Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3384ECWN is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Channel configuration: 2/2 (two drivers, two receivers)
• Duplex mode: Full
• Data rate capability: 250kbps minimum
• Supply voltage range: 3V ~ 5.5V
• Package type: 18-SOIC with identical physical dimensions
• Receiver hysteresis: 500 mV
• Mounting type: Surface mount

The MAX3384ECWN+ meets all these criteria and is identified as a parametric equivalent. The primary distinction between the main part and its substitute is product status and compliance certification.

Engineering Selection Recommendations

The MAX3384ECWN+ is the direct substitute for the MAX3384ECWN. Both parts are electrically and mechanically identical across all functional parameters. Selection between these parts is determined by application requirements and regulatory compliance:

For new designs and systems requiring RoHS3 compliance, the MAX3384ECWN+ is the appropriate choice. This part carries active product status, ensuring continued availability and manufacturing support.

For legacy systems currently using the MAX3384ECWN, the MAX3384ECWN+ provides a direct replacement without design modification. The identical electrical specifications, package dimensions, and pin configuration enable pin-for-pin substitution.

The MAX3384ECWN+ is supplied in tube packaging, whereas the original part packaging specification was not provided. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MAX3384ECWN+ replace the MAX3384ECWN in existing designs?

A: Yes. The MAX3384ECWN+ is a parametric equivalent with identical electrical and mechanical specifications. Pin configuration, package dimensions, and functional performance are equivalent, enabling direct substitution without circuit modification.

Q: What is the primary difference between these parts?

A: The MAX3384ECWN is obsolete, while the MAX3384ECWN+ is active. The MAX3384ECWN+ also carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. All electrical and mechanical parameters remain identical.

Q: Are there any compatibility concerns with the 18-SOIC package?

A: No. Both parts use the identical 18-SOIC package with 0.295" width and 7.50mm dimensions. PCB footprints, assembly processes, and mechanical mounting are fully compatible.

Q: Does the MAX3384ECWN+ support the same data rate and supply voltage?

A: Yes. The MAX3384ECWN+ maintains the 250kbps data rate and 3V to 5.5V supply voltage range of the original part. Operating temperature range is also identical at 0°C to 70°C.

Q: What is the significance of the receiver hysteresis specification?

A: The 500 mV receiver hysteresis is a key parameter defining RS232 signal detection characteristics. Both parts maintain this specification, ensuring equivalent noise immunity and signal integrity in RS232 communication links.
