P0602AC Equivalent & Substitute Parts

Part Overview

The P0602AC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in electronic circuits. This component features a 25V/50V off-state voltage rating with 400A peak pulse current capability in a 3-SIP through-hole package. The P0602AC is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0602AC is determined by electrical and mechanical parameter equivalence within the SIDACtor® TVS thyristor family. The following parameters establish substitution validity:

• Voltage ratings (breakover and off-state) must match exactly: 40V/80V breakover and 25V/50V off-state
• Peak pulse current capability must equal or exceed 400A (8/20µs) and 100A (10/1000µs)
• On-state voltage must remain at 4V
• Hold current (Ih) must be 50 mA
• Number of elements must be 2
• Capacitance range must fall within 145pF to 250pF
• Package configuration must be 3-SIP with TO-220 Modified supplier device package
• Through-hole mounting type is required

The P0602ACL meets all these criteria and is classified as a direct manufacturer substitute.

Parameter Comparison

Engineering Selection Recommendations

The P0602ACL is the direct substitute for the obsolete P0602AC. Both components share identical electrical specifications and mechanical packaging, ensuring functional equivalence in circuit applications.

The primary distinction between these parts is product status and regulatory compliance. The P0602AC is obsolete and RoHS non-compliant, while the P0602ACL is active and ROHS3 compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the P0602ACL is the appropriate selection. For legacy system maintenance where the original part specification must be preserved, the P0602ACL provides electrical and mechanical compatibility while offering improved compliance status.

Frequently Asked Questions (FAQ)

Q: Can the P0602ACL be used as a direct replacement for the P0602AC?

A: Yes. The P0602ACL is electrically and mechanically identical to the P0602AC. All voltage ratings, current specifications, and package dimensions are equivalent. The components are pin-compatible and functionally interchangeable in circuit applications.

Q: What is the difference between the P0602AC and P0602ACL?

A: The primary differences are product status and regulatory compliance. The P0602AC is obsolete and RoHS non-compliant. The P0602ACL is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: No. Both the P0602AC and P0602ACL use the same 3-SIP package with TO-220 Modified supplier device package configuration. Through-hole mounting is identical for both components.

Q: What are the key electrical parameters that define substitution for this TVS thyristor?

A: Substitution is determined by matching voltage ratings (40V/80V breakover, 25V/50V off-state), peak pulse current (400A at 8/20µs, 100A at 10/1000µs), on-state voltage (4V), hold current (50 mA), element count (2), and capacitance range (145pF to 250pF).

Q: Is the P0602ACL suitable for new designs?

A: Yes. The P0602ACL is an active product with ROHS3 compliance, making it appropriate for new design implementations. It provides the same electrical performance as the obsolete P0602AC with improved regulatory compliance.
