Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MRF24WG0MAT-I/RM are selected based on the following critical parameters:

• RF standard and protocol compatibility (WiFi 802.11b/g minimum support)
• Operating frequency (2.4GHz)
• Integrated trace antenna configuration
• Surface mount packaging
• Industrial temperature range (-40°C to 85°C)
• RoHS3 compliance and REACH unaffected status
• Voltage supply range overlap or compatibility

The two substitute parts identified—ATWILC1000-MR110PB and ATWINC1500-MR210PB—both meet these core substitution criteria while offering enhanced protocol support (802.11b/g/n) and improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Microchip Technology and maintain active product status, ensuring long-term availability and support. Both ATWILC1000-MR110PB and ATWINC1500-MR210PB are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original MRF24WG0MAT-I/RM.

ATWINC1500-MR210PB provides the closest voltage supply range alignment (2.7V ~ 3.6V) with the original part, minimizing power supply redesign requirements. This part also includes onboard memory (4MB Flash, 128kB RAM) and supports firmware version 19.4.4.

ATWILC1000-MR110PB offers the lowest receiving current consumption (29mA ~ 68mA) compared to the original part's 156mA, providing power efficiency advantages in battery-operated applications. However, its voltage supply range (3.3V ~ 4.3V) requires power supply adjustment from the original specification.

Both substitute parts support enhanced 802.11b/g/n protocols with improved data rates (72.2Mbps) and sensitivity performance (-98dBm for ATWILC1000-MR110PB), providing functional improvements over the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can ATWILC1000-MR110PB and ATWINC1500-MR210PB be used interchangeably with MRF24WG0MAT-I/RM?

A: Both parts meet the core substitution criteria of 2.4GHz WiFi operation with integrated trace antennas and surface mount packaging. However, they differ in voltage supply ranges and current consumption profiles. Direct substitution requires verification of power supply compatibility and interface requirements in the target application.

Q: What are the key differences in voltage supply requirements?

A: The original MRF24WG0MAT-I/RM operates at 2.8V ~ 3.6V. ATWINC1500-MR210PB maintains compatibility within 2.7V ~ 3.6V. ATWILC1000-MR110PB requires 3.3V ~ 4.3V, necessitating power supply redesign if used as a substitute.

Q: How do the substitute parts improve upon the original design?

A: Both substitute parts support 802.11b/g/n protocols versus the original 802.11b/g, enabling higher data rates (72.2Mbps versus 54Mbps). ATWILC1000-MR110PB provides significantly reduced receiving current (29mA ~ 68mA versus 156mA). ATWINC1500-MR210PB includes integrated memory and firmware support.

Q: Are there packaging differences between these parts?

A: MRF24WG0MAT-I/RM uses a 36-SMD module package. ATWILC1000-MR110PB uses a 28-SMD module with exposed pad. ATWINC1500-MR210PB uses a module package. PCB layout modifications may be required due to different pin configurations and package dimensions.

Q: Do all parts meet the same regulatory and compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. ECCN and HTSUS classifications are consistent across all parts, meeting export and import regulatory requirements.
