The customer faced a situation where the ICs and semiconductors in use became obsolete, making it urgent to consider alternatives. Additionally, due to changes in equipment specifications, the number of modifications needed on the circuit board increased. Furthermore, due to constraints of the equipment casing, it was not possible to change the existing board size, shape, or connector positions, necessitating a redesign that could accommodate all requirements while maintaining the conventional design. Our company carefully selected alternative components with equivalent basic functions, pin configurations, and sizes, and conducted a redesign of the circuit board patterns as needed. We eliminated unnecessary circuits and minimized changes to component placement and wiring patterns, allowing us to conduct integration verification into the equipment while maintaining the existing specifications. This ensured reliable operation checks for both the circuit board alone and the entire equipment, facilitating a smooth transition to mass production and stable supply. To the design team, procurement, and production management—please utilize our replacement design case studies as an optimal solution to enhance operational efficiency, product quality, and reliability in response to obsolete IC measures and specification changes.

The customer faced a situation where the LED they were using was discontinued, making it impossible to procure the necessary components for the existing products. They could not change the size or shape of the circuit board to fit the existing housing, and it was essential to maintain specifications such as LED brightness, emission patterns, and color. While continuing the mass production system, there was an urgent need for the introduction of alternative products to maintain the current product quality. Our company carefully selected alternative LED components with equivalent circuit board sizes and pin configurations, implementing a design replacement that minimized changes to the existing circuit board pattern. After confirming with the customer that the specifications of the LED remained the same through prototype circuit boards, we transitioned to mass production of the final product. This resolved the component procurement risk, achieved a stable production system and quality maintenance, and further reduced overall costs. We encourage design engineers and procurement and production management teams to consider our case as a reference for measures aimed at ensuring stable supply and improving product quality. Please feel free to contact us!

By adopting overseas microcontrollers and FPGAs, we have implemented alternative board designs that achieve stable supply and high performance for customers facing increased component procurement risks due to changes in the global situation. While maintaining the conventional configuration, we have replaced it with a high-functionality microcontroller from a domestic manufacturer, eliminating the need for complex circuit designs and FPGA circuits. This allows us to break free from dependence on overseas components and significantly reduce component supply risks. Furthermore, by simplifying design changes and management burdens, we have achieved improved productivity and reduced total costs. We have realized stable supply to end users while enhancing product safety and market competitiveness through a consistent development process. Design engineers, procurement, and production management can solve on-site challenges and improve operational efficiency through our replacement design examples. Please feel free to contact us!

Due to the discontinuation of the timer IC and level display IC, it has become urgent for customers to switch to alternative products before running out of stock. However, suitable components could not be found from domestic and international manufacturers, making it difficult to maintain the functionality of existing products. In response, our company proposed a new approach to integrate the more than ten existing circuit board versions, which varied according to battery voltage and capacity, into a single version controlled by a microcontroller. This made it easier to switch settings for each model using a rotary switch on the circuit board, eliminating the need for volume adjustments during inspection, while also successfully reducing costs in circuit board management and inspection processes. As a result, we were able to respond flexibly to the issue of alternative parts, ensuring stable product supply and overall cost reduction. We encourage design engineers, procurement, and production management to consider this case as a reference for measures against component obsolescence risks and for improving operational efficiency.

With the expansion of the lineup of currency exchange machines, it became necessary to convert the existing RS232C signals to RS422 signals. However, due to constraints in the device housing, changing the board size was not possible. Therefore, we faced the challenge of improving signal conversion performance while maintaining the existing design by adding an RS422 conversion circuit to the current RS232C board. Our company first conducted detailed hearings with customers to optimize the circuit of the existing board, and then, after confirming the operation with a prototype RS422 conversion board, established a design that could be integrated without changing the board size. Furthermore, in addition to evaluating the board alone, we conducted verification of its incorporation into the device and confirmed that there were no issues with all specified operations. This enabled us to achieve the continued use of the existing design and high-reliability signal conversion, responding to the expansion of the currency exchange machine lineup. We would like design engineers, procurement, and production management to consider this case as an optimal solution that enhances product performance, production stability, and cost efficiency while overcoming the constraints of the device housing.
