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
