Key Parameters

Substitute Part Grouping Explanation

Substitution of the XA-M94-CS2P-A is determined by the following critical parameters:

• Frequency Band Compatibility: The main part operates in 900MHz and 2.4GHz ISM bands. Substitute parts must support equivalent frequency ranges to maintain system interoperability.
• Interface Protocol Support: The adapter supports RS-232, RS-485, USB, Analog, and Digital interfaces. Substitute components must provide compatible interface options for the target application.
• Data Rate Capability: Maximum data rate of 250kbps establishes the communication speed requirement. Substitutes must meet or exceed this specification.
• RF Performance Metrics: Sensitivity (-100dBm) and Power Output (18dBm) define the link budget and range characteristics. Substitute parts should maintain comparable RF performance.
• Supply Voltage Range: Operating voltage of 3.7V ~ 6V constrains power supply compatibility. Substitutes must operate within compatible voltage ranges.
• Series Continuity: XBee-Pro® series designation ensures firmware, software, and ecosystem compatibility.
• Regulatory Compliance: REACH status and ECCN classification must be maintained for legal and export compliance.

The XM-M92-2P-UA qualifies as a manufacturer-recommended substitute based on shared XBee-Pro® series lineage, active product status, and compatible RF operating characteristics within the ISM band allocation.

Parameter Comparison

Engineering Selection Recommendations

The XM-M92-2P-UA is designated as the manufacturer-recommended substitute for the obsolete XA-M94-CS2P-A. Selection of this substitute is supported by the following engineering factors:

• Active Product Status: The XM-M92-2P-UA maintains active production and support status, ensuring long-term availability and technical documentation access compared to the obsolete main part.
• Series Continuity: Both components belong to the XBee-Pro® series, providing firmware compatibility and ecosystem consistency within Digi's wireless platform.
• Regulatory Compliance: Both parts maintain REACH Unaffected status and equivalent HTSUS classification (8517.62.0090), ensuring consistent regulatory treatment across procurement and deployment.
• RF Performance Enhancement: The substitute provides improved sensitivity (-110dBm vs. -100dBm) and increased power output (24dBm vs. 18dBm), delivering superior link budget and range performance.
• Frequency Band Alignment: The 902MHz ~ 928MHz operating range of the substitute aligns with the 900MHz ISM band of the main part, maintaining regional regulatory compliance.

Interface and voltage supply differences require system-level evaluation during integration planning.

Frequently Asked Questions (FAQ)

Q: Can the XM-M92-2P-UA directly replace the XA-M94-CS2P-A in existing systems?

A: Direct replacement requires verification of interface compatibility. The main part supports Analog, Digital, RS-232, RS-485, and USB interfaces, while the substitute provides RS-232 only. System designs utilizing Analog, Digital, RS-485, or USB interfaces require interface adapter or redesign consideration.

Q: What are the voltage supply differences between these parts?

A: The XA-M94-CS2P-A operates at 3.7V ~ 6V, while the XM-M92-2P-UA requires 7V ~ 30V. Power supply redesign or regulation circuitry modification is necessary for substitution in systems designed for the lower voltage range.

Q: How do the data rates compare?

A: The main part supports 250kbps maximum data rate, while the substitute operates at 200kbps. Applications requiring data rates above 200kbps cannot use the XM-M92-2P-UA as a substitute.

Q: Are there frequency band compatibility concerns?

A: The main part operates in 900MHz and 2.4GHz ISM bands. The substitute operates in the 902MHz ~ 928MHz range, which overlaps the 900MHz band. Regional regulatory approval for the specific frequency band must be verified for the target deployment region.

Q: What is the packaging difference?

A: The main part packaging is listed as "-" (unspecified). The substitute is supplied in Box packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Why is the main part classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The XM-M92-2P-UA is the active replacement, ensuring continued availability, technical support, and compliance updates.
