P1304UBRP Equivalent & Substitute Parts

Part Overview

The P1304UBRP 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 functionally equivalent substitute parts is essential for ongoing system maintenance and new design implementations where this protection topology is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P1304UBRP 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: 250 A; Peak Pulse 10/1000µs: 80 A; Hold Current: 150 mA)
• Element count (4 elements)
• Capacitance range (60pF, 105pF)
• Physical package (6-SMD, Gull Wing; Modified MS-013)
• Series designation (SIDACtor®)

The P1304UBLRP meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is packaging format and product status.

Engineering Selection Recommendations

The P1304UBLRP is the direct substitute for the P1304UBRP. Both parts are electrically and mechanically identical across all functional parameters. Selection between these parts should be based on the following factors:

Product Status: The P1304UBRP is obsolete, while the P1304UBLRP is active. For new designs or ongoing production, the P1304UBLRP is the appropriate choice.

Regulatory Compliance: The P1304UBLRP is ROHS3 compliant, whereas the P1304UBRP is RoHS non-compliant. Applications subject to RoHS requirements must use the P1304UBLRP.

Packaging Format: The P1304UBRP is supplied in bulk packaging, while the P1304UBLRP is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes and reduces handling and contamination risk.

Frequently Asked Questions (FAQ)

Q: Can the P1304UBLRP be used as a direct replacement for the P1304UBRP in existing designs?

A: Yes. The P1304UBLRP is electrically and mechanically equivalent to the P1304UBRP across all specified parameters, including voltage ratings, current ratings, element count, capacitance, and physical package dimensions. No circuit modifications are required.

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

A: The primary differences are product status (obsolete vs. active), packaging format (bulk vs. Tape & Reel), and RoHS compliance status (non-compliant vs. ROHS3 compliant). All electrical and mechanical specifications are identical.

Q: Is the Tape & Reel packaging compatible with existing PCB assembly equipment?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. If your assembly process currently uses bulk packaging, conversion to Tape & Reel format is straightforward and does not affect component performance or reliability.

Q: Are there any compliance considerations when switching from P1304UBRP to P1304UBLRP?

A: The P1304UBLRP is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to environmental and regulatory restrictions. The P1304UBRP is RoHS non-compliant and may not be acceptable in regulated markets.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the P1304UBRP and P1304UBLRP have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
