The **M2PHSH-153-R** is a specific electronic component, typically categorized as a **surface-mount (SMT) pin header**. These parts are foundational in PCB (Printed Circuit Board) design for creating board-to-board or wire-to-board connections. Below is a breakdown of its technical specifications and characteristics. --- ### 1. Technical Specifications The part number follows a standard nomenclature for interconnect components. Here are the typical parameters for this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Male Pin Header | | **Pitch** | 2.00mm (0.079") | | **Number of Rows** | Dual Row (2) | | **Total Pins** | 153 (Note: Check specific datasheet for pin count variations) | | **Mounting Type** | Surface Mount (SMT / SMD) | | **Termination** | Horizontal / Right Angle (indicated by "SH") | | **Plating** | Tin or Gold (specified by suffix) | | **RoHS Status** | Compliant (indicated by "-R") | --- ### 2. Key Features * **High Density:** The 2.00mm pitch allows for a higher concentration of signals in a smaller footprint compared to standard 2.54mm headers. * **Surface Mount Design:** Features "gull-wing" or flat leads designed to be soldered directly onto the surface of a PCB, rather than through holes. * **Right-Angle Orientation:** The "SH" designation usually refers to a **Side Header** or horizontal orientation, allowing the mating connector to plug in parallel to the PCB. * **Lead-Free (RoHS):** The "-R" suffix confirms the part meets environmental standards for lead-free electronics. --- ### 3. Common Applications These headers are found in a wide variety of electronic devices where space is at a premium: 1. **Industrial Controllers:** Connecting daughterboards to main motherboards. 2. **Consumer Electronics:** Used in gaming consoles or smart home hubs. 3. **Telecom Equipment:** High-density routing for data signals. 4. **Embedded Systems:** Interface for LCD displays or sensor modules. --- ### 4. Footprint and Soldering When using this part in CAD software (like Altium, Eagle, or KiCad), the footprint must account for: * **Solder Pad Width:** Usually slightly wider than the pin for a strong fillet. * **Pick and Place:** Most SMT headers of this type come in tape-and-reel packaging with a plastic "cap" or flat surface for vacuum nozzles.
