P2604UCTP Equivalent & Substitute Parts

Part Overview

The P2604UCTP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse, designed for 220V/440V off-state voltage applications with 400A peak pulse current capability in a 6-SMD gull wing surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The P2604UCTP serves critical overvoltage protection functions in industrial and commercial electrical systems requiring bidirectional transient suppression.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2604UCTP is determined by strict electrical and mechanical parameter matching across the following criteria:

Electrical Parameters (Critical):

• Voltage - Breakover: 300V, 600V
• Voltage - Off State: 220V, 440V
• Voltage - On State: 4 V
• Current - Peak Pulse (8/20µs): 400 A
• Current - Peak Pulse (10/1000µs): 100 A
• Current - Hold (Ih): 150 mA

Mechanical Parameters (Critical):

• Number of Elements: 4
• Capacitance: 50pF, 85pF
• Mounting Type: Surface Mount
• Package / Case: 6-SMD, Gull Wing
• Supplier Device Package: Modified MS-013

The P2604UCLTP meets all specified electrical and mechanical parameters, establishing it as a direct equivalent substitute. Both parts maintain identical functional characteristics within the SIDACtor® series.

Parameter Comparison

Engineering Selection Recommendations

The P2604UCLTP is the direct substitute for the obsolete P2604UCTP. Both components share identical electrical performance specifications and mechanical packaging. The P2604UCLTP carries active product status with ROHS3 compliance, whereas the P2604UCTP is classified as obsolete and RoHS non-compliant. For new designs and ongoing procurement, the P2604UCLTP is the appropriate selection. Both parts maintain equivalent MSL ratings and export classifications (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the P2604UCLTP directly replace the P2604UCTP in existing designs?

A: Yes. The P2604UCLTP provides identical electrical parameters (voltage ratings, current ratings, on-state voltage) and mechanical specifications (6-SMD gull wing package, Modified MS-013 supplier package, four-element configuration). Direct substitution is supported without circuit modification.

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

A: The P2604UCTP is obsolete with RoHS non-compliant status. The P2604UCLTP is an active product with ROHS3 compliance. Electrical and mechanical performance are equivalent.

Q: Are there packaging differences between P2604UCTP and P2604UCLTP?

A: Both parts use identical 6-SMD gull wing surface mount packaging with Modified MS-013 supplier device package designation. No package conversion is required for substitution.

Q: What are the critical electrical parameters for substitution compatibility?

A: Substitution requires matching voltage ratings (300V/600V breakover, 220V/440V off-state, 4V on-state), peak pulse current (400A at 8/20µs, 100A at 10/1000µs), hold current (150mA), element count (4), and capacitance range (50pF, 85pF).

Q: Is the P2604UCLTP suitable for RoHS-compliant applications?

A: Yes. The P2604UCLTP carries ROHS3 compliance certification, making it suitable for applications requiring RoHS compliance. The obsolete P2604UCTP does not meet RoHS requirements.
