MAX901BESE+ Equivalent & Substitute Parts

Part Overview

The MAX901BESE+ is a general-purpose comparator IC manufactured by Analog Devices Inc./Maxim Integrated. This 4-element comparator features TTL output configuration and operates across single or dual supply voltages (5V ~ 10V, ±2.5V ~ 5V). The device is actively produced and widely used in signal conditioning, threshold detection, and level comparison applications. Finding equivalent parts ensures design flexibility, supply chain continuity, and cost optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MAX901BESE+ is determined by strict alignment across the following critical parameters:

• Functional Type: General-purpose comparator with 4 independent elements
• Output Configuration: TTL-compatible output stage
• Supply Voltage Range: 5V ~ 10V single supply or ±2.5V ~ 5V dual supply operation
• Electrical Performance: Input offset voltage ≤ 4mV @ ±5V, input bias current ≤ 10µA @ ±5V, CMRR ≥ 82.5dB, PSRR ≥ 80dB
• Package Specification: 16-SOIC surface-mount package (0.154" width, 3.90mm)
• Temperature Range: -40°C to 85°C operating window
• Compliance Requirements: ROHS3 compliance, MSL Level 1

Parts meeting all these criteria are electrically and mechanically interchangeable without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The MAX901BESE+ maintains active product status with full ROHS3 compliance and MSL Level 1 rating, indicating unrestricted moisture sensitivity handling. Selection of equivalent parts should prioritize devices with identical active status and matching compliance certifications to ensure long-term supply availability and regulatory alignment. The 16-SOIC surface-mount package and TTL output configuration are fixed requirements for direct substitution without PCB redesign. Supply voltage flexibility (single or dual rail operation) and the specified electrical performance envelope (input offset, bias current, CMRR, PSRR) define the functional interchangeability boundary.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the MAX901BESE+?

A: A substitute must match all critical parameters: 4-element general-purpose comparator with TTL output, 5V ~ 10V or ±2.5V ~ 5V supply operation, input offset ≤ 4mV @ ±5V, input bias current ≤ 10µA @ ±5V, CMRR ≥ 82.5dB, PSRR ≥ 80dB, 16-SOIC package, and -40°C to 85°C temperature range.

Q: Can I use a different package type as a substitute?

A: No. The 16-SOIC (0.154", 3.90mm width) surface-mount package is a fixed requirement. Different package types require PCB layout changes and are not considered direct substitutes.

Q: Does the substitute need to have the same product status?

A: Yes. Active product status ensures ongoing manufacturing support and supply chain stability. Substitutes with different status classifications may face availability or support limitations.

Q: Are there compliance considerations for substitution?

A: Yes. The substitute must maintain ROHS3 compliance and MSL Level 1 rating to meet regulatory requirements and handling specifications equivalent to the original part.

Q: What if I need a comparator with different output type (CMOS instead of TTL)?

A: TTL output type is a core functional requirement for this application. Devices with different output configurations are not substitutes and require circuit redesign.
