Key Parameters

Substitute Part Grouping Explanation

Substitution of the XB8-DMPSB002 is determined by strict equivalence across the following critical parameters:

• RF Family and Frequency: Both parts must operate in the General ISM < 1GHz band at 868MHz
• Data Rate: 80kbps operation maintained
• RF Performance: Power output (14dBm) and sensitivity (-101dBm) specifications
• Antenna Configuration: Integrated trace antenna required
• Utilized IC: ADF7023 chipset
• Voltage Supply Range: 2.7V ~ 3.6V compatibility
• Mounting and Package: Surface mount module form factor
• Environmental Compliance: Operating temperature range -40°C ~ 85°C and MSL rating

The XB8-DMRS-002 meets all these criteria as a direct functional equivalent within the XBee® 868LP series.

Engineering Selection Recommendations

The XB8-DMRS-002 is the direct substitute for the obsolete XB8-DMPSB002. Selection is based on the following engineering factors:

• Product Status: XB8-DMRS-002 is active and currently manufactured, ensuring supply chain continuity and long-term availability
• Regulatory Compliance: XB8-DMRS-002 carries RoHS Compliant certification, meeting current environmental standards
• Electrical Equivalence: All RF performance parameters, frequency, data rate, power output, and sensitivity specifications are identical
• Power Efficiency: XB8-DMRS-002 demonstrates reduced current consumption in both receive (27mA vs 41mA) and transmit (48mA vs 62mA) modes, providing improved power efficiency for battery-operated applications
• Form Factor and Interface: Identical surface mount module packaging and electrical interface ensure direct PCB compatibility without redesign

Frequently Asked Questions (FAQ)

Q: Can XB8-DMRS-002 be used as a direct replacement for XB8-DMPSB002 without PCB modifications?

A: Yes. Both parts are surface mount modules with identical package types, electrical interfaces, voltage supply ranges (2.7V ~ 3.6V), and operating temperature specifications (-40°C ~ 85°C). No PCB layout changes are required.

Q: Are the RF performance characteristics identical between these parts?

A: Yes. Both operate at 868MHz in the General ISM < 1GHz band with identical data rate (80kbps), power output (14dBm), sensitivity (-101dBm), and antenna configuration (integrated trace antenna). Both utilize the ADF7023 IC.

Q: What is the difference in current consumption?

A: XB8-DMRS-002 operates at lower current levels: 27mA receive (vs 41mA) and 48mA transmit (vs 62mA). This represents improved power efficiency and is beneficial for power-constrained applications.

Q: Why is XB8-DMPSB002 listed as obsolete?

A: XB8-DMPSB002 has been discontinued by the manufacturer. XB8-DMRS-002 is the active production equivalent and is the recommended part for all new designs and field replacements.

Q: Are there any compliance differences?

A: XB8-DMRS-002 is certified RoHS Compliant. Both parts maintain identical REACH Unaffected status and ECCN/HTSUS classifications. Both carry MSL rating 3 (168 Hours).

Q: What is the packaging difference?

A: XB8-DMPSB002 was supplied in standard packaging, while XB8-DMRS-002 is supplied in bulk packaging. This does not affect electrical or mechanical compatibility.
