MAX967EUA Equivalent & Substitute Parts

Part Overview

The MAX967EUA is a dual-channel comparator with integrated voltage reference, featuring open-drain, rail-to-rail output configuration in an 8-uMAX/uSOP surface mount package. Manufactured by Analog Devices Inc./Maxim Integrated, this linear integrated circuit operates across a 1.6V to 5.5V supply range with low input offset voltage and minimal quiescent current consumption.

The MAX967EUA is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this comparator architecture.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX967EUA is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Output Type: Open-Drain, Rail-to-Rail
• Voltage - Supply Range: 1.6V ~ 5.5V
• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C
• Electrical Specifications: Input Offset Voltage, Input Bias Current, Quiescent Current, CMRR/PSRR, Propagation Delay, Hysteresis

Substitute Categories:

1. Direct Manufacturer Substitute (MAX967EUA+): Identical part number with packaging variant (Tube). Maintains all electrical and mechanical specifications. Product status is Active, providing improved supply availability compared to the obsolete MAX967EUA.

2. Parametric Equivalent (MAX965EUA+): Single-channel comparator variant with identical electrical performance across all specified parameters except Number of Elements (1 vs. 2) and Quiescent Current (12µA vs. 16µA). Maintains identical package, supply voltage range, output type, and thermal specifications. Suitable for applications requiring single-channel functionality with equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

MAX967EUA+ (Direct Substitute): The MAX967EUA+ is the primary recommended substitute for the obsolete MAX967EUA. This part maintains identical electrical specifications, package configuration, and functional characteristics while offering Active product status. The transition from Tube packaging (MAX967EUA+) versus the original packaging variant presents no functional impact. Both parts comply with ROHS3 and REACH requirements, ensuring regulatory alignment for new designs and production continuity.

MAX965EUA+ (Parametric Equivalent): The MAX965EUA+ is suitable for applications where single-channel comparator functionality is sufficient. This part delivers equivalent electrical performance across all critical parameters including input offset voltage, input bias current, propagation delay, hysteresis, and output characteristics. The reduced quiescent current (12µA vs. 16µA) provides a marginal power consumption advantage. Selection of MAX965EUA+ requires circuit-level verification that single-channel operation meets application requirements. Both parts maintain identical compliance certifications and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can MAX967EUA+ directly replace MAX967EUA in existing designs? A: Yes. MAX967EUA+ maintains identical electrical specifications, package dimensions, and functional performance. The only difference is product status (Active vs. Obsolete) and packaging format (Tube). No circuit modifications are required.

Q: What is the primary difference between MAX967EUA and MAX965EUA+? A: The MAX967EUA contains two comparator elements, while MAX965EUA+ contains one. Both share identical electrical performance specifications including input offset voltage, propagation delay, hysteresis, and output type. The MAX965EUA+ also operates at lower quiescent current (12µA vs. 16µA).

Q: Is MAX965EUA+ compatible with MAX967EUA pinout? A: Both parts use the same 8-TSSOP/8-MSOP package with identical physical dimensions (0.118", 3.00mm Width). However, internal pinout configuration differs due to the single-channel versus dual-channel architecture. Circuit-level verification is required before substitution.

Q: Do all substitute parts meet the same compliance requirements? A: Yes. MAX967EUA+, MAX965EUA+, and the original MAX967EUA all comply with ROHS3 and REACH requirements. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no moisture-related handling restrictions.

Q: What is the operating temperature range for substitute parts? A: All parts operate across -40°C to 85°C, maintaining identical thermal specifications for industrial and commercial applications.

Q: Are there inventory considerations when selecting substitutes? A: MAX967EUA+ has 3297 units in stock, while MAX965EUA+ has 4019 units available. Both offer superior availability compared to the obsolete MAX967EUA (3900 units, end-of-life status).
