Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8591ARTZ-REEL is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters:

• Amplifier type (General Purpose)
• Number of circuits (1)
• Output configuration (Rail-to-Rail)
• Slew rate (5 V/µs)
• Gain bandwidth product (3 MHz)
• Input bias current (5 pA)
• Input offset voltage (2 mV)
• Supply current (1.25 mA)
• Output current per channel (250 mA)
• Supply voltage range (2.5 V to 6 V)
• Operating temperature range (-40°C to 85°C)

Mechanical Parameters:

• Mounting type (Surface Mount)
• Package type (SOT-23-6)
• Moisture sensitivity level (MSL 1)

Substitute parts must match all electrical specifications and mechanical requirements without deviation. Product status and compliance certifications are secondary factors that influence selection priority but do not alter electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AD8591ARTZ-REEL7 is a direct electrical and mechanical equivalent to the AD8591ARTZ-REEL. All specified electrical parameters, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range, are identical. The package type (SOT-23-6) and mounting configuration (Surface Mount) are unchanged.

Primary Selection Advantage:

The AD8591ARTZ-REEL7 carries an active product status, whereas the main part is obsolete. This status difference ensures long-term availability and supply chain continuity. The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in most jurisdictions.

Packaging Consideration:

The AD8591ARTZ-REEL7 is supplied in Cut Tape (CT) and Digi-Reel® packaging, which differs from the original part's packaging designation. This packaging difference does not affect electrical performance or mechanical compatibility but may influence procurement logistics and handling procedures.

Direct Substitution:

The AD8591ARTZ-REEL7 functions as a direct pin-for-pin and electrical substitute in all applications where the AD8591ARTZ-REEL was originally specified. No circuit modifications, layout adjustments, or design changes are required.

Frequently Asked Questions (FAQ)

Q: Can the AD8591ARTZ-REEL7 be used as a direct replacement for the AD8591ARTZ-REEL?

A: Yes. The AD8591ARTZ-REEL7 is electrically and mechanically equivalent. All electrical parameters, including amplifier type, output configuration, slew rate, gain bandwidth product, bias current, offset voltage, supply current, output current, supply voltage range, and operating temperature range are identical. The SOT-23-6 package and surface-mount configuration are unchanged.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance certifications. The AD8591ARTZ-REEL is obsolete, while the AD8591ARTZ-REEL7 is active. The substitute part is ROHS3 compliant and REACH unaffected. Packaging format differs (Cut Tape and Digi-Reel® versus the original designation), but this does not affect electrical performance or PCB compatibility.

Q: Are there any circuit design changes required when switching from AD8591ARTZ-REEL to AD8591ARTZ-REEL7?

A: No circuit design changes are required. The substitute part maintains identical electrical specifications and pin configuration. Existing schematics, PCB layouts, and application circuits require no modification.

Q: Does the packaging format change affect PCB assembly?

A: The packaging format (Cut Tape and Digi-Reel®) is a supply and handling consideration, not a PCB assembly consideration. Both formats deliver the same SOT-23-6 component for surface-mount assembly. Assembly equipment and processes remain unchanged.

Q: Is the AD8591ARTZ-REEL7 suitable for new designs?

A: Yes. The active product status and regulatory compliance (ROHS3, REACH unaffected) make the AD8591ARTZ-REEL7 suitable for new designs. The identical electrical specifications ensure compatibility with existing application requirements.

Q: What is the inventory status of the substitute part?

A: The AD8591ARTZ-REEL7 has 26,205 pieces in stock as new original inventory, providing reliable supply availability compared to the obsolete main part.
