In the electronics industry, the term **.080P** typically refers to the **pitch** of a connector or a component's lead spacing. The "P" stands for **Pitch**, and the numerical value represents the distance between the centers of two adjacent pins or conductors. --- ### 1. Understanding the Measurement In engineering specifications, ".080" is an Imperial measurement (inches). To understand its physical size in the global standard (Metric), we convert it: | Unit | Measurement | | :--- | :--- | | **Inches** | 0.080" | | **Millimeters** | 2.032 mm | | **Commonly Referred to as** | 2.0 mm Pitch (Approximate) | --- ### 2. Common Components with .080P While **2.54mm (0.100")** is the most common standard for breadboards, the **2.0mm / .080"** pitch is widely used in compact electronics where space is limited but high reliability is required. #### A. Pin Headers and Receptacles * Used to connect two PCBs (Printed Circuit Boards) together. * Found in smaller microcontrollers (like some XBee modules or specialized sensors). #### B. JST and Molex Connectors * Many **Wire-to-Board** connectors use a 2.0mm (.080") pitch to balance current-carrying capacity with a small footprint. * Common examples include the **JST-PH series**. #### C. FFC/FPC (Flexible Flat Cables) * High-density ribbon cables often use smaller pitches, but 2.0mm (.080") is standard for industrial-grade flexible connections. --- ### 3. Comparison with Other Standards It is crucial to distinguish .080P from its "neighbors" to avoid fitment issues: | Pitch Type | Measurement (Inches) | Measurement (mm) | Usage | | :--- | :--- | :--- | :--- | | **.050P** | 0.050" | 1.27 mm | Half-pitch headers | | **.080P** | **0.080"** | **2.032 mm** | **Compact connectors (JST PH)** | | **.100P** | 0.100" | 2.54 mm | Standard Breadboard/Arduino | --- ### 4. Why use .080P? 1. **Space Efficiency:** It is roughly 20% smaller than the standard 0.1" pitch, allowing for more pins in a smaller area. 2. **Vibration Resistance:** Connectors in this size often feature locking ramps (like the JST-PH), making them better for drones or automotive electronics than standard loose headers. 3. **Standardization:** It is the go-to size for internal battery connections in many consumer electronics (laptops, portable speakers). --- ### Technical Note on Suffixes If you see ".080P" on a datasheet, ensure you check if it refers to: * **Row-to-Row Spacing:** The distance between two rows of pins. * **Pin-to-Pin Spacing:** The distance between pins in the same row (the most common meaning).
