Automotive Connectors STAC64 ASSY R/A RCPT 12 SCKT BRN POL C 347290122

Product Description

To address the exponentially growing electronic device requirements within today's advanced vehicles, Molex has engineered the highly versatile modular 0.64, 1.50, and 2.80mm terminal header system. The Stac64 connection system empowers original equipment manufacturers and specialized device integrators with unprecedented design flexibility. This architecture is meticulously crafted to support both highly sensitive low-level signal requirements and demanding power applications up to 30.0A, ensuring comprehensive electrical coverage for modern vehicular networks.

The inherent brilliance of the Stac64 system lies in its structural modularity. It allows automotive manufacturers to utilize header assemblies as discrete, stand-alone components or to gang multiple headers together securely. This modular stacking capability supports a vast array of signal and power needs for diverse devices and control modules without the prohibitive costs or extended lead times typically associated with custom tooling. The standard product line, particularly those based on the 0.64mm pitch terminal, includes 8-, 12-, 16-, and 20-circuit connectors available in both vertical and right-angle configurations. Additionally, 10- and 14-circuit power pocket versions are available to support heavier power applications for 1.50 and 2.80mm pitch terminal systems.

Seamless Compatibility & System Integration

A critical advantage for engineering teams is the system's backward and forward compatibility. These receptacles mate flawlessly with existing wire-harness connectors designed to strict USCAR/EWCAP industry footprints. Furthermore, Stac64 headers are fully stackable with Molex’s HS Stac headers, which feature the high-speed USCAR-30 HSAutolink interface. By combining high-speed connectivity with the standard Stac64 I/O interface, custom multi-bay connection systems can be rapidly developed and deployed, streamlining the integration process across complex vehicle architectures.

Cost Efficiency & Accelerated Development Cycles

• High Cavitation Tooling: The Stac64 standard product offering is tooled at high cavitation, ensuring consistent output and structural uniformity across large-scale production runs.
• Pre-Validated Reliability: Fully validated at the single-pocket level, this system bypasses the need for redundant testing phases.
• Reduced Time-to-Market: By eliminating the need for additional, expensive custom tooling, procurement teams and project managers can significantly reduce development overhead and accelerate the transition from prototyping to full-scale assembly.

During assembly, technicians will appreciate the distinct, reassuring tactile feedback of the secure crimp termination, confirming that the connection is solidly locked into place. The robust feel of the housing, combined with the visual assurance of its specific polarization, minimizes assembly errors and enhances overall production efficiency.

Product Specifications

Engineering Advantages & Environmental Resilience

Uncompromising Industry Certifications

Reliability is non-negotiable in automotive electronic architectures. This Stac64 standard product system is rigorously designed around USCAR-2 Class II mechanical and electrical performance characteristics, specifically optimized for unsealed connector applications. Strict adherence to these industry benchmarks, alongside comprehensive RoHS compliance, guarantees that the assemblies will perform predictably under continuous mechanical stress, ensuring the utmost safety and operational integrity for the end-user.

Material Durability & Thermal Stability

Constructed to endure the unforgiving conditions of automotive environments, this 12-position receptacle housing is molded in a distinctive brown thermoplastic that provides both structural rigidity and immediate visual Polarization C identification. The system utilizes high-grade tin contact plating, which offers excellent electrical conductivity while actively resisting oxidation over extended periods. Engineered for extreme thermal fluctuations, the connector maintains flawless operation across a wide temperature gradient, from a freezing -40°C up to a scorching +100°C. This thermal resilience ensures continuous signal integrity whether the vehicle is operating in arctic cold or intense engine-bay heat.

Core Application Scenarios

Designed primarily for automotive and critical signal applications, this receptacle excels in environments requiring dependable, long-term connections. Its straight mounting angle, 2.54 mm pitch, and secure crimp termination style make it an ideal choice for complex wire-to-board integrations. From advanced infotainment systems and interior lighting controls to essential body electronics, the impressive 500V voltage rating and 10A current capacity provide the necessary electrical headroom to handle a wide spectrum of functional requirements without degrading the signal path during unexpected power surges.
