MAX6190CESA Equivalent & Substitute Parts

Part Overview

The MAX6190CESA is a Series Voltage Reference IC manufactured by Analog Devices Inc./Maxim Integrated, designed to provide a fixed 1.25V output with ±0.48% tolerance. This component operates as a precision voltage reference for power management applications, accepting input voltages between 2.5V and 12.6V while delivering 500 µA output current. The part is classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure long-term supply availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX6190CESA is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 1.25V
• Output current capability of 500 µA
• Tolerance specification of ±0.48%
• Temperature coefficient of 25 ppm/°C
• Input voltage range of 2.5V ~ 12.6V
• Supply current of 35 µA
• Operating temperature range of -40°C ~ 85°C
• 8-SOIC surface mount package configuration

The MAX6190CESA+ meets all these requirements and qualifies as a parametric equivalent. The primary distinction between the main part and its substitute is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX6190CESA+ is the direct parametric equivalent for the obsolete MAX6190CESA. All electrical and mechanical specifications are identical, ensuring pin-for-pin and functional compatibility in existing circuit designs.

Selection of MAX6190CESA+ is supported by two additional factors:

1. Active Product Status: The MAX6190CESA+ maintains active production status, ensuring continued availability and supply chain reliability.

2. Compliance Certification: The MAX6190CESA+ achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in most markets.

No design modifications, PCB layout changes, or circuit alterations are required when transitioning from MAX6190CESA to MAX6190CESA+.

Frequently Asked Questions (FAQ)

Q: Can MAX6190CESA+ be used as a direct replacement for MAX6190CESA?

A: Yes. The MAX6190CESA+ is electrically and mechanically identical to the MAX6190CESA across all specified parameters. It is a direct pin-for-pin substitute requiring no circuit modifications.

Q: What is the primary reason to substitute MAX6190CESA with MAX6190CESA+?

A: The MAX6190CESA is obsolete, while MAX6190CESA+ maintains active production status. This ensures long-term component availability and supply chain continuity.

Q: Are there any compliance differences between the two parts?

A: Yes. The MAX6190CESA+ is ROHS3 compliant, whereas the original MAX6190CESA is RoHS non-compliant. This represents an improvement in regulatory alignment.

Q: Will the packaging differ between MAX6190CESA and MAX6190CESA+?

A: Both parts use the same 8-SOIC surface mount package. The only packaging difference is that MAX6190CESA+ is supplied in Tube packaging, whereas the original part packaging is not specified in the available data.

Q: Are the electrical performance characteristics identical?

A: Yes. Output voltage, current, tolerance, temperature coefficient, noise specifications, input voltage range, supply current, and operating temperature range are identical between both parts.
