P2353UBRP Equivalent & Substitute Parts

Part Overview

The P2353UBRP is a 200V off-state TVS thyristor from Littelfuse Inc.'s SIDACtor® series, designed for transient voltage suppression applications. This component features a 6-SMD gull wing package with a peak pulse current rating of 250 A (8/20µs) and is currently classified as obsolete. Due to its discontinued status, identifying compatible substitute parts is essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2353UBRP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (off-state, breakover, and on-state)
• Peak pulse current specifications (both 8/20µs and 10/1000µs ratings)
• Hold current (Ih)
• Number of internal elements
• Capacitance range
• Package configuration (6-SMD, gull wing)
• Surface mount compatibility

The P2353UBLRP qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction between these parts is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P2353UBLRP is the direct functional equivalent of the P2353UBRP. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility in circuit applications.

Selection between these parts should be based on the following factors:

Product Status: The P2353UBRP is obsolete, while the P2353UBLRP maintains active production status. For new designs or long-term system support, the P2353UBLRP is the appropriate choice.

Regulatory Compliance: The P2353UBLRP is ROHS3 compliant, whereas the P2353UBRP is non-compliant. Applications subject to RoHS regulations require the P2353UBLRP.

Packaging Format: The P2353UBRP is supplied in bulk packaging, while the P2353UBLRP is supplied in tape and reel format. Packaging selection depends on manufacturing volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Can the P2353UBLRP directly replace the P2353UBRP in existing designs?

A: Yes. The P2353UBLRP is electrically and mechanically identical to the P2353UBRP. Both components feature the same voltage ratings, current specifications, element count, and 6-SMD gull wing package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between the P2353UBRP and P2353UBLRP?

A: The primary differences are product status, RoHS compliance, and packaging format. The P2353UBRP is obsolete and non-compliant with RoHS3, supplied in bulk. The P2353UBLRP is active, ROHS3 compliant, and supplied in tape and reel format. Electrical and mechanical specifications are identical.

Q: Which part should be selected for new product designs?

A: The P2353UBLRP should be selected for new designs. It maintains active production status and meets current regulatory requirements including ROHS3 compliance.

Q: Are there packaging compatibility considerations when switching from P2353UBRP to P2353UBLRP?

A: Both parts use identical 6-SMD gull wing surface mount packages. The difference is in supply format: bulk versus tape and reel. Assembly equipment compatibility depends on your manufacturing process, not on the components themselves.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching voltage ratings (200V off-state, 270V breakover, 8V on-state), peak pulse current (250A at 8/20µs, 80A at 10/1000µs), hold current (150mA), element count (3), and capacitance range (50pF, 75pF).
