Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8307AR is determined by strict equivalence across the following parameters:

• Manufacturer Identity: Both main and substitute parts originate from Analog Devices Inc.
• Base Product Number: Both parts share the AD8307 base designation, confirming functional equivalence.
• Device Type: Both are classified as logarithmic amplifiers with identical RSSI application focus.
• Package Specification: Both utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical and electrical compatibility.
• Mounting Type: Both are surface mount devices, compatible with identical PCB assembly processes.
• Moisture Sensitivity Level: Both maintain MSL 1 (Unlimited) rating, indicating equivalent environmental handling requirements.

The AD8307ARZ qualifies as a direct substitute based on these parameters. The primary distinction between the main part and substitute relates to product status and packaging format (tube versus unspecified for the main part), not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AD8307ARZ is the appropriate substitute for the AD8307AR based on the following engineering criteria:

Functional Equivalence: Both parts share identical base product designation (AD8307), device type (logarithmic amplifier), and application focus (RSSI). Electrical and functional characteristics are equivalent.

Package Compatibility: Both devices utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB layout, footprint, and assembly processes remain unchanged between the main part and substitute.

Product Status Consideration: The AD8307AR is classified as obsolete, while the AD8307ARZ maintains active product status. Selection of the AD8307ARZ ensures continued availability and manufacturer support for new designs and ongoing production requirements.

Compliance Status: The AD8307ARZ provides documented RoHS3 compliance and REACH unaffected status, offering enhanced regulatory alignment for applications subject to environmental and hazardous substance restrictions. The main part does not specify these compliance certifications.

Moisture Handling: Both parts maintain identical MSL 1 (Unlimited) ratings, confirming equivalent moisture sensitivity and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the AD8307ARZ directly replace the AD8307AR in existing designs?

A: Yes. Both parts share identical base product designation, device type, package specification (8-SOIC), and mounting type (surface mount). No design modifications are required for substitution.

Q: What is the primary difference between the AD8307AR and AD8307ARZ?

A: The primary differences are product status (obsolete versus active) and packaging format (tube for the substitute). Electrical characteristics, functional performance, and package dimensions are equivalent.

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

A: The AD8307ARZ provides documented RoHS3 compliance and REACH unaffected status. The AD8307AR does not specify these certifications. For applications requiring environmental compliance documentation, the AD8307ARZ is the appropriate selection.

Q: Do both parts require identical PCB footprints?

A: Yes. Both the AD8307AR and AD8307ARZ utilize the 8-SOIC (0.154", 3.90mm Width) package. PCB footprints, land patterns, and assembly processes are identical.

Q: What is the moisture sensitivity level for both parts?

A: Both parts maintain MSL 1 (Unlimited) rating, indicating unlimited shelf life under standard storage conditions without moisture bake requirements.

Q: Is the AD8307ARZ available in higher quantities than the AD8307AR?

A: Yes. The AD8307ARZ shows significantly higher inventory availability (15,423 pieces) compared to the AD8307AR (1,831 pieces), reflecting its active product status.

Q: Can I use the AD8307ARZ in new production designs?

A: Yes. The AD8307ARZ is classified as an active product with documented compliance certifications, making it suitable for new design implementations and ongoing production.
