Engineering Selection Recommendations
The MAX4558ESE+ is a direct functional and mechanical equivalent to the MAX4558ESE. Both components share identical electrical specifications, pinout, and package geometry, enabling drop-in replacement capability.
The primary distinction between these parts is product lifecycle status and regulatory compliance. The MAX4558ESE is obsolete, while the MAX4558ESE+ maintains active production status. Additionally, the MAX4558ESE+ achieves ROHS3 compliance, whereas the original MAX4558ESE is RoHS non-compliant.
For new designs and production applications, the MAX4558ESE+ is the appropriate selection due to its active availability and enhanced regulatory compliance posture. Existing designs using the MAX4558ESE can transition to the MAX4558ESE+ without circuit modification, as all electrical and mechanical parameters remain identical.
Frequently Asked Questions (FAQ)
Q: Can the MAX4558ESE+ replace the MAX4558ESE in existing designs?
A: Yes. The MAX4558ESE+ is a direct substitute with identical electrical specifications, on-state resistance, switching characteristics, and 16-SOIC package geometry. No circuit redesign is required.
Q: What is the primary reason to transition from MAX4558ESE to MAX4558ESE+?
A: The MAX4558ESE is classified as obsolete, creating supply chain risk. The MAX4558ESE+ is in active production and offers ROHS3 compliance, ensuring long-term availability and regulatory alignment.
Q: Are the pin configurations identical between these parts?
A: Yes. Both components use the 16-SOIC package with identical pinout and electrical function. PCB layout and schematic connections require no modification.
