| 08/26/2025 | PCN-25-241132 - Manufacturing location change. Please disregard this PCN if you have approved the in-sourcing of plating mentioned on PCNs: PCN-24-209111 PCN-24-209132 PCN-24-212252 PCN-24-212258 PCN-24-215669 PCN-24-215675 PCN-24-216328* We are transitioning the plating of the contacts used in our connectors to in-house production at our Adelberg facility. This change aims to enhance the reliability and flexibility of our supply chain. We will move forward with a fast-track production release for the metal contacts used as components in our connectors. The in-house plating have confirmed technical feasibility via sample trials or previous series production releases. The new plating facility will perform the standard control and quality measures on individual production batches, which are obligatory to comply with our internal series production and product specifications. These measures will include: Thickness measurements Optical and adhesion tests Minor optical differences may be possible due to different tooling. All other process steps during the manufacturing of our products will remain according to our existing releases. The alternative plating supply chain does not change the fit, form, or function of the product but implies a manufacturing location change. | Download | |||
| 06/01/2025 | PCN-24-229991 - Purchase or Supplier Change. we want to inform you, that for our connectors with part numbers listed below, we will expand the supply chain of the raw material of contacts, shieldings and solder clips to a second raw material supplier. The serial production shall start in June 2025. The second source material will be operated without part number change, will increase reliability of supply chain and has no impact on form, fit or function of these products. Internal product and process approval process will be performed. The expansion to a secound source enables TE to increase the flexibility and reliability of the supply chain. | Download | |||
| 07/01/2024 | De-23-010-0715 - Production Location Change. with this product change notification, we want to inform you, that for our connectors listed below under part numbers we will expand the supply chain of the plated contacts by insourcing this manufacturing process into our new inhouse plating facility in Adelberg in addition to our current plating suppliers. The internal serial production shall start in July / November 2024. Affected Article Numbers and effective date you can find in the table below. The insourcing will be operated without part number change, will increase reliability of supply chain, and has no impact on form, fit or function of these products. Internal product and process approval process will be performed. | Download | |||
