Key Parameters

Substitute Part Grouping Explanation

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

RF Compatibility Requirements:

• Dual mode Bluetooth and WiFi 802.11b/g/n operation
• 2.4GHz frequency band
• Minimum 20dBm power output capability
• Sensitivity performance within -97dBm to -98dBm range

Interface Compatibility:

• Serial communication via SDIO, UART, and I2S protocols
• U.FL antenna connector for external antenna integration
• Surface mount package configuration

Electrical Specifications:

• Supply voltage overlap within 3V to 4.8V range
• Operating temperature range support from -40°C minimum
• Current consumption profiles for receiving and transmitting modes

Regulatory and Compliance:

• ECCN 5A992C classification
• HTSUS 8517.62.0090 tariff code
• Moisture sensitivity level consideration for assembly processes

The ESP32-WROVER-IB qualifies as a substitute based on matching RF standards, frequency band, power output, antenna interface, mounting type, and regulatory classification. Protocol version advancement (Bluetooth v4.2 +EDR versus v4.0) and enhanced data rate capability (150Mbps versus 65Mbps) represent functional improvements within the same application category.

Engineering Selection Recommendations

Product Status Consideration: The 450-0064R carries Obsolete status, indicating end-of-life designation and unavailability for new procurement. The ESP32-WROVER-IB is classified as Not For New Designs, reflecting a transitional product status. For applications requiring long-term component availability and support, neither part is recommended for new design initiation. However, for replacement or continuation of existing designs, the ESP32-WROVER-IB provides functional equivalence with extended capability.

Regulatory Compliance: Both parts share identical ECCN (5A992C) and HTSUS (8517.62.0090) classifications, ensuring equivalent export control and tariff treatment. The ESP32-WROVER-IB carries RoHS3 compliance and REACH Unaffected status, providing additional regulatory assurance for European market applications.

Electrical Compatibility: Supply voltage ranges differ: the 450-0064R operates from 3V to 4.8V, while the ESP32-WROVER-IB operates from 2.7V to 3.6V. Design implementations must verify that power supply circuits accommodate the narrower voltage window of the substitute part. The maximum operating temperature of the ESP32-WROVER-IB is limited to 65°C compared to 85°C for the main part, requiring thermal analysis for applications in elevated temperature environments.

Interface and Antenna Compatibility: Both modules utilize U.FL antenna connectors and surface mount packaging. The ESP32-WROVER-IB provides expanded serial interface options (GPIO, I2C, I2S, PWM, SDIO, SPI, UART) compared to the 450-0064R (I2S, SDIO, UART), offering greater design flexibility for integration scenarios.

Frequently Asked Questions (FAQ)

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

A: Direct replacement requires verification of three critical factors: (1) Power supply voltage compatibility within the 2.7V to 3.6V range of the ESP32-WROVER-IB, (2) Operating temperature environment not exceeding 65°C maximum, and (3) Serial interface requirements satisfied by the expanded interface set of the substitute part. Physical footprint and pinout compatibility must be confirmed through detailed datasheet comparison.

Q: What are the key differences in wireless protocol capability?

A: The ESP32-WROVER-IB implements Bluetooth v4.2 +EDR with Class 1, 2, and 3 support, compared to Bluetooth v4.0 Dual Mode in the 450-0064R. Both support 802.11b/g/n WiFi standards. The substitute part achieves 150Mbps data rate versus 65Mbps in the main part, representing a 2.3x performance improvement. Sensitivity performance is comparable at -98dBm versus -97dBm.

Q: Are there moisture sensitivity considerations for assembly and storage?

A: The 450-0064R specifies MSL 4 (72 Hours), requiring controlled humidity storage and rapid assembly processing. The ESP32-WROVER-IB specifies MSL 3 (168 Hours), providing more relaxed moisture handling requirements. This represents an improvement in manufacturing process tolerance and storage flexibility.

Q: What is the significance of the product status classifications?

A: Obsolete status for the 450-0064R indicates no further manufacturing or support availability. Not For New Designs status for the ESP32-WROVER-IB indicates the manufacturer recommends against incorporation into new product designs, though existing inventory may be available. For applications requiring component longevity and manufacturer support, alternative current-generation parts should be evaluated.

Q: How do the antenna interface specifications compare?

A: Both modules utilize U.FL connectors with antenna not included in the package. This ensures mechanical and electrical compatibility for external antenna selection and integration. Antenna impedance matching and performance characteristics must be verified independently for each application.

Q: What memory and processing differences exist between these modules?

A: The ESP32-WROVER-IB integrates 448kB ROM and 536kB SRAM, providing on-module memory resources. The 450-0064R memory specifications are not provided in the available data. Applications requiring local processing capability or firmware storage should account for the memory architecture differences between these implementations.
