P3602AARP Equivalent & Substitute Parts

Part Overview

The P3602AARP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. as part of the SIDACtor® series. This component is designed for overvoltage protection applications, featuring a 170V/340V off-state voltage rating with 150A peak pulse current capability in a 3-SIP through-hole package. The P3602AARP is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3602AARP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings (breakover and off-state) must match exactly: 220V/440V breakover and 170V/340V off-state
• Peak pulse current capability must be identical: 150A at 8/20µs pulse width
• On-state voltage must remain at 4V
• Hold current specification must be 150 mA
• Package configuration must be 3-SIP in TO-220 Modified form factor
• Mounting type must be through-hole

The P3602AALRP satisfies all these criteria and is therefore a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The P3602AALRP is the direct equivalent for P3602AARP replacement. Both components share identical electrical specifications and mechanical form factors. The primary distinction is product status and regulatory compliance: P3602AALRP is actively manufactured and ROHS3 compliant, whereas P3602AARP is obsolete and RoHS non-compliant. For new designs or system updates, P3602AALRP is the appropriate selection. For legacy system maintenance where RoHS compliance is not a constraint, P3602AARP inventory may be utilized if available, though P3602AALRP is preferred for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can P3602AALRP be used as a direct replacement for P3602AARP?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including voltage ratings, current ratings, on-state voltage, hold current, capacitance, and package configuration.

Q: What is the difference between P3602AARP and P3602AALRP?

A: The components are functionally equivalent. The primary differences are packaging format (P3602AARP is bulk; P3602AALRP is tape and reel), product status (P3602AARP is obsolete; P3602AALRP is active), and RoHS compliance (P3602AARP is non-compliant; P3602AALRP is ROHS3 compliant).

Q: Are there any circuit design modifications required when substituting P3602AALRP for P3602AARP?

A: No. The electrical and mechanical specifications are identical, so no circuit modifications are necessary. Direct board-level substitution is supported.

Q: What packaging options are available for these components?

A: P3602AARP is supplied in bulk packaging. P3602AALRP is supplied in tape and reel format. Both use the 3-SIP TO-220 Modified through-hole package for PCB mounting.

Q: Is P3602AALRP suitable for new product designs?

A: Yes. P3602AALRP is actively manufactured and ROHS3 compliant, making it the appropriate choice for new designs and systems requiring regulatory compliance.
