Key Parameters

Substitute Part Grouping Explanation

Substitution of the Laird Connectivity 450-0064 is determined by the following critical parameters:

RF Compatibility Requirements:

• Dual mode Bluetooth and WiFi 802.11b/g/n operation
• 2.4GHz frequency band operation
• U.FL antenna connector interface
• Surface mount module packaging

Electrical Performance Criteria:

• Transmit power output of 20dBm
• Receiver sensitivity in the -97dBm to -98dBm range
• Supply voltage compatibility within 2.7V to 4.8V range
• Serial interface support including SDIO and UART

Environmental and Compliance Criteria:

• Operating temperature range spanning -40°C minimum
• ECCN 5A992C classification
• HTSUS 8517.62.0090 tariff code

The ESP32-WROVER-IB qualifies as a substitute based on matching RF standards, frequency band, antenna interface, surface mount configuration, transmit power, receiver sensitivity, and regulatory classifications. Differences in Bluetooth version (v4.2 +EDR versus v4.0), data rate capability (150Mbps versus 65Mbps), and supply voltage range represent functional enhancements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

For Existing System Support: The ESP32-WROVER-IB provides functional equivalence to the obsolete 450-0064 across core RF parameters. Both modules operate in the 2.4GHz band with identical transmit power (20dBm) and comparable receiver sensitivity. The ESP32-WROVER-IB maintains U.FL antenna interface compatibility and surface mount configuration, enabling direct mechanical and electrical integration into existing PCB designs with minimal layout modifications.

Regulatory and Compliance Alignment: Both parts share identical ECCN (5A992C) and HTSUS (8517.62.0090) classifications, ensuring consistent export control and tariff treatment. The ESP32-WROVER-IB holds ROHS3 compliance and REACH Unaffected status, meeting current environmental regulations.

Design Considerations: The ESP32-WROVER-IB operates at a lower maximum supply voltage (3.6V versus 4.8V), requiring verification of power supply design margins. The upper operating temperature limit is reduced to 65°C compared to 85°C for the 450-0064, necessitating thermal analysis for applications in elevated ambient conditions. The ESP32-WROVER-IB provides enhanced serial interface options (GPIO, I2C, PWM, SPI) and higher data rate capability (150Mbps), offering design flexibility for future feature expansion.

Product Status Impact: The 450-0064 is classified as Obsolete, indicating discontinued manufacturing and limited availability. The ESP32-WROVER-IB is classified as Not For New Designs, indicating limited long-term support. For new system development, evaluation of current-generation alternatives is recommended.

Frequently Asked Questions (FAQ)

Q: Can the ESP32-WROVER-IB directly replace the 450-0064 in existing designs?

A: The ESP32-WROVER-IB provides functional equivalence for RF operation, antenna interface, and surface mount configuration. Verification is required for supply voltage compatibility (maximum 3.6V for ESP32-WROVER-IB versus 4.8V for 450-0064) and operating temperature range (maximum 65°C versus 85°C). Serial interface pin assignments must be validated against specific application requirements.

Q: What are the key differences in Bluetooth capability?

A: The 450-0064 implements Bluetooth v4.0 Dual Mode, while the ESP32-WROVER-IB implements Bluetooth v4.2 +EDR with Class 1, 2, and 3 support. Bluetooth v4.2 provides enhanced features and improved interoperability. Both versions support dual mode operation (simultaneous Bluetooth and WiFi).

Q: How do the supply voltage ranges differ?

A: The 450-0064 operates from 3V to 4.8V, while the ESP32-WROVER-IB operates from 2.7V to 3.6V. Systems designed for the 450-0064 with supply voltages above 3.6V require voltage regulation or redesign to accommodate the ESP32-WROVER-IB.

Q: Are there differences in data rate capability?

A: The 450-0064 supports data rates up to 65Mbps, while the ESP32-WROVER-IB supports up to 150Mbps. The higher data rate of the ESP32-WROVER-IB represents a functional enhancement and does not create compatibility issues with existing protocols or applications.

Q: What is the impact of the different operating temperature ranges?

A: The 450-0064 operates from -40°C to 85°C, while the ESP32-WROVER-IB operates from -40°C to 65°C. Applications requiring operation above 65°C ambient temperature cannot use the ESP32-WROVER-IB without thermal management modifications or alternative component selection.

Q: How do the moisture sensitivity levels compare?

A: The 450-0064 has MSL 4 (72 hours), while the ESP32-WROVER-IB has MSL 3 (168 hours). The ESP32-WROVER-IB provides improved moisture tolerance, reducing bake-out requirements and handling constraints during assembly.

Q: Are the antenna connectors identical?

A: Both modules use U.FL antenna connectors with no antenna included. Mechanical and electrical compatibility is maintained, allowing use of the same antenna components and PCB connector footprints.

Q: What serial interfaces are available on each module?

A: The 450-0064 provides I2S, SDIO, and UART interfaces. The ESP32-WROVER-IB provides GPIO, I2C, I2S, PWM, SDIO, SPI, and UART interfaces. The ESP32-WROVER-IB offers additional interface options for enhanced system integration flexibility.
