MAX6339IUT-T Equivalent & Substitute Parts
Part Overview
The MAX6339IUT-T is a multi-voltage supervisor IC designed for power management applications, monitoring four independent voltage channels with open drain or open collector output configuration. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The supervisor provides active-low reset functionality with a 140ms minimum timeout, suitable for embedded systems requiring multi-rail voltage monitoring.

Frequently Asked Questions (FAQ)
Q: Can the MAX6339IUT+T be used as a direct replacement for MAX6339IUT-T in existing designs?
A: Yes. Both components share identical electrical specifications, voltage thresholds, reset timing, and SOT-23-6 package configuration. No circuit modifications are required for substitution.
Q: What is the difference between the two part numbers?
A: The primary differences are product status and packaging format. The MAX6339IUT-T is obsolete and supplied in bulk packaging, while the MAX6339IUT+T is an active product supplied in Tape & Reel format. The MAX6339IUT+T also carries ROHS3 compliance certification.
Q: Are the voltage monitoring thresholds identical?
A: Yes. Both parts monitor the same four voltage thresholds: 1.58V, 2.19V, 2.93V, and 4.38V. Reset behavior and timeout specifications are also identical.
Q: Does the packaging format affect electrical performance?
A: No. Tape & Reel packaging is a supply format only and does not affect component electrical characteristics or performance. The SOT-23-6 package remains unchanged.
Q: Is RoHS compliance a functional requirement for substitution?
A: RoHS compliance is a regulatory and procurement requirement. The MAX6339IUT+T meets ROHS3 standards, making it suitable for applications with environmental compliance mandates. The MAX6339IUT-T does not meet these standards.
Q: What is the operating temperature range for both parts?
A: Both the MAX6339IUT-T and MAX6339IUT+T operate across -40°C to 85°C, providing identical thermal performance specifications.
