P2353AARP Equivalent & Substitute Parts

Part Overview

The P2353AARP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. under the SIDACtor® series. This component is designed for overvoltage protection applications, featuring a 200V off-state voltage rating and 150A peak pulse current capability in a 3-SIP through-hole package. The P2353AARP is classified as obsolete, making equivalent substitute parts necessary for ongoing system support and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P2353AARP are qualified based on identical electrical and mechanical parameters. The substitution criteria are:

• Voltage ratings: Breakover (270V), Off-State (200V), and On-State (8V) must match exactly
• Current specifications: Peak pulse current (8/20µs at 150A and 10/1000µs at 45A) and hold current (150mA) must be identical
• Physical form factor: 3-SIP package with through-hole mounting
• Number of elements: 3-element configuration
• Capacitance values: 25pF and 35pF

The P2353AAL and P2353AALRP meet all these criteria. The primary difference between substitutes is packaging format: P2353AAL is supplied in bulk packaging, while P2353AALRP is supplied in tape and reel format.

Parameter Comparison

Engineering Selection Recommendations

Both P2353AAL and P2353AALRP are direct functional equivalents to the obsolete P2353AARP, with identical electrical and mechanical specifications. The selection between these two substitutes depends on procurement and assembly requirements:

P2353AAL is appropriate for applications requiring bulk packaging and lower-volume procurement. This part is ROHS3 compliant and currently in active production status.

P2353AALRP is appropriate for automated assembly processes and higher-volume production runs, supplied in tape and reel format. This part is also ROHS3 compliant and in active production status.

Both substitute parts offer improved compliance status compared to the original P2353AARP, which is RoHS non-compliant. For new designs or system upgrades, either substitute provides equivalent performance with current regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can P2353AAL and P2353AALRP be used interchangeably with P2353AARP?

A: Yes. Both parts are electrically and mechanically identical to the P2353AARP. The only difference is packaging format: P2353AAL uses bulk packaging while P2353AALRP uses tape and reel packaging. Circuit performance and board-level compatibility are identical.

Q: What is the difference between bulk and tape & reel packaging?

A: Bulk packaging (P2353AAL) supplies components loose or in standard containers, suitable for manual assembly or lower-volume applications. Tape and reel packaging (P2353AALRP) supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both P2353AAL and P2353AALRP are ROHS3 compliant. The original P2353AARP is RoHS non-compliant. For applications requiring regulatory compliance, the substitute parts are the appropriate choice.

Q: Do the substitute parts have the same electrical performance as the original?

A: Yes. All three parts share identical voltage ratings (270V breakover, 200V off-state, 8V on-state), current specifications (150A peak pulse at 8/20µs, 45A at 10/1000µs, 150mA hold current), and capacitance values (25pF, 35pF).

Q: Which substitute should I select for my application?

A: Select P2353AAL for manual assembly or low-volume procurement. Select P2353AALRP for automated assembly lines or high-volume production. Both provide identical circuit-level performance.
