Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX750ACSA is determined by strict equivalence across the following critical parameters:

• Input voltage range: 4V to 11V
• Output voltage adjustability: 1.22V to 11V
• Output current capacity: 450mA
• Switching frequency: 170kHz
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Topology: Buck (step-down)
• Output configuration: Positive adjustable
• Number of outputs: Single output
• Synchronous rectifier capability: Not required

The MAX750ACSA+ meets all electrical and mechanical specifications required for direct substitution. The primary distinction between the main part and its substitute relates to product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MAX750ACSA+ is the direct functional equivalent of the MAX750ACSA. Both devices share identical electrical specifications, switching characteristics, and package geometry. The MAX750ACSA+ is the preferred selection for new designs and production applications due to its active product status and ROHS3 compliance. The obsolete status of the MAX750ACSA restricts its availability for future procurement and may present supply chain constraints.

For applications requiring the MAX750ACSA, transition to the MAX750ACSA+ is supported by complete electrical and mechanical compatibility. No circuit redesign or board layout modification is required.

Frequently Asked Questions (FAQ)

Q: Can the MAX750ACSA+ be used as a direct replacement for the MAX750ACSA?

A: Yes. The MAX750ACSA+ provides identical electrical performance and package compatibility. Both devices operate with the same input voltage range (4V to 11V), output voltage adjustability (1.22V to 11V), output current (450mA), and switching frequency (170kHz). The 8-SOIC package dimensions are identical, permitting direct PCB substitution without layout modification.

Q: What is the primary difference between these two parts?

A: The MAX750ACSA is classified as obsolete, while the MAX750ACSA+ maintains active product status. Additionally, the MAX750ACSA+ is ROHS3 compliant, whereas the MAX750ACSA is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any packaging differences?

A: Both devices use the 8-SOIC (0.154", 3.90mm Width) surface mount package. No packaging variation exists between the two parts.

Q: What certifications apply to these devices?

A: Both the MAX750ACSA and MAX750ACSA+ carry REACH Unaffected status and EAR99 export classification. The MAX750ACSA+ additionally meets ROHS3 compliance requirements. Both devices have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited).

Q: Is the MAX750ACSA still available for purchase?

A: The MAX750ACSA is classified as obsolete. Procurement should transition to the MAX750ACSA+, which is actively manufactured and distributed by Analog Devices Inc./Maxim Integrated.
