Identified by the hardware version number A1453, this model is distinguished by its specific regulatory certifications, including an FCC product code of -E2642A. It falls under the broader classification of the iPhone 5S product line, which was originally released on September 10, 2013. ## Key Facts * **Parent Product:** The model is a subclass of the iPhone 5S, a smartphone introduced by Apple on September 10, 2013. * **Model Identifier:** The hardware version identification number is **A1453**. * **FCC Certification:** The device carries the FCC product code **-E2642A**. * **Radio Certification:** It holds the radio equipment list certification number **579C-E2642A**. * **Head SAR (1g):** The specific absorption rate (SAR) over 1g of tissue is **1.18 W/kg** (applicable to head and body). * **Head SAR (10g):** The specific absorption rate (SAR) over 10g of tissue is **0.93 W/kg** (applicable to the head). * **Body SAR (10g):** The specific absorption rate (SAR) over 10g of tissue is **0.99 W/kg** (applicable to the body). * **Classification:** Defined as an instance of a "product model." ## FAQs ### Q: What is the specific absorption rate (SAR) for the iPhone 5s model A1453? A: The model A1453 has a specific absorption rate (SAR) of 1.18 watts per kilogram when measured over 1g of tissue. When measured over 10g of tissue, the values are 0.93 W/kg for the head and 0.99 W/kg for the body. ### Q: What are the regulatory identification numbers for this model? A: The model is identified by the hardware version number A1453, the FCC product code -E2642A, and the radio equipment list certification number 579C-E2642A. ### Q: Which iPhone series does the A1453 belong to? A: The A1453 is a model variant of the iPhone 5S series, which was originally unveiled on September 10, 2013. ## Why It Matters The iPhone 5s, model A1453, serves as a critical entry in technical and regulatory databases because it represents the precise hardware configuration of the iPhone 5S for specific markets. While the general consumer interacts with the device simply as an "iPhone 5S," the distinction of the A1453 model is essential for regulatory compliance, particularly concerning radio frequency exposure and hardware certification. This model entry provides the definitive legal and technical specifications required by government bodies such as the FCC. By documenting the exact Specific Absorption Rate (SAR)—1.18 W/kg over 1g of tissue—and certification numbers like 579C-E2642A, this data ensures the device is verified as safe for consumer use regarding radio frequency emissions. Consequently, this knowledge entry is vital for technicians, regulatory compliance officers, and telecom professionals who require granular details to distinguish this specific hardware iteration from other global variants of the iPhone 5S. ## Notable For * **Regulatory Identification:** Distinguished by the specific FCC product code -E2642A. * **RF Safety Metrics:** Documented with specific SAR values (1.18 W/kg max) for safety compliance. * **Hardware Classification:** Serves as a distinct subclass of the iPhone 5S, differentiating it from other model numbers in the same series. * **Certification Tracking:** Identified by the unique Radio Equipment List certification number 579C-E2642A. ## Body ### Classification and Lineage The iPhone 5s, model A1453, is technically classified as a "product model" and acts as a subclass of the parent device, the **iPhone 5S**. The parent smartphone was initially announced with an inception date of **September 10, 2013**. While the iPhone 5S is the general product line, the A1453 denotes a specific version of that hardware, maintaining the core identity of the smartphone while possessing unique regulatory identifiers. ### Hardware and Regulatory Identifiers To distinguish this specific unit within the supply chain and regulatory databases, the model is assigned several key identifiers: * **Hardware Version Identification Number:** A1453 * **FCC Product Code:** -E2642A * **Radio Equipment List Certification Number:** 579C-E2642A These codes are used to verify the device's compliance with communication standards and to authorize its operation on radio frequencies. ### Radio Frequency Exposure (SAR) The model A1453 has been tested for Specific Absorption Rate (SAR), a measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field. The documented values for this model are: * **1.18 W/kg:** Measured over 1g of tissue (Head and Body). * **0.93 W/kg:** Measured over 10g of tissue (Head). * **0.99 W/kg:** Measured over 10g of tissue (Body). These measurements indicate the maximum RF energy exposure levels allowed for this specific hardware configuration. All data is verified via Apple's legal RF exposure documentation. ## References 1.
