HORNET-RX 433MHz RF Receiver Equivalent & Substitute Parts

Part Overview

The HORNET-RX is a 433.92MHz FM receiver module manufactured by RF Solutions, designed for general remote control applications. This component operates across a 12V to 30V supply range and features a 100-meter operating range with IP68 environmental protection. The HORNET-RX is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

The obsolete status of the HORNET-RX necessitates sourcing of substitute components that maintain compatibility with existing system architectures while meeting current supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HORNET-RX is determined by the following critical parameters:

Frequency Compatibility: The substitute component must operate at 433.92MHz to maintain compatibility with existing transmitter systems and regulatory allocations.

Voltage Supply Range: The substitute must accommodate the 12V to 30V supply specification of the original design. The QUANTA-4R4 operates at 2.9V to 3.3V, which falls outside the specified supply range of the HORNET-RX.

Functional Classification: Both components serve receiver functions within remote control applications, though the QUANTA-4R4 is classified as a complete remote control system rather than a discrete receiver module.

Modulation Protocol: The HORNET-RX uses FM modulation, while the QUANTA-4R4 uses LoRa modulation. These represent different signal encoding methods and are not directly interchangeable without system-level modifications.

Environmental and Compliance Standards: Both components meet ROHS3 compliance requirements, supporting modern manufacturing and environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The QUANTA-4R4 is listed as a manufacturer-recommended substitute; however, direct substitution requires careful evaluation of system-level requirements.

Voltage Supply Incompatibility: The QUANTA-4R4 operates at 2.9V to 3.3V, which is fundamentally incompatible with the HORNET-RX supply specification of 12V to 30V. Systems designed for the HORNET-RX voltage range cannot directly power the QUANTA-4R4 without additional voltage regulation circuitry.

Modulation Protocol Difference: The transition from FM to LoRa modulation represents a change in signal encoding and receiver architecture. Existing transmitter systems designed for FM modulation will not communicate with LoRa receivers without complete system redesign.

Active Product Status: The QUANTA-4R4 maintains active product status with current manufacturing availability (850 pieces in stock), whereas the HORNET-RX is obsolete. For new designs or system replacements, the QUANTA-4R4 offers supply chain continuity.

Compliance Alignment: Both components meet ROHS3 compliance, supporting regulatory requirements for modern electronics manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the QUANTA-4R4 directly replace the HORNET-RX in existing systems?

A: Direct replacement is not possible without system modifications. The QUANTA-4R4 operates at 2.9V to 3.3V, incompatible with the HORNET-RX 12V to 30V supply specification. Additionally, the modulation protocol differs (LoRa versus FM), requiring transmitter compatibility verification.

Q: What is the primary reason for seeking a substitute for the HORNET-RX?

A: The HORNET-RX is classified as obsolete, indicating discontinued manufacturing and limited availability. The QUANTA-4R4 maintains active status with current production inventory.

Q: Are both components compliant with current environmental standards?

A: Both the HORNET-RX and QUANTA-4R4 meet ROHS3 compliance requirements, supporting modern manufacturing and environmental regulations.

Q: What packaging format is available for the QUANTA-4R4?

A: The QUANTA-4R4 is supplied in box packaging, as specified in the product documentation.

Q: How do the operating frequencies compare?

A: Both components operate at 433.92MHz, maintaining frequency compatibility within the ISM band allocation.

Q: What is the moisture sensitivity level of the QUANTA-4R4?

A: The QUANTA-4R4 is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
