Substitute Part Grouping Explanation

Substitution of the MAX406BESA-T is determined by strict equivalence across all electrical and mechanical parameters. The substitute part MAX406BESA+T maintains identical specifications across the following critical parameters:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Slew Rate: 0.005 V/µs
• Gain Bandwidth Product: 8 kHz
• Current - Input Bias: 0.1 pA
• Voltage - Input Offset: 750 µV
• Current - Supply: 1 µA
• Current - Output / Channel: 600 µA
• Voltage - Supply Span: 2.5V to 10V
• Operating Temperature Range: -40°C to 85°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary distinction between the main part and substitute is the packaging format and product status. The MAX406BESA+T is supplied in Tape & Reel (TR) format with Active product status, whereas the MAX406BESA-T is Obsolete. Both parts share the identical base product number MAX406 and are manufactured by Analog Devices Inc./Maxim Integrated.

Parameter Comparison

Engineering Selection Recommendations

The MAX406BESA+T is the direct functional equivalent of the MAX406BESA-T. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The MAX406BESA-T is classified as Obsolete, indicating discontinued manufacturing and limited availability. The MAX406BESA+T maintains Active product status with Analog Devices Inc./Maxim Integrated, ensuring ongoing availability and supply chain continuity.

Compliance and Certification: Both parts maintain identical compliance certifications including ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. Moisture Sensitivity Level 1 (Unlimited) is maintained across both parts, indicating no special handling requirements.

Electrical and Mechanical Equivalence: All electrical parameters, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and operating temperature range, are identical between the main part and substitute. The 8-SOIC surface mount package with 0.154" width (3.90mm) is maintained.

Packaging Format Difference: The primary distinction is packaging format. The MAX406BESA-T is supplied in standard tube packaging, while the MAX406BESA+T is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact electrical performance or functional compatibility.

For applications requiring the MAX406BESA-T, the MAX406BESA+T provides complete functional substitution with the advantage of Active product status and improved supply availability.

Frequently Asked Questions (FAQ)
