MAX6303ESA Equivalent & Substitute Parts

Part Overview

The MAX6303ESA is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated designed for power management applications. It functions as a simple reset/power-on reset controller with push-pull, totem pole output configuration, monitoring a single voltage channel with adjustable/selectable threshold settings. The part is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or ongoing production requirements. The MAX6303ESA+ serves as the direct substitute, offering identical electrical and mechanical specifications while maintaining active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The MAX6303ESA+ qualifies as a direct substitute based on strict parameter equivalence across all electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Identical supervisor function: Simple reset/power-on reset controller
• Single voltage channel monitoring with adjustable/selectable threshold
• Matching output configuration: Push-Pull, Totem Pole
• Active Low reset logic with 2.8ms minimum reset timeout
• Identical operating temperature range: -40°C ~ 85°C
• Identical package: 8-SOIC (0.154", 3.90mm Width)
• Matching MSL rating: 1 (Unlimited)

The MAX6303ESA+ maintains all functional and mechanical parameters of the original part while offering improved product status and compliance certifications, making it suitable for direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The MAX6303ESA+ is the appropriate selection for new designs and production continuity. While the MAX6303ESA remains functionally equivalent, its obsolete status and RoHS non-compliant certification present supply chain and regulatory constraints. The MAX6303ESA+ offers ROHS3 compliance, ensuring alignment with current environmental and regulatory requirements. Both parts maintain identical electrical performance and package specifications, enabling direct substitution without circuit redesign. Selection between these parts should be based on product lifecycle requirements and regulatory compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can MAX6303ESA+ directly replace MAX6303ESA in existing designs?

A: Yes. The MAX6303ESA+ maintains identical electrical specifications, output configuration, reset timing, operating temperature range, and 8-SOIC package dimensions. No circuit modifications are required for direct substitution.

Q: What is the primary difference between MAX6303ESA and MAX6303ESA+?

A: The MAX6303ESA+ is an active product with ROHS3 compliance, while the MAX6303ESA is obsolete and RoHS non-compliant. All functional and mechanical parameters remain identical.

Q: Are there any packaging differences between these parts?

A: No. Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging with matching MSL rating of 1 (Unlimited).

Q: What determines substitution eligibility for supervisor ICs in this category?

A: Substitution requires matching supervisor function type, voltage monitoring channels, threshold configuration, output topology, reset logic polarity, reset timeout specifications, operating temperature range, and package form factor.

Q: Is the MAX6303ESA+ suitable for new production designs?

A: Yes. The active product status and ROHS3 compliance make the MAX6303ESA+ the recommended choice for new designs and ongoing production requirements.
