Product Change Notice
| Effective Date | Description of Change | Download |
|---|---|---|
| 04/10/2023 | 512712 - Capacity change or tool replacement. This notice is to inform you that Molex Lincoln Nebraska is adding replacement tooling that will affect the product listed. New tooling will be exact replica of current tooling. There will be no change to the product Fit, Form, Function or Appearance when compared to current tooling. Current tooling will be taken out of service once new tooling is qualified. | Download |
| 01/17/2023 | 512182 - Capacity change or tool replacement. Parts listed on this PCN can be assembled and shipped to all customers from Nogales or Shanghai. | 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 |
| 08/06/2021 | 510546 - Packaging Method/Quantity Changing. Due to DU discrepancy between MFG Plant and SCH, DU needs to be adapted to MFG Plant. DU change Only. | 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 |
