MAX5033BASA Equivalent & Substitute Parts

Part Overview

The MAX5033BASA is a buck switching regulator IC from Analog Devices Inc./Maxim Integrated, designed for step-down voltage conversion with a fixed 5V output at 500mA output current. This device operates across a wide input voltage range of 7.5V to 76V and is housed in an 8-SOIC surface mount package with a switching frequency of 125kHz.

The MAX5033BASA is classified as obsolete, which necessitates identification of equivalent substitute parts for new designs or production continuity. Active alternatives with identical electrical and mechanical specifications are available to ensure design compatibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5033BASA is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for direct substitution:

• Output voltage: 5V fixed
• Output current capability: 500mA
• Input voltage range: 7.5V to 76V
• Switching frequency: 125kHz
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Operating temperature range: -40°C to 125°C
• Synchronous rectifier configuration: Non-synchronous
• Topology: Buck (step-down)

The MAX5033BASA+ meets all these criteria and qualifies as a direct equivalent substitute. The primary distinction between these parts is product status and packaging format, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX5033BASA+ is the direct equivalent substitute for the MAX5033BASA. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package dimensions. The MAX5033BASA+ carries Active product status, ensuring continued availability and support, whereas the MAX5033BASA is classified as Obsolete.
