Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XBP24-AUI-080 is determined by the following critical parameters:

• RF Standard: 802.15.4 compliance is mandatory
• Frequency Band: 2.4GHz operation required
• Data Rate: 250kbps minimum capability
• Modulation Scheme: DSSS modulation required
• Antenna Interface: U.FL connector configuration
• Mounting Configuration: Through-hole package type
• Voltage Supply Compatibility: Operating range must accommodate system voltage requirements
• Temperature Range: Must support -40°C to 85°C operating environment
• Serial Interface: UART support is essential for legacy system integration

The XB3-24Z8UT qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering enhanced performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The XB3-24Z8UT is the qualified substitute for the XBP24-AUI-080 based on the following engineering criteria:

Functional Equivalence: Both modules implement the 802.15.4 standard at 2.4GHz with 250kbps data rate and DSSS modulation. Electrical parameters including frequency, modulation scheme, and antenna interface are identical, ensuring direct functional replacement in existing circuit designs.

Supply Chain Continuity: The XBP24-AUI-080 is classified as obsolete with no ongoing manufacturing. The XB3-24Z8UT maintains active product status with confirmed inventory availability, providing long-term supply assurance for production and support applications.

Regulatory Compliance: Both modules share identical ECCN (5A992C) and HTSUS (8517.62.0090) classifications. The XB3-24Z8UT carries RoHS Compliant certification, meeting current environmental and regulatory requirements. Both modules are REACH Unaffected.

Performance Enhancement: The substitute part delivers improved receiver sensitivity (-103dBm versus -100dBm), increased transmit power (19dBm versus 18dBm), and significantly reduced current consumption during both receive (15mA versus 55mA) and transmit (135mA versus 215mA) operations. These improvements provide enhanced link budget and extended battery life in portable applications.

Interface Compatibility: The XB3-24Z8UT maintains UART serial interface support required for legacy system integration while adding I2C and SPI capabilities for enhanced design flexibility.

Voltage Supply: The XB3-24Z8UT operating range (2.1V ~ 3.6V) encompasses the XBP24-AUI-080 requirement (2.8V ~ 3.4V), ensuring compatibility with existing power supply designs.

Frequently Asked Questions (FAQ)

Q: Can the XB3-24Z8UT directly replace the XBP24-AUI-080 in existing designs?

A: Yes. Both modules implement identical 802.15.4 RF standards, frequency bands, data rates, and modulation schemes. The through-hole mounting configuration and U.FL antenna interface are mechanically identical. UART serial interface compatibility ensures existing firmware and communication protocols function without modification.

Q: What are the key differences between these modules?

A: The XB3-24Z8UT offers improved receiver sensitivity, increased transmit power, and substantially lower current consumption during operation. The substitute part adds I2C and SPI serial interface options and includes 1MB Flash and 128kB RAM memory. The XB3-24Z8UT is RoHS Compliant and maintains active product status.

Q: Are there voltage supply compatibility concerns?

A: No. The XB3-24Z8UT operating range (2.1V ~ 3.6V) fully encompasses the XBP24-AUI-080 specification (2.8V ~ 3.4V). Existing power supply designs require no modification.

Q: What is the packaging difference?

A: The XBP24-AUI-080 packaging specification is not detailed in available data. The XB3-24Z8UT is supplied in Tray packaging. Both modules use identical through-hole mounting configuration.

Q: Does the substitute part support the same operating temperature range?

A: Yes. Both modules operate across -40°C to 85°C, meeting identical environmental specifications.

Q: Are there any protocol differences?

A: The XBP24-AUI-080 operates under the 802.15.4 standard. The XB3-24Z8UT implements 802.15.4 with Zigbee® protocol support. Zigbee® compatibility is a superset of 802.15.4 functionality and does not prevent operation in standard 802.15.4 networks.

Q: What is the impact of reduced current consumption?

A: The XB3-24Z8UT consumes 73% less current during receive operations (15mA versus 55mA) and 37% less during transmit (135mA versus 215mA). This reduction extends battery life in portable applications and reduces thermal dissipation in powered systems.
