The **M2AS1-6433-R2/Q** is a specialized electronic component, typically categorized as a high-density, high-frequency board-to-board connector or a specific mezzanine-style interconnect. These parts are commonly used in telecommunications, server architecture, and industrial computing. --- ### 1. Component Specification Overview Below is a breakdown of the typical technical attributes associated with this series of connectors. | Feature | Specification | | :--- | :--- | | **Component Type** | Mezzanine Connector / Board-to-Board | | **Pin Configuration** | High-density multi-pin (often 64 to 400+ positions) | | **Data Rate Support** | High-speed differential signaling (up to 10-28 Gbps) | | **Mounting Type** | Surface Mount Technology (SMT) / BGA | | **Contact Material** | Copper Alloy with Gold Plating | | **Housing Material** | High-temperature LCP (Liquid Crystal Polymer) | --- ### 2. Key Technical Characteristics * **High Signal Integrity:** Designed to minimize crosstalk and impedance mismatch, making it suitable for PCIe Gen 3/4 or Ethernet backplanes. * **Mechanical Reliability:** The "R2" and "Q" suffixes often denote specific revisions or qualification standards (such as automotive or industrial grade) that ensure the connector can withstand vibration and thermal cycling. * **Pitch and Alignment:** These connectors feature ultra-fine pitches (often 0.5mm to 1.0mm) and usually include alignment pegs or "bosses" to ensure precise placement on the PCB during the reflow soldering process. --- ### 3. Functional Applications These parts are integral to modular electronic design where one PCB (a "daughter card") must be stacked onto another (a "carrier board"). 1. **Server Blades:** Connecting CPU modules to I/O expansion boards. 2. **Network Switches:** Linking high-speed switching fabrics to line cards. 3. **Medical Imaging:** Transferring large volumes of raw data from sensors to processing units. 4. **Embedded Computing:** Used in COMs (Computer-on-Modules) like COM Express or SMARC. --- ### 4. Part Number Breakdown (General Logic) While specific to the manufacturer (often associated with brands like Samtec, Amphenol, or Hirose styles), the nomenclature usually follows this logic: * **M2AS:** Series designation (Mezzanine, 2mm, or specific family). * **6433:** Often refers to the pin count or the specific height/stacking distance. * **R2:** Revision level or RoHS compliance status. * **Q:** Qualification code (e.g., Automotive Grade or Tape & Reel packaging).
