Key Parameters

Substitute Part Grouping Explanation

Substitution of the XB24-Z7CIT-002 is determined by the following critical parameters:

• RF standard compliance (802.15.4 Zigbee®)
• Operating frequency (2.4GHz)
• Mounting type (Through Hole)
• Supply voltage range (2.1V ~ 3.6V)
• Operating temperature range (-40°C ~ 85°C)
• Serial interface capability (UART minimum requirement)

The identified substitute XB24CZ7PIT-004 maintains compatibility across these core parameters while offering enhanced performance characteristics and improved product status for new design applications.

Parameter Comparison

Engineering Selection Recommendations

The XB24CZ7PIT-004 serves as the manufacturer-recommended substitute for the obsolete XB24-Z7CIT-002. Both modules maintain identical supply voltage ranges and operating temperature specifications, ensuring thermal and power compatibility in existing system designs.

The XB24CZ7PIT-004 provides enhanced RF performance with increased data rate (1Mbps vs. 250kbps), improved sensitivity (-102dBm vs. -96dBm), and higher transmit power (8dBm vs. 1dBm). The substitute adds SPI interface capability alongside UART, expanding integration flexibility.

The XB24CZ7PIT-004 achieves RoHS Compliance status, whereas the original part does not specify compliance. Both modules maintain REACH Unaffected status. The substitute's "Not For New Designs" classification indicates limited long-term availability; however, it remains the direct functional equivalent for legacy system maintenance and component replacement.

Frequently Asked Questions (FAQ)

Q: Can XB24CZ7PIT-004 directly replace XB24-Z7CIT-002 in existing designs?

A: Yes. Both modules operate on identical supply voltage (2.1V ~ 3.6V), temperature range (-40°C ~ 85°C), and maintain 802.15.4 Zigbee® protocol compliance. Through-hole mounting is identical. UART interface compatibility is maintained. The substitute's enhanced performance characteristics do not create backward compatibility issues.

Q: What are the key performance differences?

A: The XB24CZ7PIT-004 provides higher data rate (1Mbps vs. 250kbps), improved receiver sensitivity (-102dBm vs. -96dBm), and increased transmit power (8dBm vs. 1dBm). These enhancements improve link budget and throughput without affecting pin compatibility or protocol operation.

Q: Does antenna type difference affect substitution?

A: Both modules feature integrated antennas. The XB24-Z7CIT-002 uses chip antenna design while XB24CZ7PIT-004 uses trace antenna design. Both are integrated solutions requiring no external antenna components. Trace antenna design in the substitute may provide marginal performance improvement in certain RF environments.

Q: Are there packaging differences?

A: The XB24-Z7CIT-002 uses standard module packaging. The XB24CZ7PIT-004 is supplied in Tray packaging. Both maintain identical through-hole mounting footprint and pin configuration.

Q: What is the significance of product status classifications?

A: XB24-Z7CIT-002 is classified as Obsolete, indicating discontinued production and limited availability. XB24CZ7PIT-004 is classified as Not For New Designs, indicating restricted availability for new applications but continued support for existing systems. For legacy system maintenance, XB24CZ7PIT-004 represents the current manufacturer-supported equivalent.
