Substitute Part Grouping Explanation

Substitution eligibility for the MAX367CWN is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: ±40V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 8 (exact match required)
• Package / Case: 18-SOIC (0.295", 7.50mm Width) (exact match required)
• Mounting Type: Surface Mount (exact match required)

The MAX367CWN+ qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between these parts is product status and compliance certification, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The MAX367CWN+ is the direct functional equivalent of the MAX367CWN. Selection between these parts should be based on the following factors:

For new designs and procurement: The MAX367CWN+ is the appropriate choice due to its active product status and ROHS3 compliance certification. This part meets current regulatory requirements and benefits from ongoing manufacturer support.

For legacy system maintenance: The MAX367CWN remains functionally equivalent for applications where RoHS compliance is not a requirement. However, availability is limited to existing inventory (2336 pcs), and the obsolete status indicates no future production.

Both parts share identical electrical performance characteristics, mechanical compatibility, and environmental ratings. The choice between them depends on compliance requirements and long-term component availability strategy rather than technical performance.

Frequently Asked Questions (FAQ)

Q: Can MAX367CWN+ be used as a direct replacement for MAX367CWN in existing designs?

A: Yes. The MAX367CWN+ is electrically and mechanically identical to the MAX367CWN. Both devices feature ±40V clamping voltage, 8 circuits, mixed technology, and identical 18-SOIC packaging. No circuit modifications are required for substitution.

Q: What is the primary difference between MAX367CWN and MAX367CWN+?

A: The primary differences are product status and compliance certification. The MAX367CWN is obsolete and RoHS non-compliant, while the MAX367CWN+ is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 18-SOIC (0.295", 7.50mm Width) package with the same pinout configuration. PCB layout and footprint compatibility is complete.

Q: Why should I choose MAX367CWN+ over MAX367CWN for new designs?

A: The MAX367CWN+ offers active product status with ongoing manufacturer support and ROHS3 compliance certification. The MAX367CWN is obsolete with limited remaining inventory. For designs requiring regulatory compliance or long-term component availability, MAX367CWN+ is the appropriate selection.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating identical handling and storage requirements.
