P1104UBRP Equivalent & Substitute Parts

Part Overview

The P1104UBRP is a SIDACtor® Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in electronic circuits. This component features a 90V/180V off-state voltage rating with 250A peak pulse current capability in a 6-SMD Gull Wing surface mount package. The P1104UBRP is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support. Direct substitutes maintain identical electrical performance and mechanical compatibility while offering current product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The P1104UBLRP qualifies as a direct substitute for the P1104UBRP based on identical electrical and mechanical parameters. Substitution is determined by the following criteria:

• Voltage ratings (breakover, off-state, and on-state) must match exactly
• Peak pulse current specifications (8/20µs and 10/1000µs) must be identical
• Hold current (Ih) must be equivalent
• Number of internal elements must match
• Capacitance values must be the same
• Package type and mounting configuration must be identical (6-SMD, Gull Wing, Modified MS-013)

The P1104UBLRP maintains all these parameters while offering active product status and improved RoHS compliance, making it suitable for direct replacement in applications currently using the P1104UBRP.

Engineering Selection Recommendations

The P1104UBLRP is the direct equivalent for the obsolete P1104UBRP. Selection between these parts is determined by product availability and compliance requirements:

• The P1104UBRP is obsolete with limited remaining inventory (772 pcs). New designs should transition to the P1104UBLRP.
• The P1104UBLRP is active with current availability (827 pcs) and offers ROHS3 compliance, meeting modern regulatory requirements.
• Both parts are classified as RoHS non-compliant or ROHS3 compliant respectively, with the P1104UBLRP providing superior compliance status for applications subject to RoHS directives.
• Packaging differs only in format: P1104UBRP uses standard packaging while P1104UBLRP is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
• Both parts carry identical ECCN (EAR99) and HTSUS classifications, with no export or tariff implications affecting substitution.

Frequently Asked Questions (FAQ)

Q: Can the P1104UBLRP replace the P1104UBRP in existing designs?

A: Yes. The P1104UBLRP is a direct electrical and mechanical equivalent. All voltage ratings, current specifications, capacitance values, and package dimensions are identical. The only differences are product status (active vs. obsolete) and RoHS compliance level.

Q: What is the difference between the packaging formats?

A: The P1104UBRP uses standard packaging, while the P1104UBLRP is supplied in Tape & Reel (TR) format. Both contain the same component in the 6-SMD Gull Wing configuration. Tape & Reel packaging is optimized for high-volume automated assembly.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical electrical specifications: 90V/180V off-state voltage, 130V/260V breakover voltage, 4V on-state voltage, 250A peak pulse current (8/20µs), 80A peak pulse current (10/1000µs), 150mA hold current, and 65pF/115pF capacitance values.

Q: Why should I choose the P1104UBLRP over the P1104UBRP?

A: The P1104UBLRP offers active product status with current manufacturing support and ROHS3 compliance. The P1104UBRP is obsolete with limited inventory. For new designs and long-term production, the P1104UBLRP is the appropriate selection.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Do these parts have identical regulatory classifications?

A: Yes. Both parts carry EAR99 ECCN and 8541.30.0080 HTSUS classifications, with no differences in export control or tariff treatment.
