P3206UARP Equivalent & Substitute Parts

Part Overview

The P3206UARP is a 270V 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 obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P3206UARP is determined by strict equivalence across electrical and mechanical parameters. The critical parameters defining substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current specifications (both 8/20µs and 10/1000µs waveforms)
• Hold current (Ih)
• Element count and capacitance values
• Physical package configuration (6-SMD, gull wing)
• Supplier device package designation

Parts meeting all these criteria are classified as direct equivalents regardless of product status or compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P3206UALRP is a direct electrical and mechanical equivalent to the P3206UARP. Both parts share identical voltage ratings, current specifications, element configuration, and physical package dimensions. The primary distinctions are product lifecycle status and regulatory compliance.

The P3206UALRP carries active product status from Littelfuse Inc., ensuring continued availability and manufacturing support. This part also meets ROHS3 compliance requirements, whereas the P3206UARP is non-compliant. For applications requiring REACH compliance documentation, the P3206UALRP is designated as REACH Unaffected.

Packaging format differs between the two parts: P3206UARP is supplied in bulk configuration, while P3206UALRP is supplied in Tape & Reel format. This distinction affects handling, storage, and automated assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can P3206UALRP replace P3206UARP in existing designs?

A: Yes. The P3206UALRP is electrically and mechanically identical to the P3206UARP across all specified parameters including voltage ratings, current handling, element count, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging (P3206UARP) supplies components loose or in trays, suitable for manual assembly or small-volume applications. Tape & Reel packaging (P3206UALRP) supplies components on continuous carrier tape, optimized for automated pick-and-place assembly equipment. Electrical performance is identical; packaging selection depends on assembly process requirements.

Q: Why is P3206UARP marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The P3206UALRP remains in active production as the current equivalent offering from Littelfuse Inc.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical characteristics. Both parts deliver identical voltage suppression and current handling performance. RoHS3 compliance of the P3206UALRP may be required for applications subject to specific regulatory or procurement standards.

Q: Are there any thermal or reliability differences between these parts?

A: No differences are specified in the provided parameters. Both parts are manufactured by Littelfuse Inc. in the same SIDACtor® series with identical electrical ratings and package specifications.
