MAX9012EUA-T Equivalent & Substitute Parts

Part Overview

The MAX9012EUA-T is a dual general-purpose comparator IC manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-TSSOP/8-MSOP surface-mount package. This device is designed for TTL-output comparison applications requiring low propagation delay and precision input offset specifications. The MAX9012EUA-T is currently classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. Substitute parts must maintain identical electrical performance and package compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9012EUA-T is determined by strict equivalence across the following critical parameters:

• Dual general-purpose comparator architecture with TTL output stage
• Supply voltage range of 4.5V ~ 5.5V
• Input offset voltage maximum of 3mV @ 5.5V
• Input bias current maximum of 0.5µA @ 5V
• Output current capability of 40mA typical
• Quiescent current maximum of 4.2mA
• CMRR and PSRR specifications of 95dB and 82dB respectively
• Propagation delay maximum of 9ns
• Operating temperature range of -40°C ~ 85°C
• 8-TSSOP/8-MSOP surface-mount package with 0.118" (3.00mm) width
• ROHS3 compliance and MSL Level 1 rating

The MAX9012EUA+T meets all these criteria and is classified as an active product, making it a direct parametric equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The MAX9012EUA+T is the direct substitute for the obsolete MAX9012EUA-T. Both parts share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: the MAX9012EUA+T is actively manufactured and available, while the MAX9012EUA-T is obsolete. Selection of the MAX9012EUA+T ensures continued access to supply, compliance with current regulatory requirements (ROHS3, REACH), and equivalent performance in all application contexts. The packaging difference (Cut Tape & Digi-Reel® for the substitute versus standard packaging for the main part) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MAX9012EUA+T directly replace the MAX9012EUA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The MAX9012EUA+T is pin-compatible, operates within the same voltage and temperature ranges, and delivers identical performance characteristics. No circuit modifications are required.

Q: What is the difference between MAX9012EUA-T and MAX9012EUA+T?

A: The difference is in the suffix designation and product status. The MAX9012EUA-T is obsolete, while the MAX9012EUA+T is an active product from the same manufacturer. The electrical specifications and package are identical. The "+T" suffix indicates the active variant with standard tape-and-reel packaging.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 ratings. Regulatory and environmental compliance is equivalent.

Q: What is the package compatibility?

A: Both parts use the 8-TSSOP/8-MSOP surface-mount package with a 0.118" (3.00mm) width. PCB footprints, solder pad layouts, and mounting procedures are identical. No PCB redesign is necessary.

Q: Why is the MAX9012EUA-T marked as obsolete?

A: Product obsolescence is a manufacturer lifecycle decision. The MAX9012EUA+T remains in active production and is the recommended source for new designs and ongoing production requirements.
