XT09-PKI-R Equivalent & Substitute Parts

Part Overview

The XT09-PKI-R is an RF modem operating in the 902MHz to 928MHz ISM band, designed for wireless serial communication applications. Manufactured by Digi as part of the XTend® series, this component provides RS232/485 interface connectivity with a maximum data rate of 115.2kbps. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XT09-PKI-R is determined by the following critical parameters:

• Frequency Range: 902MHz ~ 928MHz ISM band operation
• Supply Voltage: 7V ~ 28V compatibility
• Sensitivity: -110dBm receiver performance
• Power Output: 30dBm transmission capability
• Series Compatibility: XTend® product family

The XTP9B-PKI-R qualifies as a direct substitute based on matching frequency range, supply voltage, sensitivity, and power output specifications. Both components operate within the same ISM band and maintain equivalent RF performance characteristics. The primary difference lies in interface type and data rate capability, which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The XTP9B-PKI-R is an active product with current manufacturing support, whereas the XT09-PKI-R is obsolete. Both components maintain identical RF performance specifications (frequency, sensitivity, power output) and supply voltage requirements. The XTP9B-PKI-R offers a higher maximum data rate of 125kbps compared to 115.2kbps, providing additional bandwidth capacity.

Selection between these components depends on interface compatibility requirements. The XT09-PKI-R provides DB9 connector interface, while the XTP9B-PKI-R uses a generic Serial interface. System designs must accommodate the interface difference through appropriate connector or adapter solutions.

Both components carry REACH Unaffected compliance status, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the XTP9B-PKI-R directly replace the XT09-PKI-R in existing systems?

A: RF performance and power supply compatibility are equivalent. Interface type differs (DB9 versus Serial), requiring mechanical and electrical interface adaptation.

Q: What are the critical parameters for substitution compatibility?

A: Frequency range (902MHz ~ 928MHz), supply voltage (7V ~ 28V), sensitivity (-110dBm), and power output (30dBm) must match. Both components meet these criteria.

Q: Why is the XT09-PKI-R listed as obsolete?

A: The XT09-PKI-R has been discontinued by the manufacturer. The XTP9B-PKI-R represents the active product line continuation within the XTend® series.

Q: Does the higher data rate of XTP9B-PKI-R (125kbps vs 115.2kbps) affect compatibility?

A: The higher data rate provides additional capability and does not create compatibility issues. Legacy systems operating at 115.2kbps will function with the substitute component.

Q: Are there packaging differences between these components?

A: The XT09-PKI-R packaging is listed as standard, while the XTP9B-PKI-R is supplied in Box packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the difference between ISM and FSK modulation protocols listed for these parts?

A: Both components operate within the ISM band. The modulation protocol difference reflects the technical implementation approach. Both maintain equivalent RF performance in the 902MHz ~ 928MHz frequency range.
