P3602AA Equivalent & Substitute Parts

Part Overview

The P3602AA is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. under the SIDACtor® series. This component is designed for overvoltage protection applications requiring 170V/340V off-state voltage rating with 150A peak pulse current capability in a 3-SIP through-hole package. The P3602AA is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The P3602AA has one direct functional equivalent: P3602AALRP. This substitution is valid based on identical electrical and mechanical parameters:

• Voltage ratings (breakover, off-state, and on-state) are identical
• Peak pulse current specifications (8/20µs and 10/1000µs) match exactly
• Hold current (Ih) is identical at 150 mA
• Number of elements, capacitance values, and mounting configuration are unchanged
• Package type (3-SIP, TO-220 Modified) and through-hole mounting are preserved

The primary distinction between these parts is packaging format and product status. The P3602AALRP is supplied in Tape & Reel format and maintains Active product status, whereas the P3602AA is obsolete.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing system support, the P3602AALRP is the appropriate selection. This part maintains identical electrical and mechanical specifications to the obsolete P3602AA while offering the following advantages:

• Active product status ensures long-term availability and manufacturing continuity
• ROHS3 compliance satisfies current environmental and regulatory requirements
• Tape & Reel packaging supports automated assembly processes and inventory management
• Identical performance characteristics guarantee direct functional replacement without circuit redesign

The P3602AA should be reserved for legacy system maintenance only where existing inventory is available and regulatory compliance is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can P3602AALRP be used as a direct replacement for P3602AA in existing designs?

A: Yes. The P3602AALRP provides identical electrical performance across all specified parameters including voltage ratings, peak pulse current, hold current, and capacitance values. The 3-SIP package and TO-220 Modified footprint are unchanged, enabling direct PCB compatibility.

Q: What is the difference between P3602AA and P3602AALRP?

A: The primary differences are product status, RoHS compliance, and packaging format. The P3602AA is obsolete and RoHS non-compliant, supplied in bulk packaging. The P3602AALRP is an active product with ROHS3 compliance, supplied in Tape & Reel format for automated assembly.

Q: Does the Tape & Reel packaging of P3602AALRP affect electrical performance?

A: No. Packaging format does not alter electrical characteristics. The Tape & Reel format is a supply and handling specification that improves manufacturing efficiency and inventory control without affecting component performance.

Q: Are there any circuit modifications required when switching from P3602AA to P3602AALRP?

A: No circuit modifications are required. All electrical parameters, mechanical dimensions, and pin configurations are identical. The substitution is a direct replacement at the component level.

Q: What is the significance of ROHS3 compliance on P3602AALRP?

A: ROHS3 compliance indicates the component meets current European Union Restriction of Hazardous Substances regulations. This certification is required for products sold in regulated markets and is a standard requirement for new component procurement.
