P3104UBTP Equivalent & Substitute Parts

Part Overview

The P3104UBTP is a Transient Voltage Suppressor (TVS) thyristor from Littelfuse Inc.'s SIDACtor® series, designed for overvoltage protection in surface mount applications. This component features dual voltage ratings (275V/550V off-state) with a peak pulse current capability of 250 A at 8/20µs pulse width. The part is currently classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Direct substitution for the P3104UBTP is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings (Breakover: 350V/700V; Off-State: 275V/550V)
• Peak pulse current capability (250 A at 8/20µs; 80 A at 10/1000µs)
• Hold current (150 mA)
• On-state voltage (4 V)
• Physical package configuration (6-SMD, Gull Wing; Modified MS-013)
• Number of internal elements (4)
• Capacitance characteristics (45pF, 80pF)

The P3104UBLTP meets all these criteria and is classified as a direct manufacturer equivalent, differing only in packaging format (tube versus bulk) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P3104UBLTP is the direct functional equivalent of the P3104UBTP. Both components share identical electrical specifications and physical packaging, ensuring pin-for-pin and functional compatibility in circuit applications.

Selection between these parts should be based on the following factors:

For new designs and production: The P3104UBLTP is the appropriate choice due to its active product status and ROHS3 compliance certification. This ensures long-term supply availability and regulatory alignment with current environmental standards.

For legacy system maintenance: The P3104UBTP may be used where existing inventory is available; however, transition to P3104UBLTP is recommended to avoid future supply constraints associated with obsolete components.

Packaging consideration: The P3104UBLTP is supplied in tube packaging, which may affect procurement workflows compared to bulk packaging formats. Verify packaging requirements with your supply chain management process.

Frequently Asked Questions (FAQ)

Q: Can P3104UBLTP be used as a direct replacement for P3104UBTP in existing designs?

A: Yes. The P3104UBLTP is electrically and mechanically identical to the P3104UBTP. All electrical parameters, including voltage ratings, current ratings, and on-state characteristics, are matched. The 6-SMD Gull Wing package configuration and pin assignments are identical, enabling direct substitution without circuit modification.

Q: What is the primary difference between P3104UBTP and P3104UBLTP?

A: The primary differences are product status and regulatory compliance. The P3104UBTP is obsolete and RoHS non-compliant, while the P3104UBLTP is an active product with ROHS3 compliance. Packaging format also differs: P3104UBLTP is supplied in tube packaging. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with the 6-SMD Gull Wing package?

A: No compatibility concerns exist between the two parts. Both use the Modified MS-013 supplier device package with identical 6-SMD Gull Wing configuration. PCB footprints, solder pad layouts, and component placement requirements are identical.

Q: Why is RoHS3 compliance important for the P3104UBLTP?

A: ROHS3 compliance ensures the component meets current environmental and regulatory requirements for restricted substances. This is particularly important for products destined for European markets and for organizations with environmental compliance mandates. The obsolete P3104UBTP does not carry this certification.

Q: Can I use P3104UBLTP in applications originally designed for P3104UBTP?

A: Yes, without modification. The electrical performance, including breakover voltage (350V/700V), off-state voltage (275V/550V), peak pulse current (250 A at 8/20µs), and all other specifications are identical. The component will function identically in the original circuit.
