NRF2402G-REEL7

Overview

The NRF2402G-REEL7 is a single-chip RF transmitter manufactured by Nordic Semiconductor ASA, designed for the 2.4 GHz ISM band. It operates within a supply voltage range of 1.9 V to 3.6 V and supports data rates up to 1 Mbps using GFSK modulation. The device features an output power of 0 dBm and consumes approximately 11.5 mA during transmission. Packaged in a 16-VQFN (4x4 mm) surface-mount format with exposed pads, it functions as a shockburst transmitter compatible with Nordic's proprietary protocols. The component supports a 3-wire interface and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Shockburst protocol support for simplified system design
• Single-chip integration of RF transmitter functionality
• Low-power operation suitable for battery-driven applications

Applications

• Home automation systems
• Remote keyless entry (RKE)
• Telemetry and remote sensing

Procurement Notes

This component is officially listed as End-of-Life (EOL) by Nordic Semiconductor, with discontinuation effective March 15, 2021. Verification of current availability requires direct consultation with authorized distributors or manufacturers, as standard production has ceased. Procurement should focus on identifying remaining stock from certified sources or evaluating approved replacement alternatives to ensure supply chain continuity.

Selection Notes

Select this component only if a dedicated transmitter solution is required rather than a transceiver. It is suitable for designs utilizing Nordic’s Shockburst protocol for low-overhead communication. Engineers must account for its EOL status when initiating new designs, prioritizing long-term supply stability. Verify that the 16-VQFN package dimensions and thermal requirements align with the target PCB layout constraints.

Part Context

The NRF2402G belongs to Nordic Semiconductor’s legacy line of 2.4 GHz wireless solutions, specifically engineered for simple, cost-effective point-to-point communication. As a transmitter-only variant, it complements receiver counterparts like the nRF2401 series. This product family established foundational capabilities for IoT devices before the widespread adoption of Bluetooth Low Energy and modern multi-protocol SoCs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the component's End-of-Life status. Designers should consult Nordic Semiconductor for official obsolescence notices and recommended migration paths to current product families.
