ATZB-24-A2R Equivalent & Substitute Parts

Part Overview

The ATZB-24-A2R is an 802.15.4 Zigbee transceiver module manufactured by Microchip Technology, designed for 2.4GHz wireless communication applications. This chip surface mount module integrates the AT86RF230 IC and provides complete RF transmission and reception capabilities for Zigbee protocol implementations. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support, redesigns, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATZB-24-A2R is determined by the following core parameters:

• RF standard compliance (802.15.4)
• Operating frequency (2.4GHz)
• Data rate (250kbps)
• Mounting type (Surface Mount)
• Package configuration (PCB Module)
• Supply voltage compatibility
• RoHS compliance status

The ENW-C9A02A3E from Panasonic Electronic Components qualifies as a substitute based on matching RF standard, frequency, data rate, mounting type, package type, and RoHS compliance. Differences in sensitivity, current consumption, and temperature range represent trade-offs within the 802.15.4 transceiver module category but do not preclude functional substitution when system requirements permit.

Parameter Comparison

Engineering Selection Recommendations

The ENW-C9A02A3E represents an active product alternative to the obsolete ATZB-24-A2R. Both components maintain ROHS3 compliance and support the 802.15.4 standard at 2.4GHz with 250kbps data rate. The Panasonic module offers extended operating temperature range (-40°C to 85°C versus -20°C to 70°C) and active product status, ensuring continued availability and manufacturer support.

Design considerations for substitution include the reduced sensitivity specification (-97dBm versus -101dBm), higher current consumption during receive and transmit operations, and narrower supply voltage minimum (2.1V versus 1.8V). The ENW-C9A02A3E omits JTAG and USART interfaces present in the original design; systems dependent on these interfaces require architectural review.

Frequently Asked Questions (FAQ)

Q: Can the ENW-C9A02A3E directly replace the ATZB-24-A2R in existing designs?

A: Direct replacement is possible for applications where the reduced sensitivity (-97dBm), higher current consumption, and narrower voltage range (2.1V minimum) are acceptable. Systems utilizing JTAG or USART interfaces require interface redesign.

Q: What is the primary reason for seeking substitutes for the ATZB-24-A2R?

A: The ATZB-24-A2R is obsolete. The ENW-C9A02A3E is an active product with ongoing manufacturer support and availability.

Q: Are both modules compatible with Zigbee protocol implementations?

A: Both modules support 802.15.4 standard at 2.4GHz. The ATZB-24-A2R explicitly lists Zigbee protocol support. The ENW-C9A02A3E does not specify protocol in the provided data; protocol compatibility must be confirmed through Panasonic technical documentation.

Q: What are the key electrical differences between these modules?

A: The ENW-C9A02A3E exhibits higher current consumption (35.5mA receive, 41.5mA transmit versus 21.8mA and 20.8mA respectively), reduced receiver sensitivity by 4dB, and a higher minimum supply voltage (2.1V versus 1.8V).

Q: Are both modules RoHS compliant?

A: Yes, both the ATZB-24-A2R and ENW-C9A02A3E are ROHS3 compliant.

Q: What serial interfaces are available on each module?

A: The ATZB-24-A2R provides I2C, JTAG, SPI, UART, and USART. The ENW-C9A02A3E provides I2C, SPI, and UART. Applications requiring JTAG or USART must address this interface reduction.
