P2604UBTP Equivalent & Substitute Parts

Part Overview

The P2604UBTP is a SIDACtor® Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in 220V and 440V 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 equivalent substitute parts with matching electrical and mechanical specifications is essential for system continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2604UBTP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (Breakover: 300V/600V; Off-State: 220V/440V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 250 A; Peak Pulse 10/1000µs: 80 A; Hold Current: 150 mA)
• Number of elements (4)
• Capacitance range (50pF, 85pF)
• Mounting type and package configuration (Surface Mount, 6-SMD Gull Wing, Modified MS-013)

The P2604UBLTP qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is packaging format (Tube vs. unspecified for the main part) and product status (Active vs. Obsolete), with the substitute offering improved compliance and availability.

Parameter Comparison

Engineering Selection Recommendations

The P2604UBLTP is the direct equivalent substitute for the obsolete P2604UBTP. Both components share identical electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs. The P2604UBLTP offers the advantage of Active product status, ensuring continued availability and supply chain reliability. Additionally, the P2604UBLTP meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. For new designs or component replacement in systems requiring regulatory compliance, the P2604UBLTP is the appropriate selection. Both parts maintain identical Moisture Sensitivity Level (MSL) ratings and ECCN/HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the P2604UBLTP be used as a direct replacement for the P2604UBTP?

A: Yes. The P2604UBLTP is electrically and mechanically equivalent to the P2604UBTP across all critical parameters: voltage ratings, current specifications, element count, capacitance, and package configuration. Both components are 6-SMD Gull Wing surface mount devices with identical Modified MS-013 supplier packages.

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

A: The main differences are product status and compliance. The P2604UBTP is obsolete, while the P2604UBLTP is active. The P2604UBLTP is ROHS3 compliant, whereas the P2604UBTP is RoHS non-compliant. Packaging format differs (Tube for P2604UBLTP).

Q: Are there any electrical performance differences?

A: No. Both parts have identical electrical specifications: 220V/440V off-state voltage, 300V/600V breakover voltage, 4V on-state voltage, 250 A peak pulse current (8/20µs), 80 A peak pulse current (10/1000µs), 150 mA hold current, and 50pF/85pF capacitance ratings.

Q: Will the P2604UBLTP work in existing PCB layouts designed for the P2604UBTP?

A: Yes. Both components use identical 6-SMD Gull Wing package configurations with the same Modified MS-013 supplier package specification, ensuring footprint and pinout compatibility.

Q: Is the P2604UBLTP suitable for new designs?

A: Yes. The P2604UBLTP is the recommended choice for new designs due to its active product status, ROHS3 compliance, and guaranteed availability from Littelfuse Inc.
