Substitute Part Grouping Explanation

Substitution of the MAX409BESA-T is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the MAX409BESA+T, which shares identical electrical specifications with the main part number. The substitution logic is based on the following criteria:

Electrical Parameter Equivalence:

• Identical slew rate (0.08 V/µs)
• Identical gain bandwidth product (150 kHz)
• Identical input bias current (0.1 pA)
• Identical input offset voltage (750 µV)
• Identical supply current (1 µA)
• Identical output current per channel (600 µA)
• Identical supply voltage range (2.5 V to 10 V)
• Identical operating temperature range (-40°C to 85°C)

Mechanical Parameter Equivalence:

• Identical package type (8-SOIC)
• Identical package dimensions (0.154", 3.90mm Width)
• Identical mounting type (Surface Mount)

Compliance Equivalence:

• Both parts are ROHS3 Compliant
• Both parts are REACH Unaffected
• Both parts share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications

The distinction between MAX409BESA-T and MAX409BESA+T lies in packaging format: the main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. Additionally, the substitute part maintains Active product status, ensuring ongoing manufacturer support and availability.
