the rapid development of the domestic electronics manufacturing industry, the replacement of domestic connectors for DDK/Fujikura brands has become a trend, but it is necessary to control the following key contract risks during the bulk procurement process:
Risk of quality consistency
●DDK/Fujikura connectors are manufactured using strict automated production processes, ensuring stable product quality and high precision; domestically produced substitute products must also ensure high consistency, otherwise, bulk purchases may lead to serious consequences such as rework, scrapping, and production line stoppages due to high rates of defective products.
2. Technical specifications and compatibility risks
●DDK's RF, FPC, circular connectors, etc., have high requirements for parameters such as size, contact force, and durability; the contract should clearly specify the key parameters of domestic substitute products, and set up a third-party laboratory or incoming material inspection to ensure performance alignment.
Supply stability risk
Domestic manufacturers must have the ability to maintain continuous supply. The contract should clearly stipulate terms such as delivery schedules, inventory requirements, and emergency supply mechanisms to avoid disruptions in the production rhythm due to shortages in any link.
Intellectual property rights and compliance risks
Avoid infringement of DDK/Fujikura's patents or designs. The contract requires that domestic substitute products be independently designed or legally authorized, and provide corresponding proof documents.
5. Risk of Acceptance and After-sales Support

●It is recommended to set up a phased acceptance, sample confirmation, and repair or replacement mechanism in the contract, and clearly define the warranty period and scope of responsibility, in order to respond quickly to problems after they occur.

Contract Terms Suggestions (Briefly)

Risk control practice examples

For example, when purchasing D/MS series circular connectors (compatible with MIL-DTL-5015, with 12 shell sizes and a rich variety of pin combinations), samples and the MIL-DTL-5015 specification book can be attached to the contract, and insulation withstand voltage, insertion-extraction life, environmental aging tests, etc. can be carried out by a third-party laboratory; and it is required that the domestic substitute products in subsequent batches have consistent performance with the samples. If the test is不合格, the right to require a return or compensation is reserved.

By clearly identifying potential risks such as quality, technology, delivery time, and intellectual property rights in the domestic connector replacing DDK/Fujikura products, and clearly defining corresponding clauses and guarantee mechanisms in bulk procurement contracts, enterprises can effectively control risks, ensure production continuity and product reliability, and lay a solid foundation for domestic substitution cooperation. A sound contract strategy is the guarantee for efficient cooperation and a win-win situation.
