P3002AARP Equivalent & Substitute Parts

Part Overview

The P3002AARP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse, designed for overvoltage protection in 140V/280V off-state applications with 150A peak pulse current capability. This component is classified as obsolete, making identification of compatible alternatives essential for ongoing system support and new design implementations. The P3002AALRP serves as the direct functional equivalent with improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The P3002AALRP qualifies as a direct substitute for the P3002AARP based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Voltage ratings match exactly: 140V/280V off-state and 180V/360V breakover
• Current specifications are identical: 150A peak pulse (8/20µs) and 45A peak pulse (10/1000µs)
• On-state voltage remains constant at 4V
• Hold current specification is maintained at 150 mA
• Package configuration is identical: 3-SIP through-hole mounting
• Number of internal elements is the same: 2 elements
• Capacitance range is preserved: 25pF, 40pF

These parameters define the functional interchangeability of this TVS thyristor category.

Engineering Selection Recommendations

The P3002AALRP is the appropriate selection for new designs and system upgrades due to its active product status and ROHS3 compliance certification. The P3002AARP, while functionally equivalent in electrical and mechanical specifications, carries obsolete status and RoHS non-compliant classification, limiting its suitability for applications subject to environmental or regulatory requirements.

For existing systems currently using P3002AARP, direct replacement with P3002AALRP is electrically and mechanically valid. The identical electrical parameters ensure circuit performance remains unchanged. Packaging format differences (bulk versus tape & reel) do not affect component functionality and reflect only supply chain configuration.

Frequently Asked Questions (FAQ)

Q: Can P3002AALRP replace P3002AARP in existing circuits?

A: Yes. Both components share identical electrical specifications including voltage ratings (140V/280V off-state, 180V/360V breakover), current ratings (150A peak pulse at 8/20µs), and on-state voltage (4V). The 3-SIP through-hole package configuration is identical, enabling direct PCB substitution.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance certification. P3002AALRP is active production with ROHS3 compliance, while P3002AARP is obsolete and RoHS non-compliant. Electrical and mechanical performance are identical.

Q: Does packaging format affect compatibility?

A: No. P3002AARP is supplied in bulk packaging while P3002AALRP is supplied in tape & reel format. Both contain the same component with identical specifications. Packaging format reflects supply chain configuration only and does not impact circuit performance or PCB mounting.

Q: Are there any voltage or current derating considerations when substituting?

A: No. Both parts operate within identical voltage and current parameters. All electrical specifications including breakover voltage (180V/360V), off-state voltage (140V/280V), peak pulse current (150A at 8/20µs), and hold current (150 mA) are matched.

Q: What is the moisture sensitivity level for these components?

A: Both P3002AARP and P3002AALRP carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling.
