Substitute Part Grouping Explanation

Substitution eligibility for the MAX1742EEE is determined by strict equivalence across the following critical parameters:

• Input voltage range: 3V to 5.5V
• Output voltage configuration: Adjustable (Programmable) with 1.1V, 1.5V, 1.8V, 2.5V options
• Output current capability: 1A minimum
• Switching frequency: 1MHz
• Synchronous rectifier: Present
• Package type: 16-SSOP (0.154", 3.90mm Width)
• Operating temperature range: -40°C to 85°C
• Surface mount configuration

The MAX1742EEE+ qualifies as a direct substitute based on identical electrical specifications, package dimensions, and functional characteristics. The primary distinction is product status: MAX1742EEE+ is active production, whereas MAX1742EEE is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MAX1742EEE+ is the direct substitute for MAX1742EEE applications. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in circuit implementations.
