Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5033BASA-T is determined by strict equivalence across the following critical parameters:

• Topology & Function: Buck (step-down) switching regulator topology
• Output Specification: Fixed 5V output voltage
• Current Rating: 500mA output current capacity
• Input Voltage Range: 7.5V to 76V minimum and maximum ratings
• Switching Frequency: 125kHz operation
• Package Compatibility: 8-SOIC (0.154", 3.90mm Width) surface mount package
• Thermal Range: -40°C to 125°C junction temperature rating
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The MAX5033BASA+T qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAX5033BASA+T is the direct functional equivalent for the obsolete MAX5033BASA-T. Both parts share identical electrical characteristics, thermal specifications, and package geometry. The MAX5033BASA+T maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring continued availability and technical support.

Selection of the MAX5033BASA+T is appropriate for replacement applications, redesigns, and new implementations requiring 5V buck regulation at 500mA from input sources spanning 7.5V to 76V. Both parts satisfy ROHS3 compliance requirements and operate across the full industrial temperature range of -40°C to 125°C.

The packaging format difference (Cut Tape and Digi-Reel for the substitute) does not affect electrical or mechanical compatibility and reflects standard distribution practices for active components.

Frequently Asked Questions (FAQ)

Q: Can the MAX5033BASA+T directly replace the MAX5033BASA-T in existing designs?

A: Yes. The MAX5033BASA+T is electrically and mechanically identical to the MAX5033BASA-T. Both parts feature the same 8-SOIC package footprint, output specifications, input voltage range, and thermal characteristics. No circuit modifications are required.

Q: What is the significance of the product status difference between these parts?

A: The MAX5033BASA-T is classified as obsolete, indicating it is no longer manufactured or supported by Analog Devices Inc./Maxim Integrated. The MAX5033BASA+T maintains active status, ensuring ongoing availability, technical documentation, and manufacturing support.

Q: Are there package compatibility concerns between these parts?

A: No. Both the MAX5033BASA-T and MAX5033BASA+T use the 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints and assembly processes are identical.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Compliance certifications are equivalent.

Q: What is the difference between the "-T" and "+T" designations?

A: The "-T" and "+T" suffixes indicate different packaging and distribution formats. The MAX5033BASA-T uses standard tape packaging, while the MAX5033BASA+T is supplied in Cut Tape and Digi-Reel formats. Electrical and functional specifications remain identical.
