MAX367EWN Equivalent & Substitute Parts

Part Overview

The MAX367EWN is a Transient Voltage Suppressors (TVS) device manufactured by Analog Devices Inc./Maxim Integrated, designed for circuit protection applications. This 8-circuit mixed technology TVS device operates at ±40V clamping voltage and is housed in an 18-SOIC surface mount package. The MAX367EWN is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement planning. The primary driver for substitution is the discontinued product status, which necessitates sourcing from active product lines that maintain equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX367EWN is determined by strict adherence to the following parameters:

• Voltage - Clamping: Must match ±40V specification
• Number of Circuits: Must provide 8 circuits
• Package / Case: Must be 18-SOIC (0.295", 7.50mm Width) for PCB compatibility
• Mounting Type: Must be Surface Mount
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The MAX367EWN+ qualifies as a direct substitute based on these criteria. Both devices share identical clamping voltage, circuit count, package configuration, and mounting specifications. The primary distinction is the technology implementation (Mixed Technology versus MOSFET Array) and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The MAX367EWN+ is the appropriate substitute for the obsolete MAX367EWN. Both devices maintain identical electrical specifications (40V clamping voltage, 8 circuits) and mechanical compatibility (18-SOIC package, surface mount configuration). The MAX367EWN+ offers the additional advantage of active product status, ensuring continued availability and manufacturing support. The MAX367EWN+ achieves ROHS3 compliance, whereas the original MAX367EWN is non-compliant; this distinction should be evaluated against your design and regulatory requirements. Both devices carry REACH Unaffected status and share equivalent moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can the MAX367EWN+ be used as a direct replacement for the MAX367EWN?

A: Yes. Both devices share identical clamping voltage (40V), circuit count (8), package configuration (18-SOIC), and mounting type (surface mount). The devices are pin-compatible and functionally equivalent for general purpose TVS applications.

Q: What is the primary difference between MAX367EWN and MAX367EWN+?

A: The MAX367EWN uses mixed technology, while the MAX367EWN+ employs MOSFET array technology. The MAX367EWN+ is an active product with ROHS3 compliance, whereas the MAX367EWN is obsolete and RoHS non-compliant.

Q: Are there any package or pinout differences?

A: No. Both devices use the 18-SOIC (0.295", 7.50mm Width) package with identical pinout and surface mount configuration. PCB layouts require no modification for substitution.

Q: What is the moisture sensitivity level for both devices?

A: Both the MAX367EWN and MAX367EWN+ carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Should RoHS compliance be a factor in selecting between these devices?

A: RoHS compliance requirements depend on your application and regulatory jurisdiction. The MAX367EWN+ meets ROHS3 standards, while the MAX367EWN does not. Evaluate your design requirements accordingly.
