MAX5035BASA-T Equivalent & Substitute Parts

Part Overview

The MAX5035BASA-T is a buck switching regulator IC from Analog Devices Inc./Maxim Integrated, designed for step-down voltage conversion with a fixed 5V output at 1A 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. The MAX5035BASA-T is currently classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5035BASA-T is determined by strict equivalence across the following critical parameters:

• Topology & Function: Buck (step-down) converter with positive fixed output
• Output Specifications: 5V fixed output at 1A maximum current
• Input Voltage Range: 7.5V to 76V minimum and maximum input voltages
• Switching Frequency: 125kHz operating frequency
• Package Compatibility: 8-SOIC (0.154", 3.90mm Width) surface mount package
• Electrical Characteristics: Non-synchronous rectifier topology, operating temperature range of -40°C to 125°C
• Compliance: ROHS3 compliant, MSL Level 1

The MAX5035BASA+T meets all substitution criteria as a direct equivalent part, differing only in packaging format (Cut Tape & Digi-Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MAX5035BASA+T is a direct functional equivalent to the MAX5035BASA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, package geometry, and compliance certifications (ROHS3 compliant, MSL Level 1). The primary distinction is product status: the MAX5035BASA-T is obsolete while the MAX5035BASA+T maintains active status with current manufacturing availability. For new designs or production continuity, the MAX5035BASA+T is the appropriate selection. The only operational difference is packaging format: the substitute is supplied in Cut Tape and Digi-Reel formats, which do not affect electrical performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX5035BASA+T be used as a direct replacement for MAX5035BASA-T?

A: Yes. Both parts are electrically and mechanically identical. They share the same die, package footprint (8-SOIC), and all electrical specifications including input voltage range (7.5V–76V), fixed 5V output, 1A output current, and 125kHz switching frequency.

Q: What is the difference between MAX5035BASA-T and MAX5035BASA+T?

A: The parts are functionally equivalent. The difference is in packaging format and product lifecycle status. MAX5035BASA-T is obsolete; MAX5035BASA+T is active and supplied in Cut Tape and Digi-Reel packaging.

Q: Are there any PCB layout or design changes required when switching to MAX5035BASA+T?

A: No. Both parts use the identical 8-SOIC (0.154", 3.90mm Width) package with the same pinout and footprint. No PCB modifications are necessary.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MAX5035BASA-T and MAX5035BASA+T are ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity level), REACH unaffected status, and identical ECCN and HTSUS classifications.

Q: What is the operating temperature range for these parts?

A: Both parts operate across -40°C to 125°C junction temperature (TJ), suitable for industrial and extended temperature applications.
