CC3000MODR Equivalent & Substitute Parts

Part Overview

The CC3000MODR is a WiFi 802.11b/g transceiver module manufactured by Texas Instruments as part of the SimpleLink™ series. This surface mount RF module integrates a 2.4GHz transceiver with support for CCK, DSSS, and OFDM modulation standards. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support, redesigns, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CC3000MODR are identified based on the following critical parameters:

Mandatory Compatibility Criteria:

• Manufacturer: Texas Instruments
• Series: SimpleLink™
• RF Standard: WiFi 2.4GHz
• Mounting Type: Surface Mount
• Package Type: Module (63-SMD configuration)
• Serial Interfaces: Support for I2C, SPI, and/or UART

Substitution Logic: The CC3100MODR11MAMOBR and CC3120MODRNMMOBR are qualified substitutes because they maintain the same RF family, frequency band, and module-level integration. Both parts operate within compatible voltage ranges and support the same serial communication protocols. The CC3120MODRNMMOBR offers extended operating temperature range (-40°C to 85°C) and improved RoHS3 compliance, making it suitable for applications requiring broader environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

CC3100MODR11MAMOBR Selection Criteria: This substitute is appropriate for applications with standard operating temperature requirements (-20°C to 70°C) and where SPI interface is the primary communication protocol. The part achieves ROHS3 compliance and maintains active product status with 1940 units in stock. Current consumption is reduced compared to the CC3000MODR, particularly in receive mode (54mA vs. 92mA).

CC3120MODRNMMOBR Selection Criteria: This substitute is recommended for applications requiring extended operating temperature range (-40°C to 85°C) or where I2C and UART interfaces are necessary alongside SPI. The CC3120MODRNMMOBR maintains full protocol support (802.11b/g/n) and achieves ROHS3 compliance. Significantly higher inventory availability (89,188 units) supports production scalability. Current consumption remains comparable to the CC3100MODR while supporting a broader interface set.

Both substitutes operate within the 2.4GHz WiFi band and maintain module-level integration compatible with existing PCB layouts designed for 63-SMD configurations.

Frequently Asked Questions (FAQ)

Q: Can the CC3100MODR11MAMOBR directly replace the CC3000MODR in existing designs? A: Direct replacement requires verification of serial interface requirements. The CC3100MODR11MAMOBR supports only SPI, whereas the CC3000MODR supports I2C, SPI, and UART. If the design uses I2C or UART, the CC3120MODRNMMOBR is the appropriate substitute.

Q: What are the key differences between the two substitute parts? A: The CC3100MODR11MAMOBR is optimized for standard temperature ranges and SPI-only applications. The CC3120MODRNMMOBR extends operating temperature to -40°C to 85°C and supports all three serial interfaces (I2C, SPI, UART), providing greater design flexibility.

Q: Are both substitute parts RoHS compliant? A: Yes. Both CC3100MODR11MAMOBR and CC3120MODRNMMOBR achieve ROHS3 compliance, whereas the original CC3000MODR is RoHS non-compliant.

Q: What is the impact of the voltage supply range difference? A: The CC3000MODR operates from 1.8V to 3.6V, while both substitutes operate from 2.3V to 3.6V. Designs operating below 2.3V require circuit modification or retention of the original part.

Q: How do the modulation standards differ? A: The CC3000MODR supports CCK, DSSS, and OFDM modulation. The CC3100MODR11MAMOBR and CC3120MODRNMMOBR support 802.11b/g/n protocols with DSSS and OFDM modulation, providing enhanced data rates and backward compatibility.

Q: What is the MSL rating significance for these modules? A: The CC3000MODR has MSL 4 (72-hour shelf life after moisture exposure). Both substitutes have MSL 3 (168-hour shelf life), allowing longer storage periods and reducing production constraints.
