Key Parameters

Substitute Part Grouping Explanation

Substitution of the XA-M94-CE1P-A is determined by the following critical parameters:

Frequency Band Compatibility: The main part operates in the 900MHz and 2.4GHz ISM bands. Substitute parts must support the 900MHz band to maintain system compatibility.

Interface Requirements: The original adapter provides multiple interface options (Analog, Digital, RS-232, RS-485, USB). Substitute parts must provide equivalent connectivity, with USB being a primary interface consideration.

Modulation Protocol: The main part uses ISM modulation. Substitute parts employing FHSS (Frequency Hopping Spread Spectrum) in the 900MHz band are functionally equivalent for ISM applications.

Data Rate: The original part supports 250kbps maximum data rate. Substitute parts with comparable or higher data rates maintain functional equivalence.

Power Characteristics: Supply voltage and output power must remain within acceptable ranges for system integration.

Product Status and Compliance: Active product status with current certifications ensures ongoing availability and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The XM-M92-UP-UA serves as the manufacturer-recommended substitute for the obsolete XA-M94-CE1P-A. Both components are part of the XBee-Pro® series from Digi and share the same Moisture Sensitivity Level classification.

The substitute part operates within the 902MHz to 928MHz frequency range, which overlaps with the 900MHz band of the original part. The FHSS modulation protocol employed by the XM-M92-UP-UA is compatible with ISM band applications.

The XM-M92-UP-UA provides improved receiver sensitivity (-110dBm versus -100dBm) and higher output power (24dBm versus 18dBm). However, the maximum data rate is reduced to 200kbps compared to the original 250kbps specification.

The substitute part features USB interface exclusively, whereas the original adapter provided multiple interface options. System designs requiring RS-232, RS-485, or Analog interfaces must evaluate additional interface conversion requirements.

The substitute part is RoHS Compliant and maintains Active product status, ensuring continued availability and regulatory compliance. The supply voltage range differs (2.1V ~ 3.6V for the substitute versus 3.7V ~ 6V for the original), requiring verification of power supply compatibility in existing systems.

Frequently Asked Questions (FAQ)

Q: Can the XM-M92-UP-UA directly replace the XA-M94-CE1P-A in existing systems?

A: Direct replacement depends on interface requirements. Both parts operate in the 900MHz ISM band and share the XBee-Pro® series compatibility. However, the substitute part provides USB interface only, whereas the original adapter includes RS-232, RS-485, and Analog interfaces. Systems relying on these additional interfaces require supplementary conversion components.

Q: What is the frequency band compatibility between these parts?

A: The XA-M94-CE1P-A operates at 900MHz and 2.4GHz. The XM-M92-UP-UA operates at 902MHz to 928MHz. The 900MHz band of the original part falls within the 902MHz to 928MHz range of the substitute, providing frequency band overlap for 900MHz ISM applications.

Q: How do the data rates compare?

A: The original XA-M94-CE1P-A supports a maximum data rate of 250kbps. The substitute XM-M92-UP-UA supports 200kbps. Applications requiring the full 250kbps data rate must evaluate whether the reduced rate impacts system performance.

Q: What are the power supply differences?

A: The XA-M94-CE1P-A requires 3.7V to 6V supply voltage. The XM-M92-UP-UA requires 2.1V to 3.6V. Existing power supplies designed for the original part may exceed the maximum voltage specification of the substitute. Power supply compatibility must be verified before implementation.

Q: Are there packaging differences?

A: The XA-M94-CE1P-A packaging is specified as "-" (not detailed). The XM-M92-UP-UA is supplied in Box packaging. Mechanical integration and form factor compatibility should be evaluated for specific applications.

Q: What is the significance of the product status difference?

A: The XA-M94-CE1P-A is classified as Obsolete, indicating discontinued manufacturing and limited availability. The XM-M92-UP-UA is classified as Active, ensuring ongoing production, availability, and manufacturer support. New designs should prioritize the active substitute part.
