MAX883CSA-T Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The MAX883CSA-T is a linear voltage regulator IC from Analog Devices Inc./Maxim Integrated, designed for positive adjustable (fixed) output applications with 200mA current capability in an 8-SOIC surface mount package. This device provides regulated power management with integrated protection features including over-current, over-temperature, and reverse polarity protection.

The MAX883CSA-T is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this regulator.

Substitute Part Grouping Explanation

Substitution of the MAX883CSA-T is determined by strict equivalence across the following critical parameters:

Output configuration (Positive)
Output type (Adjustable/Fixed)
Number of regulators (1)
Maximum input voltage (11.5V)
Output voltage range (1.25V to 11V)
Maximum dropout voltage (0.44V @ 200mA)
Output current capability (200mA)
Quiescent current (15 µA)
Control features (Enable, Low Battery Detection)
Protection features (Over Current, Over Temperature, Reverse Polarity)
Operating temperature range (0°C ~ 70°C)
Package type (8-SOIC)

The MAX883CSA+T meets all these criteria and qualifies as a parametric equivalent. The primary distinction between the main part and substitute is packaging format (tube vs. tape & reel) and product status (obsolete vs. active).

Engineering Selection Recommendations

The MAX883CSA+T is a direct parametric equivalent to the MAX883CSA-T across all electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: The MAX883CSA+T carries an active product status, ensuring ongoing manufacturer support and availability. The MAX883CSA-T is obsolete and subject to supply constraints.

Compliance: The MAX883CSA+T is ROHS3 compliant, meeting current environmental and regulatory requirements. The MAX883CSA-T is RoHS non-compliant, which may present compliance challenges in new designs or regulated applications.

Packaging: The MAX883CSA+T is supplied in tape & reel format, suitable for automated assembly processes. The MAX883CSA-T is supplied in tube format. Packaging selection depends on production volume and assembly methodology.

For new designs or ongoing production requiring regulatory compliance, the MAX883CSA+T is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part is electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the MAX883CSA-T and MAX883CSA+T pin-compatible?

A: Yes. Both devices use the 8-SOIC package with identical pinout and electrical characteristics. They are direct mechanical and electrical substitutes.

Q: What is the difference between the MAX883CSA-T and MAX883CSA+T?

A: The primary differences are product status (obsolete vs. active), packaging format (tube vs. tape & reel), and RoHS compliance status (non-compliant vs. ROHS3 compliant). All electrical and thermal specifications are identical.

Q: Can I use the MAX883CSA+T as a replacement for the MAX883CSA-T in existing designs?

A: Yes. The MAX883CSA+T is a direct parametric equivalent and can be used as a drop-in replacement without circuit modifications. Verify that your assembly process can accommodate tape & reel packaging if switching from tube format.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical electrical characteristics and protection features.

Q: What output voltage configurations are available for the MAX883 series?

A: The MAX883 supports adjustable and fixed output configurations. The output voltage range is 1.25V to 11V, with common fixed outputs at 5V. Specific output voltage is determined by external resistor networks or internal configuration.

Q: Is the 8-SOIC package suitable for high-volume automated assembly?

A: Yes. The 8-SOIC package is standard for surface mount assembly. The MAX883CSA+T in tape & reel format is optimized for automated pick-and-place equipment. The MAX883CSA-T in tube format requires manual or semi-automated handling.
