MAX6192AESA Equivalent & Substitute Parts

Part Overview

The MAX6192AESA is a series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated, designed to provide a fixed 2.5V output with ±0.08% tolerance. This component operates as a precision voltage reference in power management applications, featuring low noise performance and wide input voltage range compatibility. The MAX6192AESA is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute components must maintain electrical compatibility across output voltage, tolerance, temperature coefficient, noise characteristics, and input voltage specifications while accommodating packaging and product status considerations.

Substitute Part Grouping Explanation

Substitute parts for the MAX6192AESA are selected based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following allowed parameters:

Fixed output voltage of 2.5V
Output tolerance of ±0.08%
8-SOIC surface mount package with identical physical dimensions
Input voltage range compatibility (minimum 2.7V operation required)
Operating temperature range support (-40°C minimum)

The MAX6192AESA+ serves as a direct packaging variant substitute with identical electrical specifications but improved product status (Active vs. Obsolete) and RoHS3 compliance. The ADR291ERZ and ADR291ERZ-REEL7 represent manufacturer-recommended alternatives from the XFET® series, offering enhanced performance characteristics including higher output current capability (5mA vs. 500µA), improved temperature coefficient (8ppm/°C vs. 5ppm/°C), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C), while maintaining the same output voltage, tolerance, and package form factor.

Engineering Selection Recommendations

For applications currently using the MAX6192AESA, the MAX6192AESA+ is the primary direct substitute, offering identical electrical performance with the advantage of Active product status and ROHS3 compliance. This variant eliminates obsolescence risk while maintaining full backward compatibility.

The ADR291ERZ and ADR291ERZ-REEL7 are suitable alternatives when higher output current capability (5mA vs. 500µA) and extended temperature range (-40°C to 125°C) are beneficial to system design. These parts maintain the required 2.5V output voltage and ±0.08% tolerance specification. The ADR291ERZ is supplied in standard tube packaging, while ADR291ERZ-REEL7 is supplied in cut tape and Digi-Reel format for automated assembly environments.

All substitute options are ROHS3 compliant and carry Active product status, ensuring long-term availability and regulatory compliance for new designs.

Frequently Asked Questions (FAQ)

Q: Can MAX6192AESA+ be used as a direct replacement for MAX6192AESA?

A: Yes. The MAX6192AESA+ maintains identical electrical specifications including 2.5V output voltage, ±0.08% tolerance, 500µA output current, and 8-SOIC package dimensions. The primary differences are improved product status (Active vs. Obsolete) and ROHS3 compliance.

Q: What are the key differences between MAX6192AESA and ADR291ERZ?

A: Both parts provide 2.5V output with ±0.08% tolerance in 8-SOIC packages. The ADR291ERZ offers higher output current (5mA vs. 500µA), lower supply current (15µA vs. 35µA), superior noise performance (8µVp-p vs. 60µVp-p at 0.1Hz-10Hz), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C). Temperature coefficient is slightly higher at 8ppm/°C versus 5ppm/°C.

Q: Are packaging differences between ADR291ERZ and ADR291ERZ-REEL7 significant?

A: Both parts are electrically identical. ADR291ERZ is supplied in tube packaging for manual handling, while ADR291ERZ-REEL7 is supplied in cut tape and Digi-Reel format optimized for automated pick-and-place assembly. Selection depends on production assembly method and volume requirements.

Q: What input voltage range must be maintained for substitution compatibility?

A: The MAX6192AESA operates from 2.7V to 12.6V input. The ADR291ERZ series requires minimum 3V input, establishing a 3V to 12.6V compatible operating window for direct substitution in existing designs.

Q: Are all substitute parts RoHS compliant?

A: Yes. MAX6192AESA+ is ROHS3 compliant. ADR291ERZ and ADR291ERZ-REEL7 are both ROHS3 compliant. The original MAX6192AESA is RoHS non-compliant.
