MAX901ACSE+ Equivalent & Substitute Parts

Part Overview

The MAX901ACSE+ is a general-purpose comparator IC manufactured by Analog Devices Inc./Maxim Integrated. This 4-element comparator features TTL output configuration and operates across a supply voltage range of 5V to 10V (single supply) or ±2.5V to ±5V (dual supply). The device is housed in a 16-SOIC surface-mount package and is actively produced with ROHS3 compliance. Alternative components are evaluated based on matching electrical specifications, package compatibility, and functional equivalence for direct circuit substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX901ACSE+ is determined by the following critical parameters:

• Number of comparator elements: 4
• Output configuration: TTL
• Supply voltage range: 5V ~ 10V (single), ±2.5V ~ 5V (dual)
• Input offset voltage: 2mV maximum at ±5V
• Input bias current: 6µA maximum at ±5V
• Package type: 16-SOIC surface mount
• Operating temperature range: 0°C ~ 70°C
• Compliance certifications: ROHS3, REACH Unaffected

Parts meeting all these electrical and mechanical specifications are classified as direct equivalents. The MAX901ACSE+ itself represents the primary reference for this substitution group.

Parameter Comparison

Engineering Selection Recommendations

The MAX901ACSE+ is an active product with full ROHS3 compliance and REACH unaffected status, making it suitable for current production applications. When sourcing this component, verify that substitute parts maintain identical electrical specifications, particularly the 2mV input offset voltage and 6µA input bias current specifications, as these parameters directly affect circuit performance in precision comparison applications.

Package compatibility is mandatory: only 16-SOIC surface-mount devices with 0.154" width (3.90mm) are acceptable for direct PCB substitution without layout modifications. Supply voltage range and TTL output configuration must match exactly to ensure proper circuit operation and signal integrity.

Frequently Asked Questions (FAQ)

Q: Can I substitute the MAX901ACSE+ with a different comparator from another manufacturer?

A: Substitution is limited to parts matching all specified electrical parameters: 4-element TTL output comparator, 5V ~ 10V / ±2.5V ~ 5V supply range, 2mV input offset voltage, 6µA input bias current, and 16-SOIC package. Only components meeting these exact specifications are direct equivalents.

Q: What is the significance of the 16-SOIC package specification?

A: The 16-SOIC (0.154", 3.90mm width) package defines the physical footprint and pin configuration. This specification ensures mechanical compatibility with existing PCB layouts and automated assembly equipment. Deviations in package type require circuit board redesign.

Q: Are there any compliance considerations for substitute parts?

A: Yes. Substitute parts must maintain ROHS3 compliance and REACH unaffected status to meet regulatory requirements for production applications. MSL rating of 1 (unlimited moisture sensitivity level) applies to all qualified substitutes.

Q: How do input offset voltage and input bias current affect substitution decisions?

A: These parameters directly impact circuit accuracy and performance. The MAX901ACSE+ specifies 2mV maximum input offset voltage and 6µA maximum input bias current at ±5V. Substitute parts must match these specifications exactly to maintain circuit performance and signal fidelity in comparison applications.

Q: Is the operating temperature range 0°C ~ 70°C a limiting factor for substitution?

A: Yes. The specified operating temperature range defines the thermal environment in which the component functions reliably. Substitute parts must support the identical 0°C ~ 70°C range. Applications requiring extended temperature operation require components with different temperature ratings.
