MAX967ESA-T Equivalent & Substitute Parts

Part Overview

The MAX967ESA-T is a dual-channel comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This device features open-drain, rail-to-rail output configuration in an 8-SOIC surface mount package. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across supply voltage, input offset, bias current, propagation delay, and hysteresis specifications while accommodating packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX967ESA-T is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Package type: 8-SOIC surface mount configuration
• Output type: Open-drain, rail-to-rail topology
• Supply voltage range: 1.6V ~ 5.5V compatibility
• Input offset voltage: Maximum 7mV @ 5.5V
• Input bias current: Maximum 0.05µA @ 5.5V
• Propagation delay: Maximum 20µs
• Hysteresis: ±1mV specification
• Operating temperature: -40°C ~ 85°C range
• Compliance certifications: ROHS3, MSL 1

Direct Substitute (Functionally Identical): MAX967ESA+T maintains all electrical and mechanical parameters of the main part with identical element count (2 comparators). This part differs only in packaging format (Tape & Reel) and product status (Active vs. Obsolete).

Parametric Equivalent (Functional Compatibility with Design Consideration): MAX965ESA+T provides equivalent electrical performance across all critical parameters but contains a single comparator element instead of two. This part is suitable for applications requiring only one comparator channel or where dual-channel redundancy is not required. All other specifications—supply voltage, input offset, bias current, propagation delay, hysteresis, and compliance—remain identical.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (MAX967ESA+T): The MAX967ESA+T is the primary substitute for obsolete MAX967ESA-T applications. Both parts maintain identical electrical specifications and dual-comparator architecture. The only distinction is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Bulk). This part is recommended for production designs requiring immediate obsolescence mitigation with zero functional modification.

For Single-Channel Applications (MAX965ESA+T): The MAX965ESA+T is suitable for designs utilizing only one comparator channel or where dual-channel functionality is not required. This part delivers identical performance across all critical electrical parameters: supply voltage, input offset, bias current, propagation delay, and hysteresis. The single-element configuration results in lower quiescent current (12µA vs. 16µA), providing a secondary benefit for power-constrained applications. Designs must accommodate the reduced element count in PCB layout and firmware logic.

Compliance and Availability: Both substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. Active product status for both alternatives ensures long-term availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can MAX967ESA+T directly replace MAX967ESA-T without PCB modification? A: Yes. Both parts are electrically and mechanically identical, differing only in packaging format (Tape & Reel vs. Bulk) and product status. No PCB layout changes are required. The 8-SOIC footprint and pin configuration remain unchanged.

Q: What is the key difference between MAX967ESA+T and MAX965ESA+T? A: The MAX967ESA+T contains two comparator elements, while MAX965ESA+T contains one. All other electrical specifications—supply voltage, input offset, bias current, propagation delay, and hysteresis—are identical. Selection depends on whether your application requires single or dual comparator functionality.

Q: Is MAX965ESA+T suitable for applications originally designed for MAX967ESA-T? A: MAX965ESA+T is suitable only if your design uses a single comparator channel. If the original design requires both comparator channels, MAX967ESA+T is the appropriate substitute. If only one channel is used in the original design, MAX965ESA+T provides equivalent performance with lower quiescent current consumption.

Q: Are there any temperature or voltage range limitations when substituting? A: No. Both substitute parts maintain the full operating temperature range (-40°C ~ 85°C) and supply voltage range (1.6V ~ 5.5V) of the original part. All critical electrical parameters remain within specification.

Q: What is the impact of the lower quiescent current in MAX965ESA+T? A: The MAX965ESA+T draws 12µA maximum quiescent current compared to 16µA for the MAX967ESA+T. This 4µA reduction is a direct result of the single-element configuration and provides a minor power consumption benefit in battery-powered or low-power applications.

Q: Are both substitute parts available in the same packaging format? A: Both MAX967ESA+T and MAX965ESA+T are supplied in Tape & Reel (TR) format, which is standard for production quantities. The original MAX967ESA-T was supplied in bulk packaging. Tape & Reel format is compatible with automated assembly equipment and is the industry standard for surface mount components.

Q: Do the substitute parts maintain RoHS and MSL compliance? A: Yes. Both MAX967ESA+T and MAX965ESA+T are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the compliance profile of the original MAX967ESA-T. No additional handling or storage precautions are required.
