ADP3367ARZ Equivalent & Substitute Parts

Part Overview

The ADP3367ARZ is an active linear voltage regulator IC from Analog Devices Inc., classified as a Power Management (PMIC) component. This positive adjustable/fixed output regulator delivers 300mA maximum output current in an 8-SOIC surface mount package. The device is currently in active production status with 1,390 units in stock.

Substitute parts are necessary when the ADP3367ARZ becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for compatible alternatives with equivalent electrical performance within defined operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADP3367ARZ is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output configuration must be positive
• Output type must be adjustable (fixed)
• Voltage input maximum must be ≥16.5V
• Voltage output range must encompass 1.3V to 16V
• Package / Case must be 8-SOIC (0.154", 3.90mm Width)
• Mounting type must be surface mount

Operational Constraints:

• Current output capacity must be ≥300mA for direct substitution
• Operating temperature range must support the application requirements
• Voltage dropout specifications must be acceptable for the circuit design

The MAX667 series parts (MAX667CSA+, MAX667CSA+T, MAX667ESA+, MAX667ESA+T) share identical electrical specifications for voltage input/output ranges and package configuration. However, these parts deliver 250mA maximum output current, which is lower than the ADP3367ARZ's 300mA rating. These parts are suitable only for applications where the required output current does not exceed 250mA.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, meeting regulatory requirements equivalent to the ADP3367ARZ.

For applications requiring 300mA output current: The ADP3367ARZ is the only part in this comparison that meets the full 300mA specification. No direct substitution is available within the MAX667 series.

For applications with output current requirements ≤250mA: The MAX667 series parts are electrically compatible. Selection between variants depends on packaging and temperature range requirements:

• MAX667ESA+ and MAX667ESA+T support the full -40°C ~ 85°C operating temperature range, matching the ADP3367ARZ thermal specification.
• MAX667CSA+ and MAX667CSA+T operate within 0°C ~ 70°C, suitable only for commercial temperature applications.
• Tube packaging (MAX667CSA+, MAX667ESA+) is appropriate for manual assembly and lower-volume production.
• Cut Tape (CT) & Digi-Reel® packaging (MAX667CSA+T, MAX667ESA+T) is optimized for automated pick-and-place assembly.

Frequently Asked Questions (FAQ)

Q: Can MAX667 parts directly replace the ADP3367ARZ in all applications?

A: No. The MAX667 series delivers 250mA maximum output current, while the ADP3367ARZ delivers 300mA. Substitution is valid only when the circuit design requires ≤250mA output current.

Q: What is the difference between MAX667ESA+ and MAX667ESA+T?

A: Both parts are electrically identical. The difference is packaging format: MAX667ESA+ uses Tube packaging, while MAX667ESA+T uses Cut Tape (CT) & Digi-Reel® packaging. Selection depends on assembly process requirements.

Q: Can I use MAX667CSA+ in a circuit designed for -40°C operation?

A: No. MAX667CSA+ operates within 0°C ~ 70°C only. For applications requiring -40°C ~ 85°C operation, use MAX667ESA+ or MAX667ESA+T.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the ADP3367ARZ and all MAX667 variants, are ROHS3 compliant.

Q: What is the significance of the voltage dropout difference between ADP3367ARZ and MAX667 parts?

A: The ADP3367ARZ specifies 0.5V dropout at 300mA, while MAX667 parts specify 0.35V dropout at 200mA. These specifications reflect different output current ratings and are not directly comparable. Dropout performance at equivalent current levels must be verified in the respective datasheets.
