The part number **1969608-7** refers to a specific connector in the **Economy Power (EP) 2.5** series manufactured by **TE Connectivity**. Below is a detailed breakdown of its specifications, design features, and applications. ### 1. Part Identification | Feature | Description | | :--- | :--- | | **Manufacturer** | TE Connectivity | | **Part Number** | 1969608-7 | | **Product Line** | Economy Power (EP) 2.5 | | **Component Type** | Housing (Plug) | | **Connector System** | Wire-to-Board / Wire-to-Wire | --- ### 2. Technical Specifications This component is a plastic housing designed to hold crimp terminals. * **Number of Positions:** 7 Positions. * **Pitch (Centerline):** 2.5 mm (0.098 inches). * **Number of Rows:** 1 (Single Row). * **Color:** Natural (White). * **Material:** Nylon (UL 94V-0 rated). * **Locking Style:** Positive Lock (ensure secure connection with a latch). * **Glow Wire Rating:** This specific part is often "Glow Wire Capable" (check specific datasheet revisions for compliance with IEC 60335-1). --- ### 3. Key Design Features 1. **Compact Pitch:** The 2.5mm spacing allows for high-density connections on PCBs where space is limited. 2. **Polarization:** The housing is designed with physical keys to prevent accidental "mismating" (plugging it in backward or into the wrong slot). 3. **TPA Compatibility:** This series supports **Terminal Position Assurance (TPA)** retainers. TPAs are secondary locks that ensure the metal pins are fully seated and cannot be backed out under vibration. 4. **Audible Click:** The positive locking latch provides tactile and acoustic feedback to confirm the connector is fully engaged. --- ### 4. Typical Applications The EP 2.5 series is widely used in commercial and industrial electronics, including: * **Household Appliances:** Refridgerators, washing machines, and water heaters. * **Industrial Controls:** HVAC systems and power supplies. * **Lighting:** LED modules and controllers. --- ### 5. Required Mating Components To use this part in a circuit, you will typically need the following: * **Terminals:** Crimp contacts (e.g., TE series 2110989) sized for 22–26 AWG wire. * **Mating Header:** A PCB-mounted header (straight or right-angle) from the EP 2.5 series. * **TPA Retainer:** (Optional) Part number 1969443-7 for additional terminal security.
