Substitute Part Grouping Explanation

Substitution eligibility for the MAX4273EEE is determined by strict equivalence across the following critical parameters:

• Identical functional classification: Single-channel hot swap controller for general-purpose applications
• Matching electrical specifications: 2.7V to 13.2V supply voltage range, 600 µA supply current, -40°C to 85°C operating temperature
• Identical package and pinout: 16-SSOP (0.154", 3.90mm Width) surface mount configuration
• Equivalent feature set: OVP and UVLO protection with programmable auto retry, circuit breaker, current limit, fault timeout, and latched fault capabilities
• Same base product number: MAX4273 series designation

The MAX4273EEE+ qualifies as a direct substitute based on complete alignment with all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The MAX4273EEE+ is the direct functional equivalent of the MAX4273EEE. Both parts share identical electrical specifications, package configuration, and feature sets. The primary distinction is product lifecycle status: the MAX4273EEE is obsolete, while the MAX4273EEE+ maintains active production status.

The MAX4273EEE+ additionally carries ROHS3 compliance certification, whereas the original MAX4273EEE is RoHS non-compliant. For applications subject to RoHS regulatory requirements or environmental compliance mandates, the MAX4273EEE+ provides the necessary certification alignment while maintaining complete functional equivalence.

Selection of the MAX4273EEE+ is appropriate for new designs, design revisions, and supply chain continuity planning for existing applications currently using the MAX4273EEE.

Frequently Asked Questions (FAQ)

Q: Can the MAX4273EEE+ be used as a direct replacement for the MAX4273EEE in existing designs?

A: Yes. The MAX4273EEE+ is electrically and functionally identical to the MAX4273EEE across all specified parameters, including supply voltage range, operating temperature, package configuration, and programmable feature set. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference between these parts?

A: The MAX4273EEE carries obsolete status, indicating discontinued production and limited availability. The MAX4273EEE+ maintains active production status, ensuring reliable long-term supply and availability for current and future applications.

Q: How does RoHS compliance affect part selection?

A: The MAX4273EEE is RoHS non-compliant, while the MAX4273EEE+ is ROHS3 compliant. Applications subject to RoHS regulatory requirements, environmental standards, or customer specifications mandating RoHS compliance must use the MAX4273EEE+. For applications without RoHS requirements, both parts are functionally equivalent.

Q: Are the packaging and pinout configurations identical?

A: Yes. Both the MAX4273EEE and MAX4273EEE+ use the 16-SSOP (0.154", 3.90mm Width) surface mount package with identical pinout. PCB layouts and footprints require no modification for substitution.

Q: What programmable features are available in both parts?

A: Both parts support identical programmable capabilities: auto retry, circuit breaker, current limit, fault timeout, and latched fault functions. Application-specific configuration remains consistent between the two parts.
