Substitute Part Grouping Explanation

Substitution of the MAX3185EAP is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 full-duplex transceiver functionality
• Driver/Receiver Configuration: 3 drivers and 5 receivers
• Electrical Performance: 230 kbps data rate, 650 mV receiver hysteresis, 4.5V to 5.5V supply voltage
• Operating Temperature Range: -40°C to 85°C
• Package Specification: 20-SSOP surface mount package with identical pinout and mechanical dimensions (0.209", 5.30mm Width)

The MAX3185EAP+ meets all these criteria as a parametric equivalent, maintaining identical electrical characteristics and mechanical compatibility while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX3185EAP+ is the direct parametric equivalent for the obsolete MAX3185EAP. Both components share identical electrical specifications, pin configurations, and mechanical package dimensions, ensuring drop-in compatibility in existing designs.

The MAX3185EAP+ offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the MAX3185EAP+ meets ROHS3 compliance requirements, whereas the original MAX3185EAP is RoHS non-compliant. For new designs or system redesigns, the MAX3185EAP+ is the appropriate selection. For legacy system maintenance requiring exact part matching, the MAX3185EAP+ provides functional and physical equivalence with improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the MAX3185EAP+ be used as a direct replacement for the MAX3185EAP?

A: Yes. The MAX3185EAP+ is a parametric equivalent with identical electrical performance, pin configuration, and 20-SSOP package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between MAX3185EAP and MAX3185EAP+?
