MAX366CSA Equivalent & Substitute Parts

Part Overview

The MAX366CSA is a Transient Voltage Suppressor (TVS) device manufactured by Analog Devices Inc./Maxim Integrated, designed for circuit protection applications. This mixed-technology TVS device provides transient voltage suppression across three independent circuits with a clamping voltage of ±40V. The MAX366CSA is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX366CSA is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: ±40V (exact match required)
• Number of Circuits: 3 (exact match required)
• Technology: Mixed Technology (exact match required)
• Package / Case: 8-SOIC (0.154", 3.90mm Width) (exact match required)
• Mounting Type: Surface Mount (exact match required)

The MAX366CSA+ meets all substitution criteria as a direct equivalent part. Both devices share identical electrical specifications and physical packaging, ensuring pin-for-pin compatibility and functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The MAX366CSA+ is the direct substitute for the MAX366CSA. Both parts are electrically and mechanically identical, with identical pin configurations and functional performance in circuit protection applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The MAX366CSA is obsolete and RoHS non-compliant, while the MAX366CSA+ is an active product with ROHS3 compliance. For new designs and ongoing procurement, the MAX366CSA+ is the appropriate selection. Both parts maintain identical moisture sensitivity levels and REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can MAX366CSA+ be used as a direct replacement for MAX366CSA?

A: Yes. The MAX366CSA+ is a direct pin-for-pin equivalent with identical electrical specifications (±40V clamping voltage, 3 circuits, mixed technology) and physical packaging (8-SOIC). No circuit modifications are required.

Q: What is the primary reason to transition from MAX366CSA to MAX366CSA+?

A: The MAX366CSA is obsolete. The MAX366CSA+ is an active product offering continued manufacturer support, availability, and ROHS3 regulatory compliance.

Q: Are there any differences in moisture sensitivity or handling requirements?

A: No. Both parts share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), requiring no changes to storage or handling procedures.

Q: Is the 8-SOIC package identical between both parts?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with surface mount mounting type, ensuring identical PCB footprints and assembly compatibility.
