This is a cross-reference specialized in alternative products from Japanese manufacturers! We propose interchangeable equivalents that can be used for various environmental investigations and failure analysis.

We have received many inquiries about alternatives for connectors that have been discontinued, as well as requests for replacements. Among these, we have created a cross-reference specifically focused on Japanese manufacturers, which has been a common topic of consultation. For replacements from overseas manufacturers, we can typically address concerns such as failure analysis and environmental documentation within 2 to 3 weeks. We can provide stable supply with a standard delivery time of about 2 to 3 months. Additionally, we can check the availability of part numbers that are not listed in the cross-reference table, so please feel free to contact us!

The development of electronics has given people great dreams and has turned those dreams into reality, one by one. This development has been passed on to the 21st century, inspiring even greater dreams and hopes. I am deeply grateful and delighted to have been able to engage in work that contributes to this segment of the electronics industry. Moving forward, I will continue to serve as a conduit for the appropriate information on semiconductors and electronic components, so that I can help realize humanity's great dreams and support the product and information development of our clients. I am committed to walking alongside our clients and growing together in the information society of the 21st century. However, on the other hand, global environmental issues have become increasingly prominent. As a member of society, I feel the importance of leaving a rich natural environment for the future and preserving the fundamental value of humanity. I am determined to strive towards becoming a company that harmonizes with nature and society as we move towards an endless future.
