P1504UBTP Equivalent & Substitute Parts

Part Overview

The P1504UBTP 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 140V/280V off-state voltage rating with 250A peak pulse current capability in a 6-SMD Gull Wing package. The P1504UBTP is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the P1504UBTP is determined by electrical and mechanical parameter equivalence. The following criteria establish direct substitutability:

• Voltage ratings (Breakover, Off-State, and On-State) must match exactly
• Peak pulse current ratings (8/20µs and 10/1000µs) must match exactly
• Hold current (Ih) must match exactly
• Number of elements must match exactly
• Capacitance values must match exactly
• Package type (6-SMD, Gull Wing) must match exactly
• Mounting type (Surface Mount) must match exactly
• Supplier device package (Modified MS-013) must match exactly

The P1504UBLTP meets all these criteria and is identified as a direct substitute for the obsolete P1504UBTP.

Parameter Comparison

Engineering Selection Recommendations

The P1504UBLTP is the direct substitute for the obsolete P1504UBTP. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance: the P1504UBLTP is an active product with ROHS3 compliance, whereas the P1504UBTP is obsolete and RoHS non-compliant. For new designs and ongoing system support, the P1504UBLTP is the appropriate selection. Both components share identical moisture sensitivity levels and export classifications, ensuring equivalent handling and logistics requirements.

Frequently Asked Questions (FAQ)

Q: Can the P1504UBLTP be used as a direct replacement for the P1504UBTP?

A: Yes. The P1504UBLTP is electrically and mechanically equivalent to the P1504UBTP across all specified parameters, including voltage ratings, current ratings, element count, capacitance, and package configuration.

Q: What is the difference between the P1504UBTP and P1504UBLTP?

A: The primary differences are product status and regulatory compliance. The P1504UBTP is obsolete and RoHS non-compliant, while the P1504UBLTP is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both components use the same 6-SMD Gull Wing package with Modified MS-013 supplier device package designation. The P1504UBLTP is supplied in tube packaging, while the P1504UBTP packaging type was not specified in the available data.

Q: Does the P1504UBLTP have the same moisture sensitivity as the P1504UBTP?

A: Yes. Both components have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are export classifications the same for both parts?

A: Yes. Both the P1504UBTP and P1504UBLTP share identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications.
