P3203UBTP Equivalent & Substitute Parts

Part Overview

The P3203UBTP is a 270V off-state TVS thyristor from Littelfuse'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 P3203UBTP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings: Breakover voltage (350V), off-state voltage (270V), and on-state voltage (8V)
• Current specifications: Peak pulse current (8/20µs at 250A and 10/1000µs at 80A) and hold current (150mA)
• Element configuration: 3-element design
• Capacitance characteristics: 45pF and 70pF ratings
• Physical form factor: 6-SMD gull wing package in Modified MS-013 supplier package

The P3203UBLTP meets all these criteria and qualifies as a direct functional equivalent. The primary distinction between these parts is product status and packaging format, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The P3203UBLTP is the direct substitute for the obsolete P3203UBTP. Both parts are electrically and mechanically identical across all specified parameters. The P3203UBLTP carries active product status, ensuring long-term availability and supply chain reliability.

The P3203UBLTP provides an additional compliance advantage: it meets ROHS3 standards, whereas the P3203UBTP is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the P3203UBLTP is the appropriate selection. Both parts maintain identical MSL ratings and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the P3203UBLTP be used as a direct replacement for the P3203UBTP?

A: Yes. The P3203UBLTP is electrically and mechanically equivalent to the P3203UBTP across all specified parameters, including voltage ratings, current specifications, element configuration, capacitance values, and package form factor.

Q: What is the primary difference between these two parts?

A: The P3203UBTP is obsolete, while the P3203UBLTP is active. Additionally, the P3203UBLTP is ROHS3 compliant, whereas the P3203UBTP is RoHS non-compliant.

Q: Are the packaging formats identical?

A: Yes. Both parts use a 6-SMD gull wing package in the Modified MS-013 supplier package configuration.

Q: Does the P3203UBLTP meet the same electrical specifications?

A: Yes. The P3203UBLTP maintains identical breakover voltage (350V), off-state voltage (270V), on-state voltage (8V), peak pulse current ratings (250A at 8/20µs and 80A at 10/1000µs), hold current (150mA), element count (3), and capacitance values (45pF, 70pF).

Q: Are there inventory considerations when selecting between these parts?

A: The P3203UBTP has 905 pieces in stock, while the P3203UBLTP has 894 pieces in stock. However, given the obsolete status of the P3203UBTP, the P3203UBLTP is the recommended selection for new designs and ongoing procurement.
