P2353UARP Equivalent & Substitute Parts

Part Overview

The P2353UARP is a 200V off-state, 150A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling in a compact 6-SMD, Gull Wing surface mount package. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2353UARP is determined by electrical and mechanical parameter equivalence. The critical parameters for substitution are:

• Voltage ratings (off-state, breakover, and on-state)
• Peak pulse current handling (both 8/20µs and 10/1000µs waveforms)
• Hold current specification
• Package configuration (6-SMD, Gull Wing)
• Number of internal elements (3)
• Capacitance values

The P2353UALRP meets all these criteria with identical electrical specifications and package geometry, differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P2353UALRP is a direct electrical and mechanical equivalent to the P2353UARP. Both components share identical voltage ratings, current specifications, element count, and package geometry. The primary differences are packaging format and product lifecycle status.

The P2353UALRP is currently in active production status, whereas the P2353UARP is obsolete. For new designs or ongoing procurement, the P2353UALRP is the appropriate selection. The P2353UALRP also carries ROHS3 compliance certification, whereas the P2353UARP is non-compliant. The P2353UALRP is supplied in Tape & Reel packaging, which is standard for automated assembly operations.

Frequently Asked Questions (FAQ)

Q: Can P2353UALRP replace P2353UARP in existing applications?

A: Yes. The P2353UALRP is electrically and mechanically identical to the P2353UARP. All voltage ratings, current specifications, and package dimensions are equivalent. The primary difference is product status and packaging format.

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

A: The P2353UARP is supplied in bulk packaging and is obsolete. The P2353UALRP is supplied in Tape & Reel format and is in active production. Electrical and mechanical specifications are identical.

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel packaging is a delivery and handling format only. The component itself is identical. Tape & Reel packaging is standard for automated pick-and-place assembly.

Q: Are there RoHS compliance differences?

A: Yes. The P2353UALRP is ROHS3 compliant, while the P2353UARP is non-compliant. For applications requiring RoHS compliance, the P2353UALRP is the required selection.

Q: Can I use P2353UALRP in designs originally specified for P2353UARP?

A: Yes, without modification. All electrical parameters, thermal characteristics, and mechanical interfaces are identical. Design validation is not required.
