| 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 | |||
