P3206UBTP Equivalent & Substitute Parts

Part Overview

The P3206UBTP 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 obsolete 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 P3206UBTP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current capabilities (both 8/20µs and 10/1000µs ratings)
• Hold current specification
• Element count and capacitance values
• Physical package configuration (6-SMD, gull wing)
• Mounting type (surface mount)

The P3206UBLTP qualifies as a direct substitute because it maintains identical electrical specifications and mechanical packaging while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P3206UBLTP is the direct equivalent for the obsolete P3206UBTP. Both components share identical electrical and mechanical specifications, ensuring functional interchangeability in circuit applications. The primary distinction is product lifecycle status: P3206UBLTP is active and carries ROHS3 compliance certification, whereas P3206UBTP is obsolete and RoHS non-compliant. For new designs or ongoing procurement, P3206UBLTP is the appropriate selection. Packaging differs only in format (tube versus unspecified for the original), which does not affect component performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can P3206UBLTP directly replace P3206UBTP in existing designs? A: Yes. Both components are electrically and mechanically identical across all specified parameters, including voltage ratings, current capabilities, element count, and package configuration.

Q: What is the difference between these two part numbers? A: The primary differences are product status (active versus obsolete) and compliance certifications. P3206UBLTP is ROHS3 compliant and currently in active production, while P3206UBTP is obsolete and RoHS non-compliant. Electrical performance and physical packaging are identical.

Q: Does the packaging format (tube) affect compatibility? A: No. Packaging format refers to how components are supplied for procurement and storage. The actual component package (6-SMD, gull wing) and mounting characteristics remain unchanged and are fully compatible with existing PCB designs.

Q: Are there any compliance considerations when switching to P3206UBLTP? A: P3206UBLTP offers improved compliance status with ROHS3 certification, which may be beneficial for regulatory requirements in certain markets or applications. This represents an advantage over the non-compliant P3206UBTP.

Q: What inventory status should I expect? A: P3206UBLTP has higher current inventory availability (998 pcs) compared to P3206UBTP (797 pcs), supporting more reliable procurement for ongoing production needs.
