P1304UBTP Equivalent & Substitute Parts

Part Overview

The P1304UBTP is a SIDACtor® Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in 120V/240V applications. This component features a 6-SMD Gull Wing package with a peak pulse current rating of 250 A (8/20µs) and is classified as obsolete. Due to its obsolete status, identifying compatible substitute parts is essential for ongoing system maintenance and new design implementations where equivalent performance is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P1304UBTP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings (Breakover: 160V/320V; Off-State: 120V/240V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 250 A; Peak Pulse 10/1000µs: 80 A; Hold Current: 150 mA)
• Element count (4 elements)
• Capacitance range (60pF, 105pF)
• Package configuration (6-SMD, Gull Wing; Modified MS-013)
• Mounting type (Surface Mount)

The P1304UBLTP meets all these criteria and is therefore a direct electrical and mechanical equivalent. The primary distinction is packaging format (Tube vs. unspecified for the original) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P1304UBLTP is the direct substitute for the P1304UBTP. Both components are electrically and mechanically identical across all specified parameters. The P1304UBLTP is preferred for new designs and ongoing applications due to its Active product status and ROHS3 compliance, whereas the P1304UBTP is classified as Obsolete. For applications requiring RoHS compliance, the P1304UBLTP is the appropriate selection. Both components share identical electrical performance, package configuration, and thermal characteristics, making them interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the P1304UBLTP directly replace the P1304UBTP in existing designs?

A: Yes. The P1304UBLTP is electrically and mechanically equivalent to the P1304UBTP across all specified parameters, including voltage ratings, current ratings, element count, capacitance, and package configuration (6-SMD, Gull Wing; Modified MS-013).

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

A: The P1304UBTP is classified as Obsolete, while the P1304UBLTP is Active. Additionally, the P1304UBLTP is ROHS3 compliant, whereas the P1304UBTP is RoHS non-compliant. Packaging format differs (Tube for P1304UBLTP).

Q: Are there any performance differences between these components?

A: No. Both parts maintain identical electrical specifications: 120V/240V off-state voltage, 250 A peak pulse current (8/20µs), 80 A peak pulse current (10/1000µs), 150 mA hold current, and 4V on-state voltage.

Q: Is the P1304UBLTP suitable for new product designs?

A: Yes. The P1304UBLTP is the recommended choice for new designs due to its Active status and ROHS3 compliance certification.

Q: Do these components require different PCB layouts or mounting procedures?

A: No. Both components use identical Surface Mount technology with 6-SMD Gull Wing package configuration and Modified MS-013 supplier device package, requiring no layout or assembly modifications.
