Substitute Part Grouping Explanation

Substitution of the AD8099ARD is determined by electrical and mechanical parameter equivalence within the voltage feedback amplifier category. The substitute part must satisfy the following criteria:

Electrical Parameter Matching:

• Amplifier type: Voltage feedback architecture
• Number of circuits: Single circuit configuration
• Slew rate: 1350 V/µs
• Bandwidth (-3dB): 510 MHz
• Input bias current: 6 µA
• Input offset voltage: 100 µV
• Supply current: 15 mA
• Output current per channel: 178 mA
• Supply voltage range: 5 V to 12 V
• Operating temperature range: -40°C to 125°C

Mechanical Parameter Matching:

• Package type: 8-SOIC with exposed pad
• Mounting technology: Surface mount
• Moisture sensitivity level: MSL 3 (168 hours)

The AD8099ARDZ qualifies as a direct substitute based on complete electrical and mechanical parameter equivalence. The primary distinction between the main part and substitute is product status and packaging format, not functional or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AD8099ARDZ is the direct substitute for the AD8099ARD. Both components are manufactured by Analog Devices Inc. and share identical electrical specifications and mechanical package characteristics. The AD8099ARDZ holds active product status, ensuring continued manufacturer support and availability, whereas the AD8099ARD is classified as obsolete.

Selection of the AD8099ARDZ is appropriate for new designs, production continuity, and system maintenance applications. The substitute part maintains full functional and performance equivalence with the original component across all specified electrical parameters, operating conditions, and package requirements.

The primary difference between the two parts is packaging format: the AD8099ARD is supplied in tape and reel format, while the AD8099ARDZ is supplied in tube format. This distinction affects handling, storage, and assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AD8099ARDZ be used as a direct replacement for the AD8099ARD in existing designs?

A: Yes. The AD8099ARDZ is electrically and mechanically equivalent to the AD8099ARD. All electrical parameters, operating temperature range, supply voltage specifications, and package dimensions are identical. The components are pin-compatible and functionally interchangeable.

Q: What is the difference between the AD8099ARD and AD8099ARDZ?

A: The primary differences are product status and packaging format. The AD8099ARD is obsolete and supplied in tape and reel format. The AD8099ARDZ is active and supplied in tube format. Electrical specifications and package type (8-SOIC with exposed pad) are identical.

Q: Why is the AD8099ARD classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this specific part number variant. The AD8099ARDZ remains in active production and serves as the current equivalent.

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

A: The AD8099ARDZ includes RoHS3 compliance and REACH unaffected status documentation. Both parts share the same ECCN (EAR99) and HTSUS (8542.33.0001) classifications and identical moisture sensitivity level (MSL 3, 168 hours).

Q: What is the moisture sensitivity level, and how does it affect handling?

A: Both parts have MSL 3 rating with a 168-hour floor life. This classification specifies moisture absorption limits and baking requirements for components exposed to humid environments. Proper storage in dry conditions and adherence to IPC-A-610 standards is required.

Q: Can the packaging format difference affect circuit board assembly?

A: Yes. Tape and reel format (AD8099ARD) is optimized for automated pick-and-place assembly, while tube format (AD8099ARDZ) is typically used for manual assembly or lower-volume production. Assembly equipment compatibility should be verified based on your manufacturing process.

Q: What is the base product number, and how does it relate to these part numbers?

A: The base product number is AD8099. Both the AD8099ARD and AD8099ARDZ are variants of this base product, differentiated by packaging format and product status. The base number identifies the core amplifier design and electrical specifications.

Q: Are the electrical specifications guaranteed across the full operating temperature range?

A: Yes. Both parts maintain specified electrical performance across the -40°C to 125°C operating temperature range. This includes slew rate (1350 V/µs), bandwidth (510 MHz), input bias current (6 µA), and all other listed parameters.
