Key Parameters

Substitute Part Grouping Explanation

Substitution of the HORNET200-TX2 is based on the following critical parameters that must align between the main part and substitute components:

Frequency Compatibility: Both the main part and substitute operate within the 433MHz ISM band, with the HORNET200-TX2 at 433.92MHz and the substitute at 433MHz. This frequency range overlap permits functional substitution in general-purpose RF applications.

Modulation Type: Both components utilize FM modulation, ensuring signal compatibility with existing receiver infrastructure.

Power Output: The main part delivers 10dBm output; the substitute provides 10mW output. These specifications are equivalent in RF transmission capability.

Supply Voltage: The main part operates at 2V to 3.3V; the substitute operates at 2.9V to 3.3V. The overlapping voltage range (2.9V to 3.3V) permits direct substitution within this common operating window.

Environmental Rating: Both components feature IP68 protection, maintaining equivalent environmental sealing and durability characteristics.

Regulatory Compliance: Both parts are ROHS3 compliant and classified under ECCN EAR99, ensuring equivalent regulatory standing.

Parameter Comparison

Engineering Selection Recommendations

The FOBBER-4T2 serves as the direct substitute for the obsolete HORNET200-TX2 based on the following engineering criteria:

Product Status Alignment: The FOBBER-4T2 maintains active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The HORNET200-TX2 is obsolete and no longer actively manufactured or supported.

Regulatory Compliance: Both components maintain ROHS3 compliance and EAR99 classification, ensuring equivalent regulatory standing for applications requiring compliance documentation.

Frequency Band Operation: Both transmitters operate within the 433MHz ISM band with FM modulation, permitting functional integration into existing receiver systems designed for this frequency range.

Supply Voltage Overlap: The common voltage operating range of 2.9V to 3.3V permits direct substitution in applications operating within this window. Applications requiring operation below 2.9V require additional circuit design consideration.

Environmental Protection: Both components feature IP68 rating, maintaining equivalent environmental sealing for outdoor and harsh environment applications.

Frequently Asked Questions (FAQ)

Q: Can the FOBBER-4T2 directly replace the HORNET200-TX2 in existing applications?

A: Direct substitution is supported for applications operating within the common supply voltage range of 2.9V to 3.3V. Applications requiring operation at 2V to 2.9V require circuit redesign or alternative component selection.

Q: What is the frequency difference between these two transmitters?

A: The HORNET200-TX2 operates at 433.92MHz while the FOBBER-4T2 operates at 433MHz. Both frequencies fall within the 433MHz ISM band and are compatible with standard 433MHz receiver modules.

Q: Are there packaging differences between these components?

A: The HORNET200-TX2 packaging is specified as dash (standard); the FOBBER-4T2 is supplied in bag packaging. Verify packaging requirements for your assembly process.

Q: Do both transmitters provide equivalent RF output power?

A: Yes. The HORNET200-TX2 provides 10dBm output; the FOBBER-4T2 provides 10mW output. These specifications are equivalent in RF transmission capability.

Q: What is the operational range difference?

A: The FOBBER-4T2 specifies a 100m range. The HORNET200-TX2 does not provide a specified range parameter in the available documentation.

Q: Are both components RoHS compliant?

A: Yes. Both the HORNET200-TX2 and FOBBER-4T2 are ROHS3 compliant and classified under ECCN EAR99.

Q: What inventory status should I consider for procurement?

A: The HORNET200-TX2 has 1171 pieces in stock but is obsolete. The FOBBER-4T2 has 695 pieces in stock and maintains active product status, ensuring continued availability for future orders.
