| 05/31/2025 | 516224 - Capacity change or tool replacement. This notification is to inform you about Molex will expand production capacity on 4 circuit sizes of receptacle. | Download |
| 07/12/2022 | 512278 - Retraction of PCN 510384. Due to global material constraints & delays on getting this material to move. | Download |
| 03/10/2022 | 511516 - Change Supplier. PCN is to modify 510147 Molex resin supplier is having raw material & capacity issues on an additional mater to avoid a line down situation at molex and molexs customers Molex Lincoln USA and Molex Chengdu China must purchase resin globally from the current resin supplier change would allow resin to be purchased from multiple locations: Florence Kentucky USA Evansville Indiana USA Nanjing China all remaining info conforms with PCN 510147. | Download |
| 08/16/2021 | 510384 - Supplier Change. Due to mfg constraints at the Florence Kentucky Location of one of our resin suppliers it has been determined to move the Mfg of one of the resin product families to Evansville Indiana location of that same supplier. | Download |
| 02/22/2021 | 509748 - Capacity change or tool replacement. Due to OEM increase in product we are experiencing extremely high demand beyond our capacity to respond within lead time. molex is expediting capacity component tooling to increase output.

| 08/01/2014 | GCM 10627818 - Supplier Change. | Download |
| 07/31/2013 | The purpose of this letter is to inform you that Molex will be updating the design of our Mini50 4, 8, and 12-way headers and receptacle connectors. Molex was chosen as the USCAR interface for 0.5mm connection systems, with some design improvements from our current model to improve the anti-scooping features. These changes will improve performance of the connection system. The attached presentation shows all changes to each circuit size. The changes will specifically affect the interface of the 8-way and 12-way connectors. The older versions will be obsolete and will not able to be used with the UPDATED versions. We are in process of updating the tooling and kicking off new tools that will adapt these changes. All new updated and new tooling with be produced and shipped from our plant in Chengdu, China. We are keeping the same part numbers for 4 and 8way headers and connectors. For the 12-way we have pulled new part numbers and will OBSOLETE the old part numbers. | Download |
