P1304UCTP Equivalent & Substitute Parts

Part Overview

The P1304UCTP is a SIDACtor® Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in 120V and 240V applications. This component features a 6-SMD Gull Wing package with a peak pulse current rating of 400 A (8/20µs) and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for system redesign, component sourcing, and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1304UCTP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (Breakover: 160V/320V; Off-State: 120V/240V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 400 A; Peak Pulse 10/1000µs: 100 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 P1304UCLTP meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging format, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The P1304UCLTP is the direct electrical and mechanical equivalent of the P1304UCTP. All voltage, current, and package specifications are identical. Selection between these parts should be based on the following factors:

• Product Status: The P1304UCTP is obsolete, while P1304UCLTP is active and currently manufactured. For new designs or long-term supply requirements, P1304UCLTP is the appropriate choice.
• RoHS Compliance: P1304UCLTP is ROHS3 compliant, whereas P1304UCTP is non-compliant. Applications subject to RoHS regulations require P1304UCLTP.
• Packaging Format: P1304UCLTP is supplied in tube packaging, which may affect procurement and assembly workflows compared to the original part's packaging.

Frequently Asked Questions (FAQ)

Q: Can P1304UCLTP be used as a direct replacement for P1304UCTP in existing designs?

A: Yes. The P1304UCLTP is electrically and mechanically identical to P1304UCTP across all specified parameters: voltage ratings, current ratings, element count, capacitance, and 6-SMD Gull Wing package configuration. No circuit modifications are required.

Q: What is the difference between P1304UCTP and P1304UCLTP?

A: The parts are functionally equivalent. The primary differences are: P1304UCTP is obsolete while P1304UCLTP is active; P1304UCTP is RoHS non-compliant while P1304UCLTP is ROHS3 compliant; and packaging format differs (tube for P1304UCLTP).

Q: Does the tube packaging of P1304UCLTP affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. Tube packaging is a supply and handling consideration only. The component itself maintains identical form factor and performance characteristics.

Q: Are there any compliance considerations when switching from P1304UCTP to P1304UCLTP?

A: Yes. If your application or market requires RoHS compliance, P1304UCLTP is mandatory. P1304UCTP does not meet ROHS3 standards. Additionally, P1304UCLTP has REACH Unaffected status, providing regulatory clarity for EU applications.

Q: What parameters determine substitution eligibility for this TVS thyristor?

A: Substitution is determined by exact equivalence in: breakover voltage (160V/320V), off-state voltage (120V/240V), on-state voltage (4V), peak pulse current (400 A at 8/20µs), hold current (150 mA), element count (4), capacitance (60pF/105pF), and package type (6-SMD Gull Wing, Modified MS-013).
