Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX6190AESA is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 1.25V
• Output current capability of 500 µA minimum
• Voltage tolerance of ±0.16% or better
• Temperature coefficient of 5 ppm/°C or lower
• Input voltage range of 2.5V to 12.6V minimum
• 8-SOIC surface mount package
• Operating temperature range of -40°C to 85°C

Parts meeting all these specifications are classified as direct functional equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The MAX6190AESA+ is a direct functional equivalent to the MAX6190AESA with identical electrical specifications across all critical parameters. The primary distinction is product lifecycle status: the MAX6190AESA is Obsolete while the MAX6190AESA+ is Active.

For new designs and ongoing production, the MAX6190AESA+ is the appropriate selection. This part maintains full electrical and mechanical compatibility while offering the advantage of Active product status and ROHS3 compliance, compared to the RoHS non-compliant status of the original part.

Both parts share identical 8-SOIC packaging, pinout, and electrical performance characteristics, enabling direct substitution at the component level without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can MAX6190AESA+ be used as a direct replacement for MAX6190AESA?

A: Yes. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and provide identical electrical performance: 1.25V fixed output, ±0.16% tolerance, 500 µA output current, 5 ppm/°C temperature coefficient, and 8-SOIC surface mount packaging. No circuit redesign is required.

Q: What is the difference between MAX6190AESA and MAX6190AESA+?

A: The primary differences are product status and compliance certification. MAX6190AESA is Obsolete and RoHS non-compliant, while MAX6190AESA+ is Active and ROHS3 compliant. Electrical specifications and package type are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: What is the supply availability difference?

A: MAX6190AESA has 2114 pieces in stock (Obsolete status). MAX6190AESA+ has 1860 pieces in stock (Active status). Active product status typically ensures better long-term availability.

Q: Does substitution require PCB layout changes?

A: No. Identical package type and pinout eliminate the need for PCB layout modifications.

Q: What compliance advantage does MAX6190AESA+ provide?

A: MAX6190AESA+ is ROHS3 compliant, meeting current environmental and regulatory requirements. MAX6190AESA is RoHS non-compliant, which may restrict use in certain applications or regions with RoHS mandates.
