Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5041BEAI is determined by strict equivalence across the following critical parameters:

• Package / Case: 28-SSOP form factor with identical 0.209" width and 5.30mm dimensions
• Topology and Function: Buck regulator with step-down configuration and positive output
• Output Configuration: Two outputs with two-phase operation
• Voltage Supply Range: 4.75V to 28V input capability
• Switching Frequency: 250kHz and 500kHz operation modes
• Synchronous Rectifier: Integrated synchronous rectification capability
• Control Features: Enable and phase control functionality
• Operating Temperature Range: -40°C to 85°C
• Compliance: ROHS3 compliant, MSL 1 rating

The MAX5041EAI+ meets all these criteria and qualifies as a direct substitute for the obsolete MAX5041BEAI.

Parameter Comparison

Engineering Selection Recommendations

The MAX5041EAI+ is the direct substitute for the obsolete MAX5041BEAI. Both components share identical electrical specifications, package form factor, and compliance certifications. The primary distinction is product status: the MAX5041BEAI is obsolete while the MAX5041EAI+ maintains active product status with current manufacturing and distribution support.

For new designs or ongoing production requiring MAX5041BEAI functionality, the MAX5041EAI+ provides equivalent performance with the advantage of active availability and supply chain continuity. Both components maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.
