Product Change Notice

Effective Date	Description of Change	Download
09/18/2026	517777 - Equipment/Production Transfer or Rearrangement. PSBU is transferring all Hetero molding (molds & presses) from Lincoln 3104 to Nogales 3105 over the next 30 months. There are approximately 450 molds and 18 presses to transfer. To facilitate this, a series of PCNs will be issued covering group of molds (approx 10 to 25 molds per group) which use the same resin.

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
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
