P3602AC Equivalent & Substitute Parts

Part Overview

The P3602AC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. under the SIDACtor® series. This component is designed for overvoltage protection applications requiring high peak pulse current handling. The P3602AC operates with 170V/340V off-state voltage ratings and supports 400A peak pulse current at 8/20µs pulse width. Due to its obsolete product status, identifying compatible substitute parts is essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P3602AC is determined by strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Voltage - Breakover: 220V, 440V
• Voltage - Off State: 170V, 340V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Number of Elements: 2
• Package / Case: 3-SIP (TO-220 Modified)
• Mounting Type: Through Hole

The P3602ACL meets all electrical specifications and mechanical requirements, maintaining identical performance characteristics while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P3602ACL is the direct substitute for the P3602AC. Both components share identical electrical performance specifications and mechanical form factors. The P3602ACL offers two significant advantages:

Product Status: The P3602ACL maintains Active product status, ensuring continued availability and manufacturer support, whereas the P3602AC is Obsolete.

Regulatory Compliance: The P3602ACL is ROHS3 Compliant, meeting current environmental and regulatory requirements. The P3602AC is RoHS non-compliant, which may present procurement and deployment restrictions in regulated markets.

For new designs and system replacements, the P3602ACL is the appropriate selection. For legacy system maintenance requiring exact part matching, the P3602AC remains functionally equivalent where available inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the P3602ACL be used as a direct replacement for the P3602AC?

A: Yes. The P3602ACL is electrically and mechanically identical to the P3602AC. All voltage ratings, current specifications, and package dimensions match exactly. The components are pin-compatible and functionally interchangeable.

Q: What is the difference between P3602AC and P3602ACL?

A: The primary differences are product status and regulatory compliance. The P3602ACL is an Active product with ROHS3 compliance, while the P3602AC is Obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: The P3602AC is supplied in standard packaging, while the P3602ACL is supplied in Bulk packaging. Both use the 3-SIP (TO-220 Modified) case and Through Hole mounting type. Packaging format does not affect electrical performance or mechanical compatibility.

Q: Why is the P3602AC marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. The P3602ACL represents the current active equivalent, ensuring access to ongoing supply and technical support.

Q: Is the P3602ACL suitable for new designs?

A: Yes. The P3602ACL is the recommended choice for new designs. Its Active product status and ROHS3 compliance ensure regulatory alignment and long-term availability.
