Mandatory Matching Parameters:

• RF Family/Standard: General ISM < 1GHz
• Frequency: 868MHz
• Antenna Type: U.FL connector configuration
• Utilized IC: ADF7023
• Memory Configuration: 32kB Flash, 2kB RAM
• Voltage Supply Range: 2.7V ~ 3.6V
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C
• Package/Case: Module

Allowable Parameter Variations:

• Data Rate: May increase from 10kbps to higher rates while maintaining backward compatibility
• Power Output: Remains constant at 14dBm
• Sensitivity: May improve (lower dBm values) from -106dBm
• Current Consumption: May vary within operational specifications
• Packaging Format: May change from standard to Tray
• Product Status: Active alternatives preferred over obsolete status

The XB8-DMUSB002 qualifies as a direct substitute based on identical RF characteristics, frequency, antenna interface, core IC, memory configuration, voltage supply, and thermal operating range.

Engineering Selection Recommendations

The XB8-DMUSB002 is the qualified substitute for the obsolete XB8-DMUSB001. Selection is based on the following engineering criteria:

Product Status: The XB8-DMUSB002 maintains Active product status, ensuring continued manufacturer support, availability, and compliance updates. The XB8-DMUSB001 is Obsolete, limiting future procurement options and technical support.

Regulatory Compliance: The XB8-DMUSB002 is RoHS Compliant with ECCN classification 5A992C and HTSUS code 8517.62.0090, meeting current environmental and export control requirements. The XB8-DMUSB001 carries an Obsolete ECCN designation.

Functional Compatibility: Both modules share identical RF characteristics, frequency band, antenna interface, core IC architecture, memory configuration, voltage supply range, and thermal operating specifications. The XB8-DMUSB002 offers enhanced data rate capability (80kbps versus 10kbps) and improved receiver sensitivity (-101dBm versus -106dBm), providing performance headroom for existing applications.

Packaging: The XB8-DMUSB002 is supplied in Tray packaging format, standard for production environments. Both modules employ identical Surface Mount technology and Module package configuration.

Frequently Asked Questions (FAQ)

Q: Can the XB8-DMUSB002 directly replace the XB8-DMUSB001 in existing designs?

A: Yes. The XB8-DMUSB002 is electrically and mechanically compatible with the XB8-DMUSB001. Both modules operate at 868MHz, share identical voltage supply requirements (2.7V ~ 3.6V), current consumption specifications, thermal operating range (-40°C ~ 85°C), and U.FL antenna interface. Surface mount footprints and module dimensions are identical.

Q: What are the key differences between these two parts?

A: The primary differences are product status and performance characteristics. The XB8-DMUSB002 is Active with RoHS compliance, while the XB8-DMUSB001 is Obsolete. The XB8-DMUSB002 provides higher data rate (80kbps versus 10kbps) and improved receiver sensitivity (-101dBm versus -106dBm). Current consumption and power output remain identical.

Q: Are there any compatibility concerns with the higher data rate of the XB8-DMUSB002?

A: No compatibility concerns exist. The higher data rate of the XB8-DMUSB002 is a performance enhancement. Applications designed for the 10kbps data rate of the XB8-DMUSB001 operate without modification on the XB8-DMUSB002. The substitute part maintains backward compatibility with existing firmware and protocol implementations.

Q: What is the packaging difference between these modules?

A: The XB8-DMUSB001 uses standard packaging, while the XB8-DMUSB002 is supplied in Tray format. Both employ identical Surface Mount technology and Module package configuration. Tray packaging is standard for production environments and does not affect electrical or mechanical performance.

Q: Are both modules suitable for the same operating temperature range?

A: Yes. Both the XB8-DMUSB001 and XB8-DMUSB002 operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility in all environmental conditions.

Q: What regulatory certifications apply to the XB8-DMUSB002?

A: The XB8-DMUSB002 is RoHS Compliant and REACH Unaffected. It carries ECCN classification 5A992C and HTSUS code 8517.62.0090. These certifications meet current environmental and export control requirements for RF transceiver modules.
