Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3388ECUG is determined by strict equivalence across the following critical parameters:

• Protocol and Configuration: RS232 full-duplex transceiver with 3 drivers and 2 receivers
• Electrical Performance: 460 Kbps data rate, 700 mV receiver hysteresis
• Supply Voltage Range: 3V to 5.5V operation
• Operating Temperature Range: 0°C to 70°C
• Package and Pinout: 24-TSSOP surface mount package with identical mechanical dimensions (0.173", 4.40mm Width)
• Functional Equivalence: Identical base product number (MAX3388E) with matching electrical and mechanical specifications

The MAX3388ECUG+ meets all these criteria and is therefore classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAX3388ECUG+ is the direct parametric equivalent substitute for the MAX3388ECUG. Both components share identical electrical specifications, pin configurations, and mechanical packaging, ensuring drop-in compatibility at the circuit board level.

The primary distinction between the two parts is product status and regulatory compliance. The MAX3388ECUG is obsolete, while the MAX3388ECUG+ maintains active production status. Additionally, the MAX3388ECUG+ achieves ROHS3 compliance, whereas the original MAX3388ECUG is RoHS non-compliant. Both parts are REACH Unaffected and classified under ECCN EAR99.

For new designs or applications requiring continued component availability, the MAX3388ECUG+ is the appropriate selection. For legacy systems currently using the MAX3388ECUG, the MAX3388ECUG+ provides a compliant, actively manufactured alternative without requiring circuit modifications.
