Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD626AR is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters:

• Amplifier type (Differential)
• Number of circuits (1)
• Slew rate (0.22 V/µs)
• -3dB bandwidth (100 kHz)
• Voltage input offset (50 µV)
• Supply current (1.5 mA)
• Output current per channel (12 mA)
• Supply voltage range (2.4V to 12V minimum and maximum)
• Operating temperature range (-40°C to 85°C)

Mechanical Parameters:

• Mounting type (Surface Mount)
• Package type (8-SOIC with 0.154" / 3.90mm width)
• Moisture sensitivity level (1 - Unlimited)

The AD626ARZ qualifies as a direct substitute based on complete electrical and mechanical parameter alignment with the AD626AR across all specified criteria.

Parameter Comparison

Engineering Selection Recommendations

The AD626ARZ is the direct equivalent substitute for the AD626AR. Both parts share identical electrical specifications and mechanical packaging, ensuring functional interchangeability in circuit applications.

The AD626ARZ carries an active product status, contrasting with the obsolete status of the AD626AR. This distinction is significant for long-term supply chain planning and component availability.

The AD626ARZ is certified as ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory compliance standards. These certifications support integration into modern manufacturing and distribution environments where such compliance is required.

Both parts are manufactured by Analog Devices Inc. under the base product number AD626, with the ARZ variant supplied in tube packaging format. The electrical performance, thermal operating range, and physical package dimensions are identical, supporting direct substitution without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the AD626ARZ be used as a direct replacement for the AD626AR in existing designs?

A: Yes. The AD626ARZ is electrically and mechanically equivalent to the AD626AR. All electrical parameters, including slew rate, bandwidth, input offset voltage, supply current, output current, and supply voltage range are identical. The physical package dimensions and mounting type are also identical, enabling direct substitution without circuit modification.

Q: What is the difference between the AD626AR and AD626ARZ?

A: The primary differences are product status and packaging format. The AD626AR is obsolete, while the AD626ARZ is active. The AD626ARZ is supplied in tube packaging, whereas the AD626AR packaging format is not specified. The AD626ARZ includes ROHS3 compliance and REACH unaffected certifications. All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the AD626ARZ for the AD626AR?

A: No compatibility concerns exist. Both parts are housed in the 8-SOIC package with identical dimensions (0.154" / 3.90mm width). The surface mount mounting type, moisture sensitivity level, and all electrical parameters are identical. Printed circuit board layouts and assembly processes require no modification.

Q: Why is the AD626AR listed as obsolete?

A: The AD626AR carries an obsolete product status designation. The AD626ARZ, sharing the same base product number AD626, represents the active equivalent in the product line. For new designs and ongoing production, the AD626ARZ is the recommended source.

Q: What certifications does the AD626ARZ carry?

A: The AD626ARZ is ROHS3 compliant and REACH unaffected. These certifications indicate compliance with current environmental and chemical substance regulations applicable to electronic components in regulated markets.

Q: Is the 8-SOIC package suitable for automated assembly?

A: Yes. The 8-SOIC package is a standard surface mount package format compatible with automated pick-and-place assembly equipment and reflow soldering processes. The 0.154" (3.90mm) width is within standard handling and placement tolerances for modern manufacturing equipment.

Q: What is the moisture sensitivity level, and what does it mean?

A: Both the AD626AR and AD626ARZ carry a moisture sensitivity level (MSL) of 1, designated as unlimited. This classification indicates the component has no moisture sensitivity restrictions and requires no special moisture control measures during storage, handling, or assembly.
