Electronic component base (ECB) refers to the collection of electronic components used to create corresponding devices. The composition and characteristics of the ECB determine a device's functionality, performance speed, precision, power consumption, dimensions, and reliability.
The electronic component base includes1, for example:
passive elements (filters, power dividers, attenuators);
active elements (amplifiers, generators, voltage-controlled devices);
integrated circuits (microcontrollers, processors, ADCs and DACs).
ECB is used in industrial automation, telecommunications equipment, computing technology, transportation systems, energy, medical and measuring instruments, and consumer electronics. Component requirements depend on the end product's purpose. For computing devices, performance and power consumption are critical; for measuring equipment, accuracy and parameter stability matter most; for industrial automation, reliability and operability under specified conditions are paramount.
The availability of ECB in terms of specifications, price, volumes, and delivery times determines the sustainability of equipment production and maintenance. Consequently, the absence of a critically important component can delay product release, require design rework, and increase production costs.
Transitioning to domestic ECB reduces dependence on external supplies, though differences between components may require circuit and software modifications, as well as repeated testing. Its implementation depends on available nomenclature, quality consistency, serial production readiness and technical support, and adequate supplies of materials, equipment, and design tools.
Russia's electronics industry has its own base for component development and production, including for microwave equipment. For instance, Mikran reports industrial mastery of gallium arsenide monolithic integrated circuit manufacturing technology and offers production of amplifier, switching, and diode circuits for frequencies up to 50 GHz. This confirms the presence of domestic competencies in certain segments of microwave electronics.2.
At the same time, significant dependence on foreign components persists. By the time restrictions were introduced in 2022, key foreign companies were supplying 80–90% of components in certain segments. As a result, supply disruptions led to the complete or partial suspension of a number of local production facilities.
However, increased output of finished Russian equipment does not in itself mean reduced dependence on imported electronic components. Research by A.A. Tresoruk compares the roughly 35% growth in production of computers, electronic and optical products for January–October 2024 with less than 1% growth in semiconductor device output. The author views this as an indirect sign of increased use of imported components. Consequently, when assessing import substitution, it is necessary to separately account for final equipment production and the origin of the components used in it.3.
Key Transition Challenges
One of the main technical challenges of the transition is ensuring compatibility of domestic components with existing circuitry. For microwave equipment, matching the operating frequency range and function is not enough: gain, noise characteristics, impedance matching, and stability must all be considered. It follows that replacing a component may require reworking matching circuits and re-verifying parameters for the entire assembly.4.
Production difficulties are related to ensuring a complete technological cycle. The Electronics Industry Development Strategy approved in 2020 already noted shortages of domestic production and testing equipment, accessibility problems for certain semiconductor materials, epitaxial structures, and computer-aided design tools. Therefore, adopting Russian components requires developing related production facilities and design tools: having one's own chip design does not yet guarantee stable serial production.
Economic and personnel constraints further complicate the transition. The same Strategy identifies small-batch production as an obstacle to profitable manufacturing of new products, and the mismatch between some professional competencies and industry requirements as a personnel problem. For the customer enterprise, the cost of components is supplemented by expenses for design adaptation, prototype manufacturing, and testing. As a result, the feasibility of substitution must be assessed based on total costs and implementation timelines, taking into account production readiness and availability of specialists.
A Practical Example of Microcontroller Replacement
Let's examine replacing the STM32L051K8 with the domestic MIK32 "Amur" K1948VK015 in a device that reads data from sensors and controls relays, actuators, or other mechanisms.
Both controllers operate at frequencies up to 32 MHz, but differ noticeably in architecture and memory capacity.
That's why before replacing it, you need to verify whether the program will fit into the MIK32's memory and whether its performance will be sufficient. If the built-in memory isn't enough, you'll need to add external Flash memory to the board5, 6.
Simply installing the new controller in place of the old one won't work. You'll most likely need to modify the board, since the chips differ in package types, pin configurations, and power requirements. The program will also need to be partially reworked.
After the migration, the device must be tested anew: sensor operation, control signals, response speed, and recovery after power loss all need to be verified.
Thus, replacing STM32 with MIK32 affects more than just the microcontroller itself. It requires reworking the board, the software, and repeating tests. The benefits of switching must therefore be weighed against development costs and component availability.
Implications for manufacturers and customers
For equipment manufacturers, the transition to domestic electronic components may bring increased development and production preparation costs. Adapting circuitry, software, and assembly technology, building prototypes, and repeating tests all require time and specialist involvement. During the transition period, this can raise unit costs and push back delivery schedules. An additional burden comes from the need to maintain multiple product versions and support repairs of previously manufactured equipment.
For customers, the consequences may include changes in procurement prices, delivery times, and equipment servicing terms. If component replacement affects equipment characteristics or interfaces, compatibility with existing systems will need to be verified. At the same time, domestic origin of electronic components does not in itself guarantee improved or reduced reliability: compliance with requirements must be confirmed through testing and operational experience. When procuring equipment, it is therefore important to factor in implementation costs, servicing, and potential downtime over the product's entire service life.
In the long term, adoption of domestic components may make supply and technical support more predictable, while interaction with the manufacturer can simplify equipment customization for specific tasks. However, these advantages depend on stable serial production, component quality, and availability of spare parts for repairs. The practical outcome of the transition is determined by how well the reduction in dependence on external suppliers offsets adoption costs and ensures customer requirements are met.
Possible solutions
The transition to domestic electronic components should be carried out in stages, starting with analysis of components whose supply disruption could halt production. For each, available alternatives, the scope of necessary changes, and total implementation cost should be assessed. It makes sense to first work through the replacement on a pilot unit and small production batch, confirming characteristics through testing. In new designs, modular construction and separation of hardware-dependent code from application algorithms can simplify subsequent component changes.
Reducing the labor intensity of the transition will be aided by development of technical support for domestic electronic components. Component manufacturers need to provide complete documentation, application examples, debugging tools, and information on known limitations. For microwave components, models and S-parameters with measurement conditions specified are especially useful, allowing preliminary assessment of device performance. Joint work between component makers and equipment developers, access to testing laboratories, and engineer training will help identify problems faster and bring solutions to serial application.
The economic sustainability of the transition can be supported by coordinating the needs of multiple customers, standardizing in-demand components, and long-term procurement planning. This will allow manufacturers to plan capacity utilization and production expansion more soundly. Government and industry support should be directed at the entire path from development to serial implementation, including materials, equipment, design tools, and testing. The effectiveness of such measures should be assessed by supply stability, confirmed quality, and the cost of using components in finished equipment.
Conclusion
The transition to domestic electronic components represents a complex engineering and production challenge. Its main difficulties are related to component compatibility, costs of equipment rework and testing, availability of serial products, and stability of technological chains. The microcontroller replacement scenario examined shows that even components similar in function may require substantial adaptation of hardware and software.
A phased replacement approach based on specific product requirements and test results helps mitigate transition risks. Scaling this up requires developing production capacity, materials and design tools, training specialists, and fostering collaboration between electronic component manufacturers and equipment developers. The measure of success becomes the ability to consistently produce and service equipment with the required specifications, acceptable costs, and predictable delivery timelines.
