Molex Stac64™ Automotive Connection System

The Molex Stac64™ Automotive Connection System is a 2.54mm (.100") Pitch, stackable connection system offering a diverse range of circuit sizes. Requiring no custom tooling, the Stac64 system allows OEM and device manufacturers greater design flexibility to support both low-level signal requirements as well as power applications upwards of 30.0A. The Molex STAC64 Automotive Connection System also allows automotive manufacturers to use header assemblies as stand-alone components, to gang multiple headers together to support a large range of signal and power needs for devices and modules.

The Molex Stac64 is a standard product system based on USCAR-2 Class II mechanical and electrical performance characteristics for unsealed connector applications. The connectors mate to existing wire-harness connectors designed to the USCAR/EWCAP industry footprints.

Features
Applications
  • Stackable connection system of readily available PCB headers ensure reduced time-to-market: engineering and validation times reduced significantly; no tooling necessary to produce custom multi-bay headers
  • The header and female receptacle housings are molded in standard USCAR color schemes for visual polarization and to aid in connection system assembly
  • Pre-assembled, linear Mylar PC tail alignment strip for right-angle headers reduces PCB packaging complexity and provides space savings
  • Modular-housing design with standard dovetail features molded into the housings allows headers to be ganged together in large assemblies to meet growing terminal quantity requirements
  • PCB alignment posts ensure all terminals are properly aligned into PCB through-holes during assembly and retain header to PCB during assembly and solder processing
  • PCB stand-offs molded into housings provide an additional trace-routing area under the headers
  • High-temperature thermoplastic housings withstand infra red (IR) and wave lead-free solder processing per ES-40000-5013 Molex specification, maximum temperature +260°C
  • Female receptacle TPA release latches greatly reduce the possibility of seating TPA’s during transit and handling plus they require no tools for service
  • Pre-assembled TPA-to-receptacle housing shipped as single assembly provide applied assembly labor and cost savings
