Substitute Part Grouping Explanation

Substitution of the AD8626ARMZ-R2 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is the base product number AD8626, which defines the core amplifier architecture and performance specifications. All substitute parts must maintain identical values for:

Amplifier type (J-FET)
Number of circuits (2)
Output configuration (Rail-to-Rail)
Gain bandwidth product (5 MHz)
Slew rate (5 V/µs)
Input bias current (0.25 pA)
Input offset voltage (350 µV)
Supply current per channel (710 µA)
Output current per channel (15 mA)
Supply voltage range (5V to 26V)
Operating temperature range (-40°C to 85°C)
Package type (8-MSOP)
Mounting type (Surface Mount)

The AD8626ARMZ-REEL variant qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format and product status.

Engineering Selection Recommendations

The AD8626ARMZ-REEL is the direct substitute for the AD8626ARMZ-R2. Both components are manufactured by Analog Devices Inc. and share identical electrical and mechanical specifications across all critical parameters. The substitution is based on complete parameter equivalence.

The AD8626ARMZ-REEL offers the following advantages:

Active product status, ensuring continued availability and manufacturing support
ROHS3 compliance certification
REACH unaffected status
Digi-Reel® packaging format supporting automated assembly processes
Higher inventory availability (30,400 units in stock versus 953 units)

For new designs or system updates, the AD8626ARMZ-REEL is the appropriate selection. For existing systems currently using the AD8626ARMZ-R2, direct substitution is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the AD8626ARMZ-REEL be used as a direct replacement for the AD8626ARMZ-R2 in existing designs?

A: Yes. All electrical parameters, operating characteristics, and mechanical specifications are identical. No circuit modifications are required for substitution.

Q: What is the difference between the AD8626ARMZ-R2 and AD8626ARMZ-REEL?

A: The primary differences are product status and packaging format. The AD8626ARMZ-R2 is obsolete with standard packaging, while the AD8626ARMZ-REEL is active with Cut Tape and Digi-Reel® packaging options. Both components are electrically equivalent.

Q: Are there any compliance differences between these parts?

A: The AD8626ARMZ-REEL carries ROHS3 compliance and REACH unaffected certifications. Compliance information for the AD8626ARMZ-R2 is not specified in the available data. Both parts carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Q: What is the 8-MSOP package specification?

A: The 8-MSOP (8-pin Micro Small Outline Package) is a surface mount package with a width of 0.118 inches (3.00mm). This package type is identical for both the main part and substitute.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both the AD8626ARMZ-R2 and AD8626ARMZ-REEL have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Can the AD8626ARMZ-REEL be used in high-temperature applications?
