MAX663EPA Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The MAX663EPA is a linear voltage regulator IC from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) component. This device functions as a positive adjustable (fixed) output regulator with a single output capable of delivering 40mA. The MAX663EPA is currently listed as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The obsolete status necessitates evaluation of active alternative components that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX663EPA is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Output configuration (Positive)
• Output type (Adjustable/Fixed)
• Number of regulators (1)
• Voltage specifications: Input Max (16.5V), Output Min/Fixed (1.3V/5V), Output Max (16V)
• Voltage dropout (0.9V @ 40mA)
• Current output (40mA)
• Quiescent current (15 µA)
• Control features (Current Limit, Enable)
• Operating temperature range (-40°C ~ 85°C)

Mechanical Equivalence Criteria:

• Mounting type (Through Hole)
• Package type (8-DIP, 0.300", 7.62mm)
• Supplier device package (8-PDIP)

The MAX663EPA+ qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction is product status (Active vs. Obsolete) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX663EPA+ is the direct equivalent substitute for the MAX663EPA. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The MAX663EPA+ offers the following advantages for new designs and system support:

Product Status: The MAX663EPA+ maintains Active product status, ensuring continued availability and manufacturer support, whereas the MAX663EPA is Obsolete.

Compliance: The MAX663EPA+ is ROHS3 Compliant, meeting current environmental and regulatory requirements. The original MAX663EPA is RoHS non-compliant, which may present procurement and regulatory challenges in certain markets and applications.

Packaging: The MAX663EPA+ is supplied in Tube packaging, providing standard handling and storage conditions for production environments.

For applications currently using the MAX663EPA, direct substitution with the MAX663EPA+ is supported without circuit modification or re-qualification, provided that RoHS compliance requirements are satisfied by the system design.

Frequently Asked Questions (FAQ)

Q: Can the MAX663EPA+ be used as a direct replacement for the MAX663EPA?
