Substitute Part Grouping Explanation

Substitution eligibility for the P0602AB is determined by strict equivalence across the following critical parameters:

• Voltage ratings (Breakover: 40V/80V; Off-State: 25V/50V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 250A; Peak Pulse 10/1000µs: 80A; Hold Current: 50mA)
• Element configuration (2 elements)
• Capacitance values (145pF, 250pF)
• Package type (3-SIP, TO-220 Modified)
• Mounting method (Through Hole)

The P0602ABL qualifies as a direct substitute based on identical electrical and mechanical specifications across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The P0602ABL is the direct equivalent substitute for the obsolete P0602AB. Both components share identical electrical performance characteristics and mechanical specifications. The primary distinction is product status and regulatory compliance: the P0602ABL maintains active production status and meets ROHS3 compliance requirements, whereas the P0602AB is obsolete and non-compliant with current RoHS standards. For new designs and ongoing system support, the P0602ABL is the appropriate selection. Both components maintain equivalent moisture sensitivity classification (MSL 1) and are suitable for through-hole mounting applications requiring 250A peak pulse current handling in dual-element TVS thyristor configurations.

Frequently Asked Questions (FAQ)

Q: Can the P0602ABL be used as a direct replacement for the P0602AB in existing designs?

A: Yes. The P0602ABL provides identical electrical and mechanical performance. All voltage ratings, current specifications, element configuration, capacitance values, and package dimensions match the P0602AB exactly. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference between P0602AB and P0602ABL?

A: The P0602AB is classified as obsolete, indicating discontinued manufacturing and limited availability. The P0602ABL is active production, ensuring long-term supply chain reliability and continued manufacturer support. For new designs and long-term system maintenance, the active P0602ABL is the recommended choice.

Q: How does RoHS compliance affect component selection?

A: The P0602AB is RoHS non-compliant, while the P0602ABL meets ROHS3 standards. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the P0602ABL is the required selection. Both components maintain identical functional performance.

Q: Are there any package or mounting differences between these components?

A: No. Both the P0602AB and P0602ABL use identical 3-SIP package configuration with TO-220 Modified supplier device package designation. Through-hole mounting specifications are equivalent, allowing direct PCB layout compatibility.

Q: What electrical parameters define substitution eligibility for this TVS thyristor?

A: Substitution requires matching across all specified parameters: breakover voltage (40V/80V), off-state voltage (25V/50V), on-state voltage (4V), peak pulse current ratings (250A at 8/20µs; 80A at 10/1000µs), hold current (50mA), element count (2), and capacitance values (145pF/250pF). The P0602ABL meets all these criteria.
