The **PA3428L-N24-R** is a specific electronic component primarily recognized as an **Incandescent Lamp** or **Miniature Bulb**, typically used in automotive dashboards, industrial indicators, or specialized electronic panels. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. Technical Specifications This part is designed for low-voltage, high-reliability environments. | Parameter | Specification | | :--- | :--- | | **Lamp Type** | Incandescent / Miniature | | **Operating Voltage** | 14.0 V (Standard for 12V automotive systems) | | **Current Rating** | ~0.08 A (80mA) | | **Brightness (MSCP)** | 0.30 ± 25% (Mean Spherical Candlepower) | | **Life Span** | ~15,000 Hours | | **Filament Type** | C-2V | | **Base Type** | Neo-Wedge (Plastic Twist-Lock) | --- ### 2. Physical Characteristics The "N24" designation often refers to the specific plastic base (Neo-Wedge) used to seat the bulb into a Printed Circuit Board (PCB). * **Form Factor:** T-1 or T-1.25 (Sub-miniature). * **Base Material:** Heat-resistant plastic (usually black or grey). * **Mounting:** Twist-lock mechanism that allows the bulb to be installed directly into the PCB traces without soldering. * **Contacts:** Two metal tabs on the side of the plastic base that complete the circuit when twisted into place. --- ### 3. Application Areas Because of its 14V rating and vibration-resistant filament, it is commonly found in: * **Automotive Instrument Clusters:** Backlighting for speedometers and fuel gauges. * **Climate Control Panels:** Lighting for AC/Heater buttons. * **Avionics:** Cockpit indicators in older light aircraft. * **Industrial Controls:** Status indicators on machinery panels. --- ### 4. Comparison: Incandescent vs. LED Replacements While the PA3428L-N24-R is a traditional filament bulb, many users now look for LED alternatives. | Feature | PA3428L (Original) | LED Equivalent | | :--- | :--- | :--- | | **Light Output** | Warm/Yellowish (3000K) | Cool White/Colors (6000K+) | | **Heat Emission** | High | Low | | **Power Consumption** | Moderate | Very Low | | **Polarity** | Non-polar (Works either way) | Polar (Must be oriented correctly) | --- ### 5. Part Number Breakdown * **PA:** Manufacturer prefix (often associated with specialized lighting brands like JKL Components or Oshino). * **3428:** The specific glass bulb and filament configuration. * **N24:** The Neo-Wedge base size/specification. * **R:** Often denotes RoHS compliance (lead-free).
