CR3602AC Equivalent & Substitute Parts

Part Overview

The CR3602AC is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a bidirectional 2-channel configuration in a TO-220 Modified package with a reverse standoff voltage of 160V and breakdown voltage minimum of 220V. The CR3602AC is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system design and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CR3602AC is determined by the following critical parameters:

• Package Compatibility: Both parts must use 3-SIP / TO-220 Modified through-hole packaging to ensure mechanical and electrical fit within existing PCB layouts
• Channel Configuration: Bidirectional 2-channel architecture must be maintained for symmetric overvoltage protection
• Voltage Ratings: Reverse standoff voltage and breakdown voltage specifications must align with circuit protection requirements
• Thermal Operating Range: Temperature range must support the intended application environment
• Regulatory Compliance: RoHS and REACH status must meet current procurement and environmental standards

The P3602ACL substitute part satisfies these substitution criteria through equivalent package geometry, matching channel count, compatible voltage specifications, and active product status with current compliance certifications.

Engineering Selection Recommendations

The P3602ACL is the manufacturer-recommended substitute for the obsolete CR3602AC. Selection of this substitute part is justified by the following factors:

• Product Status: The P3602ACL maintains active product status, ensuring continued availability and manufacturer support, whereas the CR3602AC is obsolete
• Regulatory Compliance: The P3602ACL achieves ROHS3 compliance and REACH unaffected status, meeting current environmental and procurement regulations
• Package Compatibility: Both parts utilize identical 3-SIP / TO-220 Modified through-hole packaging, enabling direct PCB layout compatibility
• Electrical Equivalence: The P3602ACL maintains the 2-channel bidirectional configuration with voltage ratings within the operational envelope of the CR3602AC
• Moisture Sensitivity: Both parts share MSL 1 (Unlimited) classification, indicating equivalent handling and storage requirements

Frequently Asked Questions (FAQ)

Q: Can the P3602ACL be used as a direct replacement for the CR3602AC in existing designs?

A: Yes. Both parts share identical 3-SIP / TO-220 Modified packaging, 2-channel bidirectional configuration, and compatible voltage specifications. No PCB layout modifications are required.

Q: What are the key differences between the CR3602AC and P3602ACL?

A: The primary differences are product status (obsolete vs. active), regulatory compliance (RoHS non-compliant vs. ROHS3 compliant), and device technology (Zener vs. SIDACtor® thyristor). Voltage and package specifications remain compatible.

Q: Are there any thermal or environmental considerations when substituting these parts?

A: Both parts share MSL 1 (Unlimited) moisture sensitivity classification. Operating temperature data for the P3602ACL is not provided in the manufacturer specifications; verify thermal requirements against your specific application environment.

Q: Does the P3602ACL require any circuit modifications?

A: No circuit modifications are required. The substitute part maintains electrical compatibility through equivalent package geometry, channel count, and voltage specifications.

Q: What is the inventory status for these parts?

A: The CR3602AC has 728 pieces in stock (obsolete status). The P3602ACL has 888 pieces in stock with active product status.
