MAX9051AESA+ Equivalent & Substitute Parts

Part Overview

The MAX9051AESA+ is a single-channel comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This CMOS, push-pull, rail-to-rail comparator with TTL output operates across a 2.7V to 5.5V supply range and is housed in an 8-SOIC surface mount package. The device is currently in active production status and is ROHS3 compliant. Identifying equivalent and substitute parts is necessary when addressing supply chain constraints, lead time requirements, or specific application compatibility needs while maintaining electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

Substitution of the MAX9051AESA+ is determined by strict equivalence across the following critical parameters:

• Output Type: CMOS, Push-Pull, Rail-to-Rail, TTL configuration
• Supply Voltage Range: 2.7V ~ 5.5V single supply operation
• Package Type: 8-SOIC surface mount form factor
• Functional Architecture: Single-channel comparator with integrated voltage reference
• Electrical Performance: Input offset voltage, input bias current, output current, quiescent current, CMRR/PSRR, propagation delay, and hysteresis specifications
• Environmental Compliance: ROHS3 compliance and MSL rating

The MAX9051AESA+ represents the parametric equivalent within the MAX9051 base product family. No alternative manufacturer part numbers meeting all specified electrical and mechanical parameters are provided in the substitute list.

Parameter Comparison

Engineering Selection Recommendations

The MAX9051AESA+ maintains active production status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), supporting deployment in standard manufacturing and storage environments without special handling requirements. Selection of this comparator with voltage reference is appropriate for applications requiring single-channel comparison with integrated reference functionality across the 2.7V to 5.5V supply range in 8-SOIC surface mount configurations. The device's CMOS push-pull rail-to-rail TTL output architecture provides direct logic interface compatibility. All electrical specifications, including 5mV maximum input offset voltage, 1pA maximum input bias current, 450ns maximum propagation delay, and ±3mV hysteresis, are maintained across equivalent part selections.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX9051AESA+?

A: A valid substitute must maintain identical electrical specifications across output type (CMOS, Push-Pull, Rail-to-Rail, TTL), supply voltage range (2.7V ~ 5.5V), input offset voltage (5mV @ 5V maximum), input bias current (1pA @ 5V maximum), output current (8mA typical), quiescent current (72µA maximum), CMRR/PSRR (80dB typical), propagation delay (450ns maximum), hysteresis (±3mV), operating temperature range (-40°C ~ 85°C), and package type (8-SOIC surface mount).

Q: Can the MAX9051AESA+ be replaced with a different package variant?

A: No. The 8-SOIC (0.154", 3.90mm Width) surface mount package is a critical mechanical specification. Substitution requires identical package type to ensure PCB layout compatibility, thermal performance, and assembly process alignment.

Q: Is the MAX9051AESA+ suitable for applications requiring extended temperature operation beyond -40°C ~ 85°C?

A: The MAX9051AESA+ is specified for -40°C ~ 85°C operation. Applications requiring extended temperature ranges require evaluation of alternative device grades or manufacturers outside the scope of this equivalency reference.

Q: What is the significance of the ROHS3 compliance and MSL 1 rating?

A: ROHS3 compliance indicates the device meets Restriction of Hazardous Substances directives for lead-free manufacturing. MSL 1 (Unlimited) indicates the device has unlimited shelf life and does not require special moisture control during storage or handling, supporting standard manufacturing logistics.

Q: Are there functional differences between the main part and substitute listings?

A: No. The provided substitute represents parametric equivalence with identical electrical performance, output architecture, supply voltage range, and package specifications.
