Substitute Part Grouping Explanation

Substitution of the MAX5033DASA-T is determined by strict equivalence across the following critical parameters:

  • Topology & Function: Buck switching regulator with step-down capability
  • Output Configuration: Positive adjustable output
  • Electrical Specifications: Input voltage range 7.5V–76V, output voltage range 1.221V–13.2V, 500mA output current
  • Switching Frequency: 125kHz operation
  • Package Compatibility: 8-SOIC (0.154", 3.90mm Width) surface mount package
  • Regulatory Compliance: ROHS3 compliant, MSL Level 1

The substitute part must match all electrical parameters and physical package specifications to ensure direct functional replacement without circuit redesign.

Engineering Selection Recommendations

The MAX5033DASA+T is the direct substitute for the MAX5033DASA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: the MAX5033DASA-T is obsolete, while the MAX5033DASA+T maintains active status with significantly higher inventory availability (15,631 units versus 859 units). Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring equivalent regulatory and environmental performance.

The packaging difference (Cut Tape & Digi-Reel for the substitute versus unspecified for the main part) does not affect functional compatibility and reflects standard distribution formats for active components.

Frequently Asked Questions (FAQ)

Q: Can the MAX5033DASA+T directly replace the MAX5033DASA-T in existing designs?

A: Yes. The MAX5033DASA+T is electrically and mechanically identical to the MAX5033DASA-T across all specified parameters. No circuit modifications are required for substitution.

Q: What is the difference between MAX5033DASA-T and MAX5033DASA+T?

A: The parts are functionally equivalent. The primary differences are product status (obsolete versus active) and packaging format (unspecified versus Cut Tape & Digi-Reel). The "+T" designation indicates the active production variant with standard tape packaging.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance status and MSL Level 1 rating. Regulatory certifications (REACH Unaffected, ECCN EAR99) are equivalent.

Q: What are the critical parameters for substitution compatibility?

A: Substitution requires matching input voltage range (7.5V–76V), output voltage range (1.221V–13.2V), output current (500mA), switching frequency (125kHz), package type (8-SOIC), and operating temperature range (-40°C to 125°C).

Q: Is the 8-SOIC package footprint identical between both parts?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pin configuration and PCB footprint requirements.
