P1104UBTP Equivalent & Substitute Parts

Part Overview

The P1104UBTP 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 90V/180V off-state voltage rating with 250A peak pulse current capability in a 6-SMD Gull Wing package. The P1104UBTP 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

The P1104UBTP has one direct substitute: the P1104UBLTP. Substitution eligibility is determined by the following critical parameters:

• Voltage ratings (Breakover, Off-State, and On-State) must be identical
• Peak pulse current ratings (8/20µs and 10/1000µs) must match
• Hold current (Ih) must be equivalent
• Number of elements must be the same
• Capacitance values must align
• Package type and mounting configuration must be identical
• Supplier device package designation must be compatible

The P1104UBLTP meets all these criteria, differing only in packaging format (Tube versus unspecified for the original) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P1104UBLTP is the direct substitute for the P1104UBTP. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications. The primary distinction is product status: the P1104UBTP is obsolete while the P1104UBLTP is active in production.

For new designs and ongoing system support, the P1104UBLTP is the appropriate selection. This part offers the additional advantage of ROHS3 compliance, whereas the original P1104UBTP is RoHS non-compliant. Both components maintain identical moisture sensitivity levels and export classifications (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the P1104UBLTP be used as a direct replacement for the P1104UBTP?

A: Yes. The P1104UBLTP is electrically and mechanically identical to the P1104UBTP. All voltage ratings, current specifications, capacitance values, and package configurations are equivalent. The components are interchangeable at the circuit level.

Q: What is the difference between the P1104UBTP and P1104UBLTP?

A: The primary differences are packaging format (Tube for P1104UBLTP) and product status (Active versus Obsolete). The P1104UBLTP also carries ROHS3 compliance certification, whereas the P1104UBTP is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Why is the P1104UBTP listed as obsolete?

A: The P1104UBTP has been discontinued by Littelfuse Inc. The P1104UBLTP serves as the active production equivalent and is the recommended part for current applications.

Q: Are there any compliance differences between these parts?

A: Yes. The P1104UBLTP is ROHS3 compliant, while the P1104UBTP is RoHS non-compliant. Both parts are REACH unaffected and carry the same EAR99 export classification. For applications requiring RoHS compliance, the P1104UBLTP is the appropriate choice.

Q: Does the package format affect circuit performance?

A: No. Both parts use identical 6-SMD Gull Wing packages with the Modified MS-013 supplier device package designation. Packaging format (Tube) does not affect electrical performance or mechanical fit.
