Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8302ARU is determined by strict equivalence across the following critical parameters:

• Frequency specification: 2.7GHz
• RF detection type: General Purpose
• Input dynamic range: -60dBm to 0dBm
• Detection accuracy: ±0.5dB
• Supply voltage range: 2.7V to 5.5V
• Supply current: 23 mA
• Package configuration: 14-TSSOP with identical physical dimensions
• Moisture sensitivity classification: MSL 1

The AD8302ARUZ meets all substitution criteria as a direct equivalent. Both parts share identical base product number (AD8302), electrical specifications, and mechanical packaging. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The AD8302ARUZ is the direct functional equivalent for the obsolete AD8302ARU. Selection of the AD8302ARUZ is supported by:

• Identical electrical performance across all RF detection parameters
• Identical mechanical packaging and PCB footprint compatibility
• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status providing regulatory alignment for current manufacturing standards
• Equivalent moisture sensitivity classification maintaining assembly process compatibility

For applications currently using AD8302ARU, transition to AD8302ARUZ requires no circuit redesign or PCB layout modification. The substitute part is pin-compatible and functionally interchangeable.

Frequently Asked Questions (FAQ)

Q: Can AD8302ARUZ be used as a direct replacement for AD8302ARU in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No circuit modifications or PCB redesign is required. Pin configuration, package dimensions, and electrical performance are equivalent.

Q: What is the primary reason to transition from AD8302ARU to AD8302ARUZ?

A: The AD8302ARU is classified as obsolete, creating long-term supply and support risks. The AD8302ARUZ maintains identical specifications while offering active product status and current manufacturing support from Analog Devices Inc.

Q: Are there any compliance differences between these parts?

A: The AD8302ARUZ provides explicit ROHS3 compliance and REACH unaffected status. These certifications align with current regulatory requirements for electronic component manufacturing and are advantageous for new production designs.

Q: Does the packaging format difference (standard vs. tube) affect electrical performance?

A: No. Packaging format affects only logistics and handling. The tube packaging of AD8302ARUZ provides improved component protection during storage and transport but does not alter electrical specifications or performance characteristics.

Q: Are both parts suitable for 2.7GHz RF detection applications?

A: Yes. Both AD8302ARU and AD8302ARUZ are specified for 2.7GHz general-purpose RF detection with -60dBm to 0dBm input range and ±0.5dB accuracy. Frequency performance and detection characteristics are identical.

Q: What is the MSL rating and why is it relevant?

A: Both parts carry MSL 1 (Unlimited) rating, indicating minimal moisture sensitivity. This classification allows extended shelf life and simplified storage requirements without special humidity control measures.
