P1504UCTP Equivalent & Substitute Parts

Part Overview

The P1504UCTP is a Transient Voltage Suppressor (TVS) thyristor from Littelfuse Inc.'s SIDACtor® series, designed for overvoltage protection in surface mount applications. This component features a 6-SMD Gull Wing package with dual voltage ratings (140V/280V off-state) and 400A peak pulse current capability. The P1504UCTP is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1504UCTP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings (Breakover, Off-State, and On-State)
• Peak pulse current specifications (8/20µs and 10/1000µs)
• Hold current (Ih)
• Number of internal elements
• Capacitance range
• Physical package type and form factor (6-SMD, Gull Wing)
• Supplier device package designation

The P1504UCLTP qualifies as a direct substitute based on identical electrical performance and mechanical compatibility across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The P1504UCLTP is the direct substitute for the obsolete P1504UCTP. Both components share identical electrical specifications and mechanical form factors, ensuring functional equivalence in circuit applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The P1504UCTP is obsolete and RoHS non-compliant, while the P1504UCLTP maintains active production status and meets ROHS3 compliance requirements. For new designs and ongoing system support, the P1504UCLTP is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the P1504UCLTP directly replace the P1504UCTP in existing designs?

A: Yes. The P1504UCLTP provides identical electrical performance and mechanical compatibility. No circuit modifications are required.

Q: What is the primary difference between these two part numbers?

A: The P1504UCTP is obsolete and RoHS non-compliant. The P1504UCLTP is an active production part with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between P1504UCTP and P1504UCLTP?

A: Both parts use the same 6-SMD Gull Wing package (Modified MS-013). The P1504UCLTP is supplied in tube packaging, while the P1504UCTP packaging specification was not provided.

Q: What voltage ratings apply to this TVS thyristor?

A: The component operates with breakover voltages of 180V and 360V, with off-state voltage ratings of 140V and 280V. On-state voltage is 4V.

Q: What is the peak pulse current capability?

A: The component handles 400A peak pulse current at 8/20µs and 100A at 10/1000µs pulse durations.
