P2604UCMCTP Equivalent & Substitute Parts

Part Overview

The P2604UCMCTP is a Transient Voltage Suppressor (TVS) thyristor from Littelfuse Inc.'s SIDACtor® series, 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 400A (8/20µs). The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2604UCMCTP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (Breakover: 300V/600V; Off-State: 220V/440V; On-State: 8V)
• Current specifications (Peak Pulse 8/20µs: 400A; Peak Pulse 10/1000µs: 100A; Hold Current: 150mA)
• Element count (4 elements)
• Capacitance range (30pF, 45pF)
• Physical form factor (6-SMD, Gull Wing package; Modified MS-013)

The P2604UCMCLTP meets all these criteria and serves as a direct functional equivalent. The primary distinction between these parts is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The P2604UCMCLTP is the appropriate substitute for the obsolete P2604UCMCTP. Both components are electrically and mechanically identical across all specified parameters. The P2604UCMCLTP offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and systems requiring current regulatory adherence. The packaging difference (Tube vs. unspecified for the original) does not affect functional compatibility. Current inventory availability (1052 pcs) supports procurement for both replacement and new implementation scenarios.

Frequently Asked Questions (FAQ)

Q: Can P2604UCMCLTP be used as a direct replacement for P2604UCMCTP in existing designs?

A: Yes. Both components share identical electrical ratings (voltage, current, capacitance) and mechanical specifications (6-SMD Gull Wing package, Modified MS-013). No circuit modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The P2604UCMCTP is obsolete and no longer manufactured. The P2604UCMCLTP is actively produced, ensuring long-term availability and supply chain reliability for ongoing applications.

Q: Does the RoHS compliance difference affect substitution?

A: The P2604UCMCLTP's ROHS3 compliance is an advantage for new designs and systems subject to environmental regulations. For legacy system maintenance, both parts are functionally equivalent. Compliance requirements depend on your application's regulatory context.

Q: Are there packaging considerations when substituting these parts?

A: The P2604UCMCLTP is supplied in Tube packaging, while the original part's packaging is unspecified. Both use the same Modified MS-013 supplier device package. Verify your assembly equipment compatibility with Tube packaging if this is a concern.

Q: What parameters must remain constant for substitution to be valid?

A: Voltage ratings (Breakover, Off-State, On-State), peak pulse current (8/20µs and 10/1000µs), hold current, element count, capacitance range, and physical package form must all match. The P2604UCMCLTP meets all these requirements.
