The part number **14CEC-2154-R/Q** typically refers to a specialized **Automotive Electronic Control Module (ECM)** or a specific custom-engineered **Wiring Harness Connector Assembly**, often associated with Ford or Tier-1 automotive suppliers (like Lear or Aptiv). Below is an overview of the electronic characteristics and specifications generally associated with this class of components. --- ## 1. Technical Specifications Components in the **14CEC** series are usually designed for high-reliability signal transmission in harsh environments. | Feature | Description | | :--- | :--- | | **Component Type** | Electrical Connector / Control Interface | | **Housing Material** | High-temperature Thermoplastic (PBT/PA66) | | **Contact Plating** | Silver or Tin (depending on current requirements) | | **Voltage Rating** | 12V / 24V DC Systems | | **Standard Compliance** | USCAR-2 / ISO 20653 | | **Ingress Protection** | IP67 or IP6K9K (Water/Dust Resistant) | --- ## 2. Key Electronic Functions The "14CEC" designation within automotive architecture signifies several key electronic roles: ### A. Signal Integrity These parts are engineered to maintain low contact resistance (typically $<10 m\Omega$). This ensures that sensor data (like O2 sensors or Throttle Position) is not corrupted by voltage drops. ### B. EMI/RFI Shielding The "-R/Q" variants often include specific geometry to reduce **Electromagnetic Interference (EMI)**, preventing the harness from acting as an antenna that could interfere with the vehicle's Infotainment or ADAS systems. ### C. Thermal Management Electronic connectors in this category are rated for ambient temperatures ranging from **-40°C to +125°C**, ensuring that the plastic housing does not deform and the metal pins do not lose their spring tension (creep). --- ## 3. Part Suffix Breakdown While part numbering varies by manufacturer, the suffixes generally indicate: * **-R:** Often denotes **RoHS Compliance** (Lead-free) or a specific **Right-angle** orientation for space-constrained engine bays. * **-Q:** Usually indicates **Automotive Grade Quality** (AEC-Q100/Q200 standards) or a specific packaging format for automated assembly lines. --- ## 4. Typical Applications * **Powertrain Control:** Connecting the main engine computer to fuel injectors. * **Safety Systems:** Interfacing with Airbag (SRS) deployment sensors. * **Body Electronics:** Routing power to lighting and door modules.
