Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX771CPA is determined by strict equivalence across the following critical parameters:

• Topology & Function: Boost regulator with step-up DC-DC controller functionality
• Output Characteristics: Single positive output, transistor driver output type
• Electrical Specifications: 3V ~ 16.5V supply voltage range, 300kHz switching frequency
• Package Compatibility: 8-DIP (0.300", 7.62mm) through-hole mounting
• Operating Temperature Range: 0°C ~ 70°C

The MAX771CPA+ qualifies as a direct substitute based on identical electrical performance, functional topology, and physical package specifications. Differences in product status and compliance certifications do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The MAX771CPA+ provides electrical and mechanical equivalence to the MAX771CPA with improved compliance status. The MAX771CPA+ is ROHS3 compliant, whereas the original MAX771CPA is RoHS non-compliant. Both parts maintain identical electrical performance specifications and physical package dimensions, ensuring direct interchangeability in existing circuit designs.

Selection between these parts should consider regulatory requirements and supply chain availability. The MAX771CPA+ is designated as "Not For New Designs," indicating limited future availability. The MAX771CPA is classified as "Obsolete," reflecting end-of-life status. For applications requiring long-term component availability or new design implementations, evaluation of alternative boost controller architectures from current product lines is warranted.

Frequently Asked Questions (FAQ)

Q: Can MAX771CPA+ be used as a direct replacement for MAX771CPA?

A: Yes. Both parts share identical electrical specifications, switching frequency, supply voltage range, output topology, and 8-DIP package dimensions. Physical and functional interchangeability is confirmed.

Q: What is the difference between MAX771CPA and MAX771CPA+?

A: The primary differences are product status and compliance certification. MAX771CPA+ is ROHS3 compliant with Tube packaging, while MAX771CPA is RoHS non-compliant. Electrical performance and package specifications are identical.

Q: Why is the MAX771CPA marked as Obsolete?

A: Obsolete status indicates the part has reached end-of-life and is no longer in active production. Existing inventory may be available through authorized distributors, but future availability is not guaranteed.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout and mounting specifications.

Q: What compliance certifications apply to these parts?

A: MAX771CPA+ is ROHS3 compliant and REACH unaffected. MAX771CPA is RoHS non-compliant but also REACH unaffected. Both carry EAR99 export classification.
