P3206UBRP Equivalent & Substitute Parts

Part Overview

The P3206UBRP is a 270V off-state transient voltage suppressor (TVS) thyristor manufactured by Littelfuse Inc. as part of the SIDACtor® series. This component is designed for surface mount applications in 6-SMD gull wing packaging and provides peak pulse current handling of 250 A at 8/20µs pulse width. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3206UBRP is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current specifications (both 8/20µs and 10/1000µs)
• Hold current (Ih)
• Number of elements (6-element configuration)
• Capacitance values
• Physical package format (6-SMD, gull wing)
• Mounting type (surface mount)

The P3206UBLRP meets all these criteria with identical electrical specifications and package configuration. The primary distinction between these parts is packaging format (bulk versus tape & reel) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The P3206UBLRP is a direct functional equivalent to the P3206UBRP with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: The P3206UBRP is obsolete, while the P3206UBLRP is active. For new designs or ongoing production requiring long-term component availability, the P3206UBLRP is the appropriate selection.

Compliance Requirements: The P3206UBLRP carries ROHS3 compliance certification, whereas the P3206UBRP is non-compliant. Applications subject to RoHS regulations require the P3206UBLRP.

Packaging Format: The P3206UBRP is supplied in bulk packaging, while the P3206UBLRP is supplied in tape & reel format. Packaging selection depends on production volume and assembly line requirements.

REACH Status: The P3206UBLRP is designated as REACH Unaffected, providing regulatory clarity for applications in REACH-regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the P3206UBLRP replace the P3206UBRP in existing designs?

A: Yes. The P3206UBLRP is electrically and mechanically identical to the P3206UBRP. All voltage ratings, current specifications, capacitance values, and package dimensions are equivalent. Direct substitution is possible without circuit modification.

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

A: Bulk packaging (P3206UBRP) is suitable for manual assembly or small-volume applications. Tape & reel packaging (P3206UBLRP) is designed for automated pick-and-place assembly equipment and high-volume production. The components themselves are identical.

Q: Why is the P3206UBRP listed as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of a product line. The P3206UBLRP represents the active equivalent in the SIDACtor® series and should be used for new designs and ongoing procurement.

Q: Are there compliance differences between these parts?

A: Yes. The P3206UBLRP is ROHS3 compliant and REACH Unaffected, while the P3206UBRP is RoHS non-compliant. Applications requiring regulatory compliance must use the P3206UBLRP.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the P3206UBRP and P3206UBLRP have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
