P0904UCTP Equivalent & Substitute Parts

Part Overview

The P0904UCTP 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 75V/175V off-state voltage rating with 400A peak pulse current capability in a 6-SMD Gull Wing package. The part is currently classified as obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P0904UCTP 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 values
• Physical package configuration (6-SMD, Gull Wing)
• Mounting type (Surface Mount)

The P0904UCLTP qualifies as a direct substitute based on complete alignment with all specified electrical characteristics and mechanical form factor requirements.

Parameter Comparison

Engineering Selection Recommendations

The P0904UCLTP is the direct functional equivalent of the P0904UCTP. Both components share identical electrical specifications and mechanical packaging. The primary distinction is product lifecycle status: the P0904UCTP is obsolete while the P0904UCLTP maintains active production status.

For new designs or component replenishment, the P0904UCLTP is the appropriate selection. This part offers the additional advantage of ROHS3 compliance, whereas the original P0904UCTP does not meet current RoHS requirements. Both parts are available in equivalent quantities from current inventory.

Frequently Asked Questions (FAQ)

Q: Can P0904UCLTP replace P0904UCTP in existing applications?

A: Yes. The P0904UCLTP provides identical electrical performance and mechanical compatibility. All voltage ratings, current specifications, and package dimensions are equivalent.

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

A: The primary differences are product status and RoHS compliance. The P0904UCTP is obsolete and RoHS non-compliant. The P0904UCLTP is actively produced and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the same 6-SMD Gull Wing package configuration (Modified MS-013). The P0904UCLTP is supplied in tube packaging, while the P0904UCTP packaging specification was not provided.

Q: What parameters must match for a valid TVS thyristor substitution?

A: Voltage ratings (Breakover, Off-State, On-State), peak pulse current values, hold current, element count, capacitance, and package form factor must all be identical for direct substitution in TVS thyristor applications.

Q: Is the P0904UCLTP suitable for new product designs?

A: Yes. The active production status and ROHS3 compliance make the P0904UCLTP the appropriate choice for new designs requiring this voltage and current rating combination.
