Substitute Part Grouping Explanation

Substitution of the MAX406BESA is determined by strict equivalence across all electrical and mechanical parameters. The substitute relationship is based on the following criteria:

Electrical Parameter Equivalence:

• Amplifier type (General Purpose)
• Number of circuits (1)
• Output type (Rail-to-Rail)
• Slew rate (0.005 V/µs)
• Gain bandwidth product (8 kHz)
• Input bias current (0.1 pA)
• Input offset voltage (750 µV)
• Supply current (1 µA)
• Output current per channel (600 µA)
• Supply voltage range (2.5V to 10V)
• Operating temperature range (-40°C to 85°C)

Mechanical Parameter Equivalence:

• Package type (8-SOIC)
• Package dimensions (0.154", 3.90mm Width)
• Mounting type (Surface Mount)

Compliance Equivalence:

• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

The MAX406BESA+ is identified as a direct substitute based on identical electrical specifications and mechanical packaging, with the distinction that it is available in Tube packaging and maintains Active product status.

Parameter Comparison

Engineering Selection Recommendations

The MAX406BESA+ is the direct substitute for the MAX406BESA. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The primary distinction is product status: the MAX406BESA is classified as obsolete, while the MAX406BESA+ maintains active production status.

For new designs and ongoing production requiring the MAX406BESA, the MAX406BESA+ is the appropriate selection. Both components meet ROHS3 compliance requirements and carry identical moisture sensitivity ratings. The MAX406BESA+ is available in higher inventory quantities (2693 pieces) compared to the MAX406BESA (939 pieces), supporting supply chain continuity.

Packaging format differs between the two variants: MAX406BESA is supplied in standard packaging, while MAX406BESA+ is supplied in Tube packaging. This distinction does not affect electrical performance or mechanical compatibility in surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can MAX406BESA+ be used as a direct replacement for MAX406BESA in existing designs?
