Key Parameters

Substitute Part Grouping Explanation

Substitution of the CC-WMX-MB69-VK-B is determined by the following critical parameters:

RF Capability Match: The substitute must support WiFi protocol operation. The ATWILC3000-MR110UA provides WiFi 802.11b/g/n support, covering the primary 2.4GHz band utilized by the original module.

Frequency Band Alignment: The original module operates at 2.4GHz and 5GHz. The substitute operates at 2.4GHz, which covers the primary operational band for most WiFi applications.

Output Power and Sensitivity: Both modules deliver 19dBm output power. The substitute provides -98dBm sensitivity compared to the original -94dBm, representing improved receiver performance.

Serial Interface Compatibility: The original module provides I2C, SPI, UART, and USB interfaces. The substitute provides I2C, SPI, and UART interfaces, covering the primary control and data pathways.

Antenna Configuration: Both modules use U.FL connectors with antenna not included, ensuring mechanical and RF compatibility.

Operating Temperature Range: Both modules operate across -40°C to 85°C, maintaining thermal compatibility.

Supply Voltage: The original requires 3.4V to 4.8V; the substitute operates at 1.62V to 3.6V. The substitute's lower voltage range requires verification of power supply compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

The ATWILC3000-MR110UA is an active product from Microchip Technology with current manufacturing support and inventory availability. Both modules share identical ECCN classification (5A992C) and REACH compliance status, ensuring regulatory alignment for export and environmental requirements.

The substitute provides improved receiver sensitivity (-98dBm versus -94dBm) and higher data rate capability (72Mbps versus 65Mbps). However, the substitute operates at reduced supply voltage (1.62V to 3.6V versus 3.4V to 4.8V), requiring verification that existing power supply designs can accommodate this lower voltage range.

The original module supports USB interface; the substitute provides only I2C, SPI, and UART. Applications requiring USB connectivity must implement alternative communication pathways or select a different substitute.

The substitute includes Bluetooth v5.0 capability in addition to WiFi, providing extended functionality for dual-mode wireless applications. The substitute is surface-mount configured, whereas the original mounting type is not specified.

Moisture sensitivity differs between modules: the original has MSL 1 (unlimited shelf life), while the substitute has MSL 3 (168-hour limit), affecting storage and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the ATWILC3000-MR110UA directly replace the CC-WMX-MB69-VK-B in existing designs?

A: Direct replacement requires verification of three factors: (1) power supply compatibility with the lower voltage range of 1.62V to 3.6V, (2) absence of USB interface dependency in the original design, and (3) PCB layout accommodation for surface-mount configuration. The U.FL antenna connector and operating temperature range are compatible.

Q: What is the primary difference in RF capability between these modules?

A: The original CC-WMX-MB69-VK-B supports 802.11a/b/g/n across 2.4GHz and 5GHz bands. The ATWILC3000-MR110UA supports 802.11b/g/n at 2.4GHz only, eliminating 5GHz capability. Applications requiring 5GHz operation cannot use this substitute.

Q: How do the serial interfaces differ?

A: The original module provides I2C, SPI, UART, and USB. The substitute provides I2C, SPI, and UART. If the design uses USB for communication or firmware updates, alternative methods must be implemented with the substitute.

Q: What are the implications of different moisture sensitivity levels?

A: The original module (MSL 1) has unlimited shelf life under standard storage conditions. The substitute (MSL 3) requires use within 168 hours of moisture barrier bag opening. This affects inventory management, storage procedures, and component handling protocols.

Q: Are both modules compliant with the same export regulations?

A: Yes. Both modules carry identical ECCN classification (5A992C) and REACH Unaffected status, ensuring equivalent regulatory treatment for export control and environmental compliance purposes.

Q: What is the data rate difference between these modules?

A: The original supports 65Mbps; the substitute supports 72Mbps. The substitute provides higher throughput capability for WiFi data transmission.

Q: How do power consumption characteristics compare?

A: The original module does not specify receive or transmit current. The substitute specifies 68mA receive current and 230mA transmit current, enabling power budget calculations for battery-powered or power-constrained applications.
