Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0602AA is determined by electrical and mechanical parameter equivalence within the SIDACtor® TVS thyristor product family. The following parameters establish substitution validity:

• Voltage ratings (Off-State: 25V, 50V; Breakover: 40V, 80V)
• Peak pulse current capability (150A at 8/20µs; 45A at 10/1000µs)
• Hold current specification (50mA minimum)
• Capacitance characteristics (90pF, 145pF)
• Package configuration (3-SIP, TO-220 Modified)
• Dual-element architecture (2 elements)
• Through-hole mounting compatibility

Parts meeting all these electrical and mechanical criteria are classified as direct substitutes and may be used interchangeably in circuit applications designed for the P0602AA.

Parameter Comparison

Engineering Selection Recommendations

The P0602AAL is the direct substitute for the obsolete P0602AA. 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 P0602AA is classified as Obsolete with RoHS non-compliant status. The P0602AAL maintains Active product status and achieves ROHS3 compliance, making it the preferred selection for new designs and ongoing production requiring regulatory adherence.

For applications where the P0602AA is currently deployed, transition to the P0602AAL is supported by complete electrical and mechanical compatibility. No circuit redesign or board layout modification is required.

Frequently Asked Questions (FAQ)

Q: Can the P0602AAL directly replace the P0602AA in existing circuits?

A: Yes. The P0602AAL provides identical electrical performance and mechanical compatibility. Both components feature the same voltage ratings, current specifications, capacitance values, and 3-SIP TO-220 Modified package configuration. Direct substitution is supported without circuit modification.

Q: What is the primary reason to transition from P0602AA to P0602AAL?

A: The P0602AA is Obsolete with limited availability. The P0602AAL is an Active product with established supply chain support. Additionally, the P0602AAL achieves ROHS3 compliance, addressing regulatory requirements for new production and markets with RoHS mandates.

Q: Are there any packaging or mounting differences between these parts?

A: No. Both the P0602AA and P0602AAL use identical 3-SIP package configuration with TO-220 Modified supplier device packaging. Through-hole mounting compatibility is maintained across both components.

Q: What electrical parameters determine substitution validity for this TVS thyristor?

A: Substitution is valid when the following parameters match: Off-State voltage (25V, 50V), Breakover voltage (40V, 80V), On-State voltage (4V), Peak pulse current (150A at 8/20µs; 45A at 10/1000µs), Hold current (50mA), element count (2), and capacitance values (90pF, 145pF).

Q: Is the P0602AAL suitable for applications requiring RoHS compliance?

A: Yes. The P0602AAL is ROHS3 compliant and REACH unaffected, meeting regulatory requirements for RoHS-mandated markets and applications.
