HORNET200-TX1 Equivalent & Substitute Parts

Part Overview

The HORNET200-TX1 is an RF transmitter key fob operating at 433.92MHz with FM modulation, designed for general-purpose handheld applications. This single-button transmitter delivers 10dBm output power and operates across a 2V to 3.3V supply range. The product is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure ongoing component availability for production and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HORNET200-TX1 is determined by alignment across the following critical parameters:

Frequency Compatibility: The substitute must operate within the 433MHz ISM band. The HORNET200-TX1 operates at 433.92MHz, and the FOBBER-4T1 operates at 433MHz, both within the same regulatory frequency band for general-purpose RF transmission.

Modulation Protocol: Both the main part and substitute employ FM modulation, ensuring signal compatibility with existing receiver infrastructure.

Power Output: The HORNET200-TX1 delivers 10dBm, while the FOBBER-4T1 delivers 10mW (approximately 10dBm), maintaining equivalent transmission power.

Supply Voltage Range: The HORNET200-TX1 operates at 2V to 3.3V, and the FOBBER-4T1 operates at 2.9V to 3.3V. The FOBBER-4T1 voltage range is a subset of the original specification, requiring verification of minimum voltage requirements in the application circuit.

Environmental Rating: Both components feature IP68 protection, confirming equivalent environmental sealing for handheld applications.

Regulatory Compliance: Both parts are ROHS3 compliant and carry EAR99 ECCN classification, meeting identical regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The FOBBER-4T1 serves as the manufacturer-recommended substitute for the obsolete HORNET200-TX1. Both components are manufactured by RF Solutions and maintain identical functional classifications as FM transmitters within the 433MHz ISM band.

Product Status Consideration: The HORNET200-TX1 is classified as obsolete, while the FOBBER-4T1 maintains active product status with confirmed inventory availability (974 pieces in stock). This status differential directly supports the substitution pathway for ongoing production and field replacement requirements.

Compliance Alignment: Both components achieve ROHS3 compliance and carry identical ECCN classification (EAR99), eliminating regulatory barriers to substitution. Packaging differences (HORNET200-TX1 unspecified versus FOBBER-4T1 in bag format) do not affect functional equivalence.

Voltage Supply Range: The FOBBER-4T1 voltage range (2.9V to 3.3V) represents a narrower specification than the HORNET200-TX1 (2V to 3.3V). Applications operating below 2.9V require circuit-level evaluation to confirm compatibility with the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the FOBBER-4T1 directly replace the HORNET200-TX1 in existing designs?

A: The FOBBER-4T1 is functionally equivalent across frequency, modulation, power output, and environmental protection specifications. However, the reduced minimum supply voltage (2.9V versus 2V) requires verification that the application circuit operates above this threshold. Mechanical packaging differences must also be evaluated for form-factor compatibility.

Q: What is the frequency difference between 433.92MHz and 433MHz, and does it affect receiver compatibility?

A: Both frequencies operate within the 433MHz ISM band. The 0.92MHz offset is within typical receiver bandwidth tolerances for FM-modulated signals in this frequency range. Receiver selectivity and filter characteristics determine whether this offset introduces compatibility issues in specific applications.

Q: Are there differences in the button interface between these components?

A: The HORNET200-TX1 specifies a handheld, 1-button interface. The FOBBER-4T1 describes a 1-channel transmitter without explicit interface detail. Physical evaluation of the FOBBER-4T1 is required to confirm button configuration and mechanical compatibility with existing enclosures or mounting schemes.

Q: What does the 100m range specification on the FOBBER-4T1 indicate?

A: The 100m range represents the operational distance under specified conditions. This specification does not appear on the HORNET200-TX1 datasheet. Both components deliver equivalent power output (10dBm/10mW), and range performance depends on receiver sensitivity, antenna design, and environmental factors not detailed in the provided parameters.

Q: How does the packaging difference affect component selection?

A: The HORNET200-TX1 packaging is unspecified, while the FOBBER-4T1 is supplied in bag format. Packaging affects handling, storage, and integration into production workflows but does not alter electrical or functional characteristics. Confirm that bag packaging meets your procurement and assembly requirements.

Q: Is the FOBBER-4T1 the only available substitute?

A: Based on the provided manufacturer recommendation, the FOBBER-4T1 is identified as the primary substitute. Additional equivalent components may exist from other manufacturers, but they are not included in this reference documentation.
