Key Parameters

Substitute Part Grouping Explanation

Substitute components for the XT09-PKD-RD are identified based on the following critical parameters that determine functional equivalence:

• Frequency Range: 902MHz ~ 928MHz ISM band operation
• Modulation/Protocol: FHSS and FSK support
• Serial Interface: RS-232 and RS-422/485 compatibility
• Function: RF transceiver modem capability
• Moisture Sensitivity: MSL 1 rating

The CL4490-1000-PRO from Laird Connectivity Inc. meets these core substitution criteria. Both components operate within the same frequency band, support identical modulation schemes, provide equivalent serial interfaces, and share the same moisture sensitivity classification. The substitute part is classified as active, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The CL4490-1000-PRO is the designated substitute for the obsolete XT09-PKD-RD based on functional equivalence across core RF and interface parameters. The substitute component is classified as active, ensuring long-term availability and manufacturing support. The CL4490-1000-PRO carries RoHS compliance certification, providing regulatory advantage over the legacy XT09-PKD-RD for new designs and system upgrades. Both components maintain identical moisture sensitivity ratings and REACH compliance status, supporting equivalent environmental handling and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: What makes the CL4490-1000-PRO a valid substitute for the XT09-PKD-RD?

A: Both components operate within the 902MHz to 928MHz frequency band, support FHSS and FSK modulation, and provide RS-232 and RS-422/485 serial interfaces. These core parameters define functional equivalence for RF transceiver modem applications.

Q: Are there differences in sensitivity between the two parts?

A: The XT09-PKD-RD specifies -110dBm sensitivity, while the CL4490-1000-PRO specifies -99dBm sensitivity. This 11dB difference represents a measurable change in receiver performance and should be evaluated against specific application requirements.

Q: What is the packaging difference between these components?

A: The XT09-PKD-RD packaging is listed as unspecified in available documentation. The CL4490-1000-PRO is supplied in bulk packaging. Packaging compatibility must be confirmed against system integration requirements.

Q: Does the CL4490-1000-PRO provide additional features?

A: The CL4490-1000-PRO specifies 1000mW power output, 76.8kbps maximum data rate, and 450m range capability. The XT09-PKD-RD does not provide these specifications in available documentation.

Q: Are both components suitable for the same applications?

A: Both components are classified for general purpose applications within the 902MHz to 928MHz ISM band. Application suitability depends on specific system requirements including sensitivity, data rate, power output, and supply voltage compatibility.

Q: What is the supply voltage requirement for the substitute part?

A: The CL4490-1000-PRO requires 7V to 18V supply voltage. The XT09-PKD-RD supply voltage is not specified in available documentation and must be confirmed from original design documentation.
