Acceptable Variations:

• Protocol support may extend beyond Zigbee® to include additional standards (Bluetooth, Thread)
• Data rate may exceed 250kbps
• Power output may differ within the 2.4GHz band
• Sensitivity specifications may vary
• Supply voltage range may be broader
• Current consumption may differ
• Serial interface sets may include additional interfaces
• Utilized IC may differ provided RF performance parameters are met

The substitute parts 451-00001 and 453-00020R both maintain core 802.15.4 compatibility at 2.4GHz with integrated trace antennas and surface mount construction, supporting the same operating temperature range and RoHS compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

For 451-00001 (Laird Connectivity BL654):

The 451-00001 is an Active product with current manufacturing support. It maintains 802.15.4 compatibility while extending protocol support to Bluetooth v5.0 and Thread. The part operates within the same temperature range (-40°C ~ 85°C) and carries identical RoHS compliance and MSL ratings. The 451-00001 utilizes the nRF52840 IC and provides a broader serial interface set (I2C, I2S, PWM, SPI, UART, USB). Supply voltage range is expanded (1.7V ~ 3.6V), and current consumption is significantly reduced during both receive (5.4mA vs. 30mA) and transmit (14.1mA vs. 149mA) operations. Power output is reduced to 8dBm. This substitute is suitable for applications where the 802.15.4 protocol requirement is maintained and lower power consumption is beneficial.

For 453-00020R (Laird Connectivity PCB Trace Module):

The 453-00020R is an Active product with current manufacturing support. Limited technical parameters are provided in the specification. The part utilizes the nRF52840 IC and features PCB trace antenna configuration. It maintains RoHS compliance and MSL rating 4 (72 Hours). This substitute requires detailed specification review before implementation to confirm compatibility with the 450-0075 application requirements.

Both substitute parts carry Active product status, ensuring ongoing availability and manufacturing support compared to the Obsolete 450-0075.

Frequently Asked Questions (FAQ)

Q: Can the 451-00001 directly replace the 450-0075 in existing designs?

A: The 451-00001 maintains 802.15.4 protocol support at 2.4GHz with integrated trace antenna and surface mount construction. However, differences exist in power output (8dBm vs. 20dBm), current consumption, and utilized IC (nRF52840 vs. CC2520). Design verification is required to confirm compatibility with specific application requirements, particularly regarding RF performance and power budget.

Q: What are the key differences in power consumption between the 450-0075 and 451-00001?

A: The 451-00001 demonstrates significantly lower current consumption: 5.4mA during receive operations compared to 30mA for the 450-0075, and 14.1mA during transmit compared to 149mA. This reduction may impact battery life in portable applications but requires verification that the lower power output (8dBm) meets link budget requirements.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both 451-00001 and 453-00020R carry RoHS Compliant status with identical MSL rating 4 (72 Hours) and ECCN/HTSUS classifications as the 450-0075.

Q: What is the difference between the antenna configurations?

A: The 450-0075 and 451-00001 both feature integrated trace antenna design. The 453-00020R specifies PCB trace antenna configuration. Antenna design impacts RF performance and PCB layout requirements.

Q: What supply voltage range should be used for the 451-00001?

A: The 451-00001 operates across 1.7V ~ 3.6V, which is broader than the 450-0075 range of 2V ~ 3.3V. Designs using the 450-0075 at 2V ~ 3.3V are compatible with the 451-00001 within this overlapping range.

Q: Are the serial interfaces compatible between the 450-0075 and 451-00001?

A: Both parts support I2C, SPI, and UART interfaces. The 451-00001 provides additional interfaces (I2S, PWM, USB) not present in the 450-0075. Existing designs using I2C, SPI, or UART are compatible; additional interfaces on the 451-00001 are optional.

Q: What is the packaging difference between these parts?

A: The 450-0075 is specified as Module package type. The 451-00001 is specified as 72-SMD Module with Tape & Reel (TR) packaging. The 453-00020R packaging details are not fully specified. PCB footprint and assembly process verification is required.
