Dear Valued Customer:

Mini-Circuits makes every effort to maintain the life of our products to exceed the customer's system life. Product continuity is part of our commitment to quality, reliability and outstanding customer support. However, in cases beyond our control, product change or End of Life is unavoidable, whether it be due to changes in our supply chain and/or other factors. JESD46 and JESD48 are the guiding standards for our PCN (Product Change Notification) and EOL (End of Life) policies.

Mini-Circuits company policy is to maintain products for as long as possible and to use EOL as a last option. We are still manufacturing and selling products that were introduced more than 50 years ago. Similarly, our policy is to avoid changes to fit, form and function that would require PCN notification. Often, changes in supplied materials can be absorbed in our products by adjustments to internal design or manufacturing. We issue PCN's when such shifts within specified parameters cannot be accommodated.

Timing of PCN notifications is based on several factors, including when we receive such notice from our suppliers, when we detect a shift and our current stock situation. There are times that we can provide notification months in advance of the change, but there are also situations that arise because of conditions outside our control.

We understand the impact of change on customers, and as such we take change management of any of our products very seriously. We treat our customers' need for advance notification with the highest importance and realize the attention to detail required in managing any such change. We have structured our internal processes around these needs. Special part numbers (non-catalog items developed to unique customer requirements) may be advised at the time we receive a request for quote for these models. This permits us to review and advise if the PCN change has any impact on the requirement(s) that make these models special part numbers and to ensure all affected models on a tabulated customer drawing are advised at the same time.

Whenever possible, Mini-Circuits will provide compatible replacement parts and guides to support system continuity. We will notify customers of the new part number and/or data and information about lead time for qualification and production units.

Mini-Circuits maintains worldwide manufacturing and test facilities qualified by Mini-Circuits as part of our Disaster Recovery and Business Continuity Programs. Products may be manufactured, fabricated, assembled, or tested at any such facilities without change notification.

Your Account Manager is your primary point of contact for any questions regarding End of Life and product change. Alternatively, you may contact PCN@minicircuits.com. Additionally, our quality and product teams are available to support you and your organization with any concerns or challenges that arise due to End of Life or product change.
