The **W2SP-2BC-R/Q** is a specific part number typically associated with high-performance **Miniature Incandescent Lamps** or specialized **LED Indicators** often used in automotive, industrial, and avionics control panels. Below is a technical breakdown of the component characteristics based on the standard nomenclature for this series. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | T-1 Sub-Miniature Lamp / LED | | **Base Style** | Bi-Pin (Standard 2-pin spacing) | | **Operating Voltage** | Typically 5V, 12V, or 28V (model dependent) | | **Luminous Color** | Clear (R/Q variants often imply specific color filters or high-output) | | **Life Expectancy** | 5,000 to 40,000 hours (depending on voltage) | | **Housing Material** | High-temperature resistant plastic/glass | --- ### 2. Breakdown of the Part Number While nomenclature varies slightly by manufacturer (such as JKL Components or Oshino), the code usually breaks down as follows: * **W2SP**: The series designation, identifying it as a sub-miniature lamp with specific physical dimensions (often T-1 or T-1 3/4 size). * **2BC**: Refers to the **Bi-Pin** contact configuration. The "2" indicates two pins, and "BC" often refers to the center-to-center pin spacing. * **R/Q**: These are quality or environmental rating suffixes. * **R**: Often stands for "RoHS Compliant." * **Q**: Can indicate "Qualified" for specific aerospace or military standards (MIL-SPEC). --- ### 3. Key Applications These parts are designed for precision environments where space is limited and reliability is critical: 1. **Avionics & Cockpits**: Backlighting for instrument clusters and radio displays. 2. **Industrial Controls**: Indicator lights on PLCs (Programmable Logic Controllers) and CNC machinery. 3. **Medical Equipment**: Status indicators on diagnostic handheld devices. 4. **Automotive**: Luxury interior lighting and dashboard switches. --- ### 4. Installation & Handling ```markdown ### Precautions - **Static Sensitivity**: If the "Q" variant uses LED technology, use ESD-safe handling. - **Voltage Matching**: Ensure the power supply matches the rated voltage; over-voltage significantly reduces the lifespan of filament-based lamps. - **Pin Alignment**: The pins are fragile; ensure vertical alignment before inserting into the socket to avoid bending. ``` ---
