MAX5035DUSA-T Equivalent & Substitute Parts

Part Overview

The MAX5035DUSA-T is a buck switching regulator IC from Analog Devices Inc./Maxim Integrated, designed for step-down voltage conversion with positive adjustable output. This device operates as a 1A power management solution with an input voltage range of 7.5V to 76V and adjustable output from 1.25V to 13.2V. The part is classified as obsolete, which necessitates identification of equivalent alternatives for ongoing design support and procurement requirements. Active substitute parts maintain identical electrical and mechanical specifications while offering improved availability and current product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5035DUSA-T is based on strict equivalence of electrical and mechanical parameters. The primary substitute, MAX5035DUSA+T, maintains identical specifications across all critical functional parameters: input voltage range (7.5V to 76V), adjustable output voltage (1.25V to 13.2V), output current (1A), switching frequency (125kHz), package type (8-SOIC), and operating temperature range (0°C to 85°C). Both parts share the same base product number (MAX5035) and are manufactured by the same supplier. The key differentiator is product status: the original part is obsolete while the substitute is active, with significantly higher inventory availability. Packaging format differs (standard vs. Cut Tape/Digi-Reel), but this does not affect electrical or mechanical compatibility. Compliance certifications (RoHS3, REACH, MSL Level 1) are identical across both parts.

Parameter Comparison

Engineering Selection Recommendations

The MAX5035DUSA+T is a direct functional equivalent to the MAX5035DUSA-T. Selection of the substitute part is supported by identical electrical specifications, mechanical compatibility, and regulatory compliance status. The obsolete status of the original part combined with the active status and superior inventory availability of the substitute part establishes MAX5035DUSA+T as the appropriate choice for new designs and ongoing procurement. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The identical 8-SOIC package footprint and pin configuration enable direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Are MAX5035DUSA-T and MAX5035DUSA+T electrically identical? A: Yes. Both parts share identical electrical specifications including input voltage range (7.5V to 76V), adjustable output voltage (1.25V to 13.2V), output current (1A), and switching frequency (125kHz).

Q: Can MAX5035DUSA+T be used as a direct replacement on existing PCBs designed for MAX5035DUSA-T? A: Yes. Both parts use the 8-SOIC package with identical pin configuration and mechanical dimensions (0.154", 3.90mm width), enabling direct board-level substitution.

Q: What is the difference between the two part numbers? A: The primary difference is product status and packaging format. MAX5035DUSA-T is obsolete with limited inventory, while MAX5035DUSA+T is active with higher availability in Cut Tape and Digi-Reel packaging formats.

Q: Do both parts meet the same compliance requirements? A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Is there any performance difference between these parts? A: No. Operating temperature range (0°C to 85°C), switching frequency (125kHz), and all functional parameters are identical.
