MAX875AESA Equivalent & Substitute Parts

Part Overview

The MAX875AESA is a Series Voltage Reference IC manufactured by Analog Devices Inc./Maxim Integrated, designed to provide a fixed 5V output with ±0.04% tolerance. This component operates as a precision voltage reference for power management applications, delivering 10 mA output current with low noise characteristics across the 0.1Hz to 10kHz frequency range.

The MAX875AESA is classified as obsolete. Identifying suitable substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications requiring this voltage reference functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX875AESA is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 5V
• Output current capability of 10 mA minimum
• Tolerance specification of ±0.04% or better
• Temperature coefficient of 7 ppm/°C or lower
• Noise performance within specified ranges (9 µVp-p at 0.1Hz to 10Hz; 14.5 µVrms at 10Hz to 10kHz)
• Input voltage range of 7V ~ 18V
• 8-SOIC surface mount package
• Operating temperature range of -40°C ~ 85°C

The MAX875AESA+ meets all electrical and mechanical parameters required for direct substitution. The primary distinction between these parts is product status and packaging configuration, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX875AESA+ is the direct functional equivalent of the MAX875AESA. Both parts deliver identical electrical performance across all specified parameters. The MAX875AESA+ is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The MAX875AESA, classified as obsolete, should be replaced with the MAX875AESA+ to ensure long-term supply chain stability and regulatory compliance.

For applications requiring the MAX875AESA, the MAX875AESA+ provides equivalent performance without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the MAX875AESA+ be used as a direct replacement for the MAX875AESA?

A: Yes. The MAX875AESA+ is electrically and mechanically identical to the MAX875AESA. All output voltage, current, tolerance, noise, and temperature specifications are equivalent. Both parts use the 8-SOIC surface mount package with identical pinout and footprint.

Q: What is the primary difference between these two parts?

A: The MAX875AESA+ is an active product with ROHS3 compliance certification, while the MAX875AESA is obsolete and RoHS non-compliant. Electrical performance is identical.

Q: Are there any package or mounting differences?

A: No. Both parts are supplied in 8-SOIC (0.154", 3.90mm Width) surface mount packages. PCB footprints and assembly processes are identical.

Q: Does the MAX875AESA+ require circuit design changes?

A: No. The MAX875AESA+ operates within the same input voltage range (7V ~ 18V), delivers the same output voltage (5V) and current (10 mA), and maintains identical temperature and noise specifications. No schematic or layout modifications are necessary.

Q: What is the inventory status of these parts?

A: The MAX875AESA has 1318 pieces in stock (obsolete status). The MAX875AESA+ has 1466 pieces in stock (active status).
