P3203UBRP Equivalent & Substitute Parts

Part Overview

The P3203UBRP is a 270V 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 functionally equivalent active alternatives is essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P3203UBRP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current specifications (both 8/20µs and 10/1000µs ratings)
• Hold current (Ih)
• Number of internal elements
• Capacitance range
• Physical package and mounting configuration

The P3203UBLRP qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction between these parts is packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The P3203UBLRP is the direct functional equivalent for the obsolete P3203UBRP. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and performance compatibility.

Key selection factors:

• The P3203UBLRP maintains active product status, ensuring long-term availability and supply chain reliability.
• The P3203UBLRP carries ROHS3 compliance, whereas the P3203UBRP is non-compliant. For applications subject to RoHS regulations, the P3203UBLRP is the required choice.
• Both components feature MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
• Packaging differs only in format: P3203UBRP is supplied in bulk, while P3203UBLRP is supplied in tape and reel format. This distinction affects procurement and assembly processes but does not impact electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the P3203UBLRP directly replace the P3203UBRP in existing designs?

A: Yes. The P3203UBLRP is electrically and mechanically identical to the P3203UBRP. No circuit modifications or design changes are required for substitution.

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

A: Bulk packaging (P3203UBRP) supplies components in loose form, suitable for manual handling or small-volume applications. Tape & reel packaging (P3203UBLRP) is formatted for automated pick-and-place assembly equipment, standard in high-volume manufacturing. Both formats contain identical components with no performance differences.

Q: Why is RoHS compliance important for this substitution?

A: RoHS regulations restrict hazardous substances in electrical and electronic equipment. The P3203UBLRP's ROHS3 compliance ensures it meets current environmental and regulatory standards. For applications in regulated markets or industries with RoHS requirements, the P3203UBLRP is the appropriate selection.

Q: Are there any electrical performance differences between these parts?

A: No. Both the P3203UBRP and P3203UBLRP share identical voltage ratings, current specifications, hold current, capacitance values, and number of internal elements. Performance in transient voltage suppression applications is equivalent.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: MSL 1 indicates the component has no moisture sensitivity. It requires no special dry-pack storage, desiccant handling, or bake-out procedures prior to assembly. Standard storage conditions are acceptable.
