MAX6339OUT-T Equivalent & Substitute Parts

Part Overview

The MAX6339OUT-T is a multi-voltage supervisor IC designed for power management applications, monitoring four voltage channels with open drain or open collector output configuration. This device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs. The supervisor provides active low reset functionality with a 140ms minimum timeout, operating across the industrial temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX6339OUT-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Multi-voltage supervisor with 4-channel monitoring capability
• Voltage Thresholds: Identical threshold configuration (2.93V, 4.38V, Adjustable, -4.38V)
• Output Configuration: Open drain or open collector output topology
• Reset Characteristics: Active low reset with 140ms minimum timeout
• Operating Temperature Range: -40°C to 85°C industrial range
• Package Specification: SOT-23-6 surface mount package
• Electrical Performance: Equivalent electrical specifications across all monitored channels

The MAX6339OUT+T qualifies as a direct substitute based on identical electrical specifications, functional parameters, and package configuration. The primary distinction lies in product status and compliance certifications rather than technical performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX6339OUT+T serves as the direct functional equivalent for the obsolete MAX6339OUT-T. Selection between these parts is determined by application requirements and regulatory compliance:

For New Designs and Ongoing Production: The MAX6339OUT+T is the appropriate selection. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. The tape and reel packaging format supports automated assembly processes typical of production environments.

For Legacy System Support: The MAX6339OUT-T remains available in limited inventory (805 units) for applications where RoHS non-compliance is acceptable or where existing certifications preclude substitution. However, the MAX6339OUT+T provides superior long-term availability and regulatory alignment.

Both parts share identical functional parameters, electrical performance, and physical package specifications, ensuring direct substitution without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can MAX6339OUT+T replace MAX6339OUT-T in existing designs?

A: Yes. Both parts are electrically and functionally identical across all monitored voltage channels, output configuration, reset characteristics, and operating temperature range. The SOT-23-6 package footprint is identical, enabling direct PCB substitution without layout modification.

Q: What is the primary difference between these two part numbers?

A: The MAX6339OUT+T is the active production variant with ROHS3 compliance and tape & reel packaging, while the MAX6339OUT-T is the obsolete variant supplied in tube packaging with RoHS non-compliance. Electrical specifications and functional performance are identical.

Q: Are there any compatibility concerns with the packaging format change?

A: No. The transition from tube to tape & reel packaging affects only the supply format and handling process. The component itself, package type (SOT-23-6), and all electrical specifications remain unchanged. Automated assembly equipment can process tape & reel format directly.

Q: Does the ROHS3 compliance of MAX6339OUT+T affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. The MAX6339OUT+T delivers identical functional specifications, voltage thresholds, reset timing, and output characteristics as the MAX6339OUT-T.

Q: What is the inventory status for these parts?

A: MAX6339OUT-T inventory is limited to 805 units in new original condition. MAX6339OUT+T has significantly higher availability at 3157 units in new original condition, providing superior supply chain reliability for production requirements.
