|---|---|---|---|---|---|
| 02/28/2027 | 518442 - Production Transfer. PSBU is transferring all Hetero molding ( molds & presses) from Lincoln 3104 to Nogales 3105. There are approximately 450 molds and 18 presses to transfer. To facilitate this, a series of PCNs will be issued covering group of molds which use the same resin. | Download | |||
| 08/17/2022 | 511610 - Change to product. currently vertical header housings have drain hole and non-drain hole version housing. the drain holes are no longer needed they were used in the past when PCB boards were being washed and are no longer needed. therefore we are eliminating the drain hole option going forward | Download | |||
| 07/18/2022 | 510809 - Change to product. current vertical header housings have a drain hole and non-drain hole version housing the drain holes are no longer needed (they were used in the past when PCB boards were being washed and are no longer needed) therefore we are eliminating the drain hole option going forward | Download | |||
| 02/14/2022 | 511607 - Retraction of PCN 510948. This PCN is a retraction/ recall of PCN 510809 communicated on 1/18/22 for "current vertical header housings have a drain hole and non-drain hole version housing the drain holes are no longer needed (they were used in the past when PCB boards were being washed and are no longer needed) therefore we are eliminating the drain hole option going forward." the reason for retraction is that part numbers that did not contain the drain hole option were included in the impacted parts list used to create pcn 510809 a new pcn will be created and customers will be notified | Download | |||
| 12/31/2020 | 508352 - Supplier Change. actual molex tray supplier will close operations, molex is working getting new try supplier. | Download | |||
| 02/14/2019 | 506400 - Packaging Method/Quantity Changing. This letter is to inform you that the part(s) referenced in this notice will undergo packaging specification changes that may include new container sizes, quantities or changes to the label. No changes will be made to the product as a result of this change. | Download | |||
| 12/24/2018 | 506262 - Capacity Change or Tool Replacement. This letter is to inform you that another set of tooling is being added to meet the current and future demands of this product. There will be no changes in the fit, form or function from the additional tooling when compared to the current tooling. | Download | |||
| 02/01/2016 | GCM 10708360 - Supplier Change. Molex will be changing the pre-plated flat stock, and adding an additional supplier. This change only affects parts made in Lincoln (3104) and Nogales (3105). The current pre-plated flat stock will change from bright tin over copper to reflowed tin over copper plating. In addition, we will also be changing the post plated terminal used in the 5566, 30069, & 43588 vertical headers to the same pre-plated reflowed tin over copper plating. If post plated headers are desired, alternative part numbers are available with matte tin over nickel plating. | Download | |||
