Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX230EWP is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Driver/Receiver configuration: 5/0
• Data rate capability: 250kbps minimum
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package type: 20-SOIC form factor
• Mounting technology: Surface Mount

The MAX230EWP+ qualifies as a direct substitute based on identical electrical specifications, mechanical compatibility, and functional equivalence across all listed parameters. The primary distinction between these parts is product status and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The MAX230EWP+ is the appropriate substitute for the obsolete MAX230EWP. Both components share identical electrical and mechanical specifications, ensuring direct functional compatibility in existing circuit designs. The MAX230EWP+ maintains active product status with current manufacturing support from Analog Devices Inc./Maxim Integrated.

The MAX230EWP+ achieves ROHS3 compliance, whereas the original MAX230EWP does not meet RoHS requirements. This distinction is significant for applications subject to regulatory compliance mandates. Both parts maintain equivalent moisture sensitivity classification and REACH status.

Selection between these parts should be based on regulatory requirements and supply chain availability. The MAX230EWP+ is the preferred choice for new designs and systems requiring RoHS compliance. The MAX230EWP remains functionally equivalent for applications without RoHS constraints, subject to inventory availability.
