Parameter Comparison

Engineering Selection Recommendations

MAX667EPA+ (Direct Successor)

The MAX667EPA+ is the active production equivalent of the MAX667EPA. Both parts share identical electrical specifications and package configuration. The MAX667EPA+ is manufactured to ROHS3 compliance standards, whereas the original MAX667EPA is RoHS non-compliant. The MAX667EPA+ is the primary recommended substitute for new designs and ongoing procurement of obsolete MAX667EPA inventory.

ADP667ANZ (Manufacturer-Recommended Alternative)

The ADP667ANZ is an Analog Devices manufacturer-recommended alternative that meets all core electrical and mechanical parameters of the MAX667EPA. This part is currently in active production status and carries ROHS3 compliance certification. The ADP667ANZ differs from the MAX667EPA in control features, omitting the Dropout Detector function while retaining Enable and Low Battery Detection capabilities. Selection of the ADP667ANZ requires verification that the Dropout Detector feature is not required in the target application.

Frequently Asked Questions (FAQ)

Q: Can MAX667EPA+ be used as a direct replacement for MAX667EPA?

A: Yes. The MAX667EPA+ is electrically and mechanically identical to the MAX667EPA. Both parts provide identical voltage regulation performance, output current capability, and thermal characteristics. The primary difference is compliance status: MAX667EPA+ meets ROHS3 standards while MAX667EPA does not.

Q: What is the key difference between MAX667EPA+ and ADP667ANZ?

A: Both parts meet the core electrical specifications of the MAX667EPA. The MAX667EPA+ retains all control features including Dropout Detector, Enable, and Low Battery Detection. The ADP667ANZ omits the Dropout Detector function but includes Enable and Low Battery Detection. Application requirements determine which substitute is appropriate.

Q: Are all substitutes compatible with existing PCB layouts designed for MAX667EPA?

A: Yes. All substitute parts use the 8-DIP (0.300", 7.62mm) package with Through Hole mounting, matching the original MAX667EPA footprint and pin configuration.

Q: What is the inventory status of these substitutes?

A: MAX667EPA+ has 2800 pieces in stock. ADP667ANZ has 3192 pieces in stock. Both are available as new original components.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process standards and material composition but does not alter electrical performance, voltage regulation characteristics, or output current capability.
