Molex Stac64 Unsealed 'STACable' Connection Systems
Stackable connection system provides single and multi-pocket PCB solutions, offering a diverse range of circuit sizes and greatly reduces time-to-market by completely eliminating custom tooling
To address the growing electronic device requirements within today's vehicles, Molex has developed a modular 0.64, 1.50 and 2.80mm (.025, .059 and .110") terminal header system.

The Stac64 connection 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 system 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 standard product line based on the 0.64mm (.025") pitch terminal includes: 8-, 12-, 16- and 20-circuit connectors in both vertical and right-angle headers supporting low-level signal requirements. An additional 10-circuit 'power pocket' version, supporting power applications for 1.50 and 2.80mm (.059 and .110") pitch terminal systems, is available in vertical and right- angle configurations. This 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.
The Stac64 standard product offering is currently tooled at high cavitation and is fully validated at the single-pocket level. This greatly reduces time-to-market by completely eliminating the need for additional tooling.
Features and Benefits
| |
---|---|
Stackable connection system of readily available PCB headers | Reduced time-to-market: engineering and validation times reduced significantly. No tooling necessary to produce custom multi-bay headers |
The 20-circuit-header housings are molded in standard USCAR color schemes for additional polarizations | Matches harness connector color coding scheme for visual aid in assembly |
Pre-assembled, linear Mylar PC tail alignment strip for right angle headers | Reduces PCB packaging complexity. 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 board through-holes during assembly. Retain header to PCB during assembly and solder processing |
PCB standoffs molded into housings | Provide additional trace-routing real estate underneath the headers |
High temperature thermoplastic housing | Withstand infra red (IR) and wave lead-free solder processing per SMES-152 Molex specification |
Pre-assembled TPA to receptacle housing shipped as single assembly | Applied labor and cost savings |
