MAX6250ACSA Equivalent & Substitute Parts

Part Overview

The MAX6250ACSA is a Series, Buried Zener Voltage Reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed 5V output with ±0.02% tolerance and is designed for precision voltage reference applications requiring low noise and stable output across a wide input voltage range of 8V to 36V. The device is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX6250ACSA is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 5V
• Output current capability of 15 mA minimum
• Voltage tolerance of ±0.02% or better
• Temperature coefficient of 2 ppm/°C or lower
• Input voltage range of 8V to 36V minimum
• 8-SOIC surface mount package
• Noise specifications: 3 µVp-p (0.1Hz to 10Hz) and 2.5 µVrms (10Hz to 10kHz)

The MAX6250ACSA+ meets all these criteria and is therefore a direct functional equivalent. The primary distinction between the main part and its substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX6250ACSA+ is the direct substitute for the MAX6250ACSA. Both parts are electrically and mechanically identical across all functional parameters. The MAX6250ACSA+ is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The original MAX6250ACSA, classified as obsolete, should be replaced with the MAX6250ACSA+ to ensure long-term supply chain continuity and regulatory compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can MAX6250ACSA+ be used as a direct replacement for MAX6250ACSA?

A: Yes. Both parts are electrically and mechanically identical. All electrical specifications, including output voltage, tolerance, temperature coefficient, noise characteristics, and input voltage range, are identical. The 8-SOIC package dimensions and pinout are the same.

Q: What is the difference between MAX6250ACSA and MAX6250ACSA+?

A: The primary differences are product status and compliance. MAX6250ACSA is obsolete, while MAX6250ACSA+ is active. MAX6250ACSA+ is ROHS3 compliant, whereas MAX6250ACSA is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). Pinout and mounting type (surface mount) are identical.

Q: What is the moisture sensitivity level for these parts?

A: Both MAX6250ACSA and MAX6250ACSA+ have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Is MAX6250ACSA+ suitable for applications requiring RoHS compliance?

A: Yes. MAX6250ACSA+ is ROHS3 compliant and meets current environmental regulations. MAX6250ACSA is not RoHS compliant and should not be used in applications with RoHS requirements.
