Key Parameters

Substitute Part Grouping Explanation

Substitution of the HORNET200-TX3 is determined by strict alignment of the following critical parameters:

Frequency Alignment: Both the main part and substitute must operate at 433.92MHz to ensure compatibility with existing receiver infrastructure and regulatory compliance within the ISM band.

Modulation Protocol: The primary modulation must be FM to maintain signal integrity with existing receiver systems. Extended protocol support (FSK, Digital) in substitute parts does not disqualify compatibility when FM remains the base modulation.

Power Output: The 10dBm output specification must be maintained to ensure consistent transmission range and system performance.

Supply Voltage: The 2V to 3.3V operating range must be preserved to ensure compatibility with existing power supply designs.

Environmental Rating: IP68 rating must be maintained to preserve ingress protection characteristics in the application environment.

RoHS Compliance: ROHS3 compliance is required for regulatory and procurement consistency.

The FOBBER-4T3 satisfies all substitution criteria while offering extended interface capabilities (Digital, Relay, Serial) and active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: FOBBER-4T3 is the qualified substitute for HORNET200-TX3 applications.

Justification: The FOBBER-4T3 maintains all critical electrical parameters (frequency, modulation, power output, supply voltage) and environmental specifications (IP68 rating) required for direct substitution. The component holds active product status, ensuring long-term availability and supply chain continuity. ROHS3 compliance is maintained across both components, satisfying regulatory requirements.

Status Transition: Migration from the obsolete HORNET200-TX3 to the active FOBBER-4T3 provides enhanced interface flexibility through digital, relay, and serial capabilities while preserving core FM transmission functionality at 433.92MHz.

Compliance Continuity: Both components share identical ECCN classification (EAR99) and equivalent regulatory standing, supporting seamless procurement and deployment transitions.

Frequently Asked Questions (FAQ)

Q: Can FOBBER-4T3 directly replace HORNET200-TX3 in existing designs?

A: Yes. The FOBBER-4T3 maintains identical frequency (433.92MHz), power output (10dBm), supply voltage range (2V to 3.3V), and environmental rating (IP68). FM modulation compatibility is preserved, enabling direct substitution in applications utilizing FM transmission protocols.

Q: What is the significance of FSK protocol support in FOBBER-4T3?

A: The FOBBER-4T3 supports both FM and FSK modulation protocols. Existing systems utilizing FM modulation operate without modification. The FSK capability provides extended functionality for applications requiring digital modulation without affecting FM-based implementations.

Q: How do the interface differences affect substitution?

A: HORNET200-TX3 provides handheld, three-button interface. FOBBER-4T3 adds digital, relay, and serial interface options. These extended interfaces do not prevent FM handheld operation; they provide additional integration pathways for advanced control systems. Existing handheld implementations remain fully functional.

Q: What packaging considerations apply to this substitution?

A: HORNET200-TX3 is specified with dash packaging notation. FOBBER-4T3 is supplied in bulk packaging. Procurement and inventory management processes must account for bulk packaging requirements when transitioning to the substitute component.

Q: Why is product status relevant to this substitution?

A: HORNET200-TX3 is classified as obsolete, indicating discontinued manufacturing and limited future availability. FOBBER-4T3 holds active status, ensuring continued production, supply chain support, and long-term component availability for new designs and maintenance applications.

Q: Are there regulatory differences between these components?

A: Both components maintain ROHS3 compliance and identical ECCN classification (EAR99). Regulatory standing is equivalent, supporting consistent procurement and deployment across both components without additional compliance documentation.
