XB24CDMPIT-001 Equivalent & Substitute Parts

Part Overview

The XB24CDMPIT-001 is a General ISM > 1GHz Transceiver Module from Digi's XBee® DigiMesh® 2.4 series, designed for 2.4GHz wireless communication applications. This module integrates a trace antenna and operates through a Through Hole mounting configuration. The product is classified as Not For New Designs, indicating that Digi has transitioned this model away from active development. For new system designs or when XB24CDMPIT-001 inventory becomes unavailable, identifying compatible substitute modules with equivalent electrical and mechanical characteristics is essential for maintaining design flexibility and ensuring long-term supply chain viability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XB24CDMPIT-001 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 2.4GHz
• Modulation: DSSS
• Data Rate: 250kbps
• Mounting Type: Through Hole
• Antenna Type: Integrated, Trace
• Package / Case: Module
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Compliance: RoHS Compliant

Allowable Variation Parameters:

• RF Family/Standard: May differ (General ISM > 1GHz vs. 802.15.4) provided core wireless performance is maintained
• Power Output: ±1dBm tolerance acceptable
• Sensitivity: ±1dBm improvement acceptable
• Voltage Supply Range: May have lower minimum threshold if maximum remains ≥3.6V
• Current Consumption: May be lower in receive and transmit modes
• Serial Interfaces: May include additional interfaces (I2C addition acceptable)
• Utilized IC / Part: May differ based on manufacturer design evolution
• Memory Size: May be expanded
• Product Status: Active status preferred for new designs

The XB3-24Z8PT-J meets all mandatory matching parameters and demonstrates acceptable variation in allowable parameters, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The XB3-24Z8PT-J is a qualified substitute for the XB24CDMPIT-001 based on the following engineering criteria:

Compliance & Certification Alignment: Both modules maintain RoHS Compliance and identical ECCN (5A992C) and HTSUS (8517.62.0090) classifications, ensuring regulatory equivalence for procurement and export purposes.

Product Status Advantage: The XB3-24Z8PT-J carries Active product status, whereas the XB24CDMPIT-001 is designated Not For New Designs. This distinction makes the XB3-24Z8PT-J the preferred choice for new system development, as it ensures continued manufacturer support, availability, and potential firmware updates.

Electrical Performance: The XB3-24Z8PT-J demonstrates equivalent or superior electrical characteristics: identical output power (8dBm), improved sensitivity (-103dBm vs. -102dBm), reduced current consumption in both receive (15mA vs. 31mA) and transmit (40mA vs. 45mA) modes, and expanded voltage supply compatibility (2.1V minimum vs. 2.7V minimum). These improvements provide design flexibility and enhanced power efficiency.

Mechanical & Functional Compatibility: Both modules share identical mounting type (Through Hole), antenna configuration (Integrated, Trace), package form factor (Module), and operating temperature range (-40°C ~ 85°C), ensuring direct mechanical and thermal compatibility in existing PCB designs.

Interface Expansion: The XB3-24Z8PT-J adds I2C serial interface capability while retaining SPI and UART interfaces present in the original module, providing enhanced system integration options without compromising existing interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the XB3-24Z8PT-J be used as a direct replacement for the XB24CDMPIT-001 in existing designs?

A: Yes. Both modules share identical frequency (2.4GHz), data rate (250kbps), modulation (DSSS), mounting type (Through Hole), antenna type (Integrated, Trace), and operating temperature range (-40°C ~ 85°C). The XB3-24Z8PT-J maintains all required electrical specifications and improves upon power consumption and sensitivity characteristics.

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

A: The primary differences are: (1) RF Family/Standard classification (General ISM > 1GHz vs. 802.15.4 Zigbee®), (2) Product Status (Not For New Designs vs. Active), (3) Utilized IC (EM357 vs. EFR32MG), (4) Memory capacity (XB3-24Z8PT-J includes 1MB Flash and 128kB RAM), (5) Receive current consumption (15mA vs. 31mA), (6) Transmit current consumption (40mA vs. 45mA), and (7) Serial interface options (addition of I2C in XB3-24Z8PT-J).

Q: Are there any voltage supply compatibility concerns?

A: No. The XB3-24Z8PT-J operates across 2.1V ~ 3.6V, which encompasses the original module's 2.7V ~ 3.6V range. Systems designed for the XB24CDMPIT-001 will operate without modification. The expanded lower voltage limit provides additional design flexibility for battery-powered applications.

Q: Will the addition of I2C interface on the XB3-24Z8PT-J cause compatibility issues?

A: No. The XB3-24Z8PT-J retains the SPI and UART interfaces required by the original XB24CDMPIT-001. The I2C interface is an additional capability that does not interfere with existing interface implementations. Designs using only SPI and UART will function identically.

Q: Are both modules RoHS compliant?

A: Yes. Both the XB24CDMPIT-001 and XB3-24Z8PT-J are RoHS Compliant and share identical regulatory classifications (ECCN: 5A992C, HTSUS: 8517.62.0090), ensuring equivalent compliance status for procurement and international distribution.

Q: Why is the XB24CDMPIT-001 marked as Not For New Designs?

A: This designation indicates that Digi has concluded the active development phase for this product line and recommends the XB3-24Z8PT-J (from the XBee® 3 Zigbee 3 series) for new system designs. The XB3-24Z8PT-J provides enhanced capabilities, improved power efficiency, and assured long-term manufacturer support.

Q: What is the inventory status for these modules?

A: The XB24CDMPIT-001 has 1859 pieces available as new original stock. The XB3-24Z8PT-J has 18223 pieces available as new original stock, indicating significantly higher availability for immediate procurement.
