Substitute Part Grouping Explanation

Substitution eligibility for the AT86RF233-ZUS is determined by strict equivalence across the following critical parameters:

• RF Family/Standard: 802.15.4, General ISM > 1GHz
• Protocol Support: 6LoWPAN, Zigbee®
• Frequency: 2.4GHz
• Modulation: O-QPSK
• Data Rate (Max): 2Mbps
• Power Output: 4dBm
• Sensitivity: -101dBm
• Memory Size: 128B SRAM
• Serial Interface: SPI
• Supply Voltage: 1.8V ~ 3.6V
• Package / Case: 32-VFQFN Exposed Pad
• Mounting Type: Surface Mount

The AT86RF233-ZF qualifies as a direct substitute based on identical electrical specifications and package configuration. Both parts share the same base product number (AT86RF233) and maintain full compatibility across all functional parameters.

Parameter Comparison

Engineering Selection Recommendations

The AT86RF233-ZF is the qualified substitute for the obsolete AT86RF233-ZUS. Both components maintain identical electrical and functional specifications across all critical RF and MCU parameters. The primary distinction is product status: AT86RF233-ZUS is obsolete while AT86RF233-ZF is active, ensuring continued availability and supply chain support.

The AT86RF233-ZF offers an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), providing additional thermal margin for demanding applications. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Packaging differences are limited to supplier delivery format: AT86RF233-ZUS ships in standard packaging while AT86RF233-ZF is supplied in trays. This distinction does not affect electrical compatibility or PCB assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can AT86RF233-ZF directly replace AT86RF233-ZUS in existing designs?

A: Yes. Both parts share identical electrical specifications, RF performance characteristics, and package geometry (32-VFQFN Exposed Pad). No circuit modifications or firmware changes are required for substitution.

Q: What is the significance of the packaging difference between -ZUS and -ZF?

A: The packaging designation indicates supplier delivery format only. -ZUS uses standard packaging while -ZF uses tray packaging. This affects logistics and handling but does not impact electrical performance or PCB assembly compatibility.

Q: Why does AT86RF233-ZF have a higher maximum operating temperature?

A: AT86RF233-ZF supports -40°C ~ 125°C while AT86RF233-ZUS supports -40°C ~ 85°C. This extended range provides additional thermal headroom for applications operating in elevated ambient conditions. Both parts are functionally equivalent at the overlapping temperature range (-40°C ~ 85°C).

Q: Are there any compliance or certification differences between these parts?

A: No. Both AT86RF233-ZUS and AT86RF233-ZF maintain identical RoHS3 compliance, REACH unaffected status, and MSL 3 moisture sensitivity ratings. Regulatory and environmental compliance is equivalent.

Q: What is the primary reason to transition from AT86RF233-ZUS to AT86RF233-ZF?

A: AT86RF233-ZUS is classified as obsolete, creating supply chain risk. AT86RF233-ZF is active and maintains full inventory availability, ensuring long-term component sourcing for new production and field replacements.
