MAX5035DASA Equivalent & Substitute Parts

Part Overview

The MAX5035DASA 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 output current regulator with an adjustable output range from 1.25V to 13.2V, supporting input voltages from 7.5V to 76V. The MAX5035DASA is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and procurement planning. The MAX5035DASA+ serves as the direct active substitute, offering identical electrical and mechanical specifications with current manufacturing availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5035DASA is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is the maintenance of identical specifications across input voltage range (7.5V to 76V), output voltage adjustability (1.25V to 13.2V), output current capacity (1A), switching frequency (125kHz), package type (8-SOIC), and operating temperature range (-40°C to 125°C). The MAX5035DASA+ qualifies as a direct substitute based on complete parameter alignment. The key differentiator between the main part and substitute is product status: the MAX5035DASA is obsolete, while the MAX5035DASA+ maintains active production status. Both parts share identical base product number (MAX5035), electrical ratings, and physical packaging specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX5035DASA+ is the appropriate substitute for the obsolete MAX5035DASA. Both parts maintain identical electrical specifications and physical packaging, ensuring direct compatibility in existing circuit designs. The MAX5035DASA+ carries active product status from Analog Devices Inc./Maxim Integrated, providing assured long-term availability and supply chain continuity. Both parts comply with ROHS3 standards and carry REACH unaffected status, meeting current environmental and regulatory requirements. The packaging difference (tube for MAX5035DASA+) does not affect electrical or mechanical compatibility and represents a standard industry variation in distribution format.

Frequently Asked Questions (FAQ)

Q: Can MAX5035DASA+ directly replace MAX5035DASA in existing designs? A: Yes. The MAX5035DASA+ provides complete electrical and mechanical equivalence to the MAX5035DASA. All voltage ratings, current specifications, switching frequency, operating temperature range, and 8-SOIC package dimensions are identical. No circuit modifications are required.

Q: What is the primary reason for substitution? A: The MAX5035DASA is classified as obsolete. The MAX5035DASA+ is the active equivalent from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are there any compliance or certification differences? A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1). Regulatory and environmental certifications are equivalent.

Q: Does the packaging format (tube vs. unspecified) affect compatibility? A: No. Packaging format refers to the distribution method and does not affect electrical performance or physical component dimensions. The 8-SOIC package specifications remain identical.

Q: What are the critical parameters for substitution validation? A: Input voltage range (7.5V to 76V), output voltage adjustability (1.25V to 13.2V), output current (1A), switching frequency (125kHz), operating temperature range (-40°C to 125°C), and 8-SOIC package type must all remain constant for valid substitution.
