P2202AARP Equivalent & Substitute Parts

Part Overview

The P2202AARP is a SIDACtor® TVS thyristor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. This device features 90V and 180V off-state voltage ratings with a 150A peak pulse current capability in a 3-SIP TO-220 Modified package. The P2202AARP is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2202AARP is determined by electrical and mechanical parameter equivalence. The primary substitute, P2202AALRP, maintains identical electrical specifications across all critical parameters: breakover voltage (130V, 260V), off-state voltage (90V, 180V), on-state voltage (4V), peak pulse current ratings (150A at 8/20µs and 45A at 10/1000µs), hold current (150mA), element count (2), capacitance values (30pF, 50pF), and mechanical form factor (3-SIP, TO-220 Modified, through-hole mounting).

The key differentiator between the main part and its substitute is product status and compliance certification. The P2202AARP is obsolete with non-compliant RoHS status, while the P2202AALRP is active with ROHS3 compliance and REACH unaffected status. Packaging format differs: P2202AARP is supplied in bulk form, while P2202AALRP is supplied in Tape & Reel format.

Parameter Comparison

Engineering Selection Recommendations

The P2202AALRP is the direct equivalent substitute for the obsolete P2202AARP. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications. The P2202AALRP is the preferred selection for new designs and ongoing procurement due to its active product status and ROHS3 compliance certification. The P2202AALRP maintains REACH unaffected status, meeting current regulatory requirements for electronic component procurement in regulated markets.

For applications currently using the P2202AARP, direct substitution with P2202AALRP is electrically and mechanically compatible. The primary consideration is packaging format: P2202AALRP is supplied in Tape & Reel format, which may require adjustment to procurement and assembly processes if the original design utilized bulk packaging.

Frequently Asked Questions (FAQ)

Q: Are the P2202AARP and P2202AALRP electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: 130V/260V breakover voltage, 90V/180V off-state voltage, 4V on-state voltage, 150A peak pulse current (8/20µs), 45A peak pulse current (10/1000µs), 150mA hold current, 2 elements, and 30pF/50pF capacitance values.

Q: What is the primary difference between these parts?

A: The P2202AARP is obsolete with RoHS non-compliant status, while the P2202AALRP is active with ROHS3 compliance. Packaging format also differs: P2202AARP is supplied in bulk form, while P2202AALRP is supplied in Tape & Reel format.

Q: Can I use P2202AALRP as a direct replacement in existing designs?

A: Yes. The P2202AALRP is mechanically and electrically compatible with the P2202AARP. Both use identical 3-SIP TO-220 Modified packages with through-hole mounting. Procurement and assembly processes may require adjustment due to Tape & Reel packaging format.

Q: Are there any compliance differences between these parts?

A: Yes. The P2202AALRP is ROHS3 compliant and REACH unaffected, while the P2202AARP is RoHS non-compliant. Both parts share the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

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

A: Both the P2202AARP and P2202AALRP have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.
