CC-WMX-MB69-VM-B Equivalent & Substitute Parts

Part Overview

The CC-WMX-MB69-VM-B is a WiFi 802.11a/b/g/n transceiver module manufactured by Digi as part of the ConnectCore® i.MX51 series. This RF TXRX module operates across 2.4GHz and 5GHz frequency bands with U.FL antenna connector and supports multiple serial interfaces including I2C, SPI, UART, and USB. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CC-WMX-MB69-VM-B is determined by alignment across the following critical parameters:

RF Connectivity & Protocol Compatibility: The substitute must support WiFi 802.11 protocols (minimum 802.11b/g/n coverage). The original part supports 802.11a/b/g/n across 2.4GHz and 5GHz; substitutes operating at 2.4GHz with 802.11b/g/n provide functional equivalence for most applications.

Physical Interface & Antenna: Both parts must use U.FL antenna connectors and surface-mount or module-level packaging to ensure mechanical compatibility.

Serial Communication Interfaces: The substitute must provide I2C, SPI, and UART interfaces as minimum requirements for system integration.

Electrical Characteristics: Power output (19dBm), sensitivity (-94dBm or better), and operating temperature range (-40°C ~ 85°C) establish baseline performance criteria.

Regulatory & Compliance: REACH compliance and ECCN classification must align to ensure regulatory acceptability.

The ATWILC3000-MR110UA from Microchip Technology meets these substitution criteria while offering enhanced Bluetooth v5.0 capability and improved sensitivity (-98dBm).

Parameter Comparison

Engineering Selection Recommendations

The ATWILC3000-MR110UA is the designated manufacturer-recommended substitute for the obsolete CC-WMX-MB69-VM-B. Selection of this substitute is supported by the following factors:

Product Status & Availability: The original part is obsolete with no ongoing manufacturing. The substitute is active production with 3000 units in stock, ensuring supply continuity.

Regulatory Alignment: Both parts share identical ECCN (5A992C) and HTSUS (8517.62.0090) classifications and maintain REACH compliance, eliminating regulatory reclassification requirements.

Core Functionality: The substitute provides WiFi 802.11b/g/n protocol coverage at 2.4GHz, meeting the primary RF connectivity requirements. Enhanced sensitivity (-98dBm vs. -94dBm) and higher data rate (72Mbps vs. 65Mbps) represent performance improvements.

Interface Compatibility: I2C, SPI, and UART interfaces are present on both parts. The original includes USB; the substitute does not. System designs relying on USB connectivity require alternative integration approaches.

Voltage Supply Consideration: The substitute operates at 1.62V ~ 3.6V versus the original's 3.4V ~ 4.8V. Power supply redesign may be necessary for systems designed around the original voltage range.

5GHz Capability Loss: The substitute operates at 2.4GHz only, eliminating 5GHz band support present in the original. Applications requiring dual-band operation require alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the ATWILC3000-MR110UA directly replace the CC-WMX-MB69-VM-B without design changes?

A: Mechanical and RF interface compatibility is established through shared U.FL antenna connectors and module packaging. However, three design considerations apply: (1) USB interface is not available on the substitute; (2) power supply voltage range differs (1.62V ~ 3.6V vs. 3.4V ~ 4.8V); (3) 5GHz band support is not available. Systems designed exclusively for 2.4GHz WiFi with I2C/SPI/UART interfaces and compatible power supplies can implement direct substitution.

Q: What are the key differences in electrical performance?

A: The substitute provides superior sensitivity (-98dBm vs. -94dBm), enabling improved reception in weak signal environments. Data rate is marginally higher (72Mbps vs. 65Mbps). Power output remains equivalent at 19dBm. Current consumption specifications are provided for the substitute (68mA receive, 230mA transmit) but not documented for the original part.

Q: Does the substitute support the same serial interfaces?

A: The substitute provides I2C, SPI, and UART interfaces, matching the original part's core serial communication capability. The original includes USB; the substitute does not. Applications requiring USB connectivity must implement alternative integration methods or select different substitute candidates.

Q: Are there frequency band limitations with the substitute?

A: Yes. The substitute operates exclusively at 2.4GHz, while the original supports both 2.4GHz and 5GHz bands. Applications requiring 5GHz WiFi operation cannot use this substitute and require alternative solutions.

Q: What is the impact of different voltage supply ranges?

A: The substitute requires 1.62V ~ 3.6V supply versus the original's 3.4V ~ 4.8V. Systems designed for the original part's higher voltage range require power supply redesign or voltage regulation modification to operate the substitute within its specified voltage window.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both parts share identical ECCN (5A992C) and HTSUS (8517.62.0090) classifications and maintain REACH compliance status. No regulatory reclassification is required for substitution.

Q: What is the packaging difference between these parts?

A: The original is specified as a Module; the substitute is specified as Surface Mount. Both are module-level components with U.FL connectors. The substitute is supplied in Tray packaging (3000 units in stock) versus the original's unspecified packaging format.
