B3104UCTP Equivalent & Substitute Parts

Part Overview

The B3104UCTP is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., designed for circuit protection applications in SLIC systems. This component features adjustable voltage clamping with mixed technology in a 6-SMD, Gull Wing surface mount package. The B3104UCTP is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B3104UCTP is determined by strict equivalence across the following critical parameters:

• Package / Case: 6-SMD, Gull Wing (ensures PCB footprint compatibility)
• Supplier Device Package: MS-013 (maintains mechanical and electrical interface)
• Voltage - Clamping: Adjustable (functional requirement for circuit protection)
• Technology: Mixed Technology (electrical performance characteristic)
• Number of Circuits: 1 (functional configuration)
• Applications: SLIC (intended use case)
• Mounting Type: Surface Mount (assembly process compatibility)

The B3104UCLTP meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The B3104UCLTP is the direct substitute for the B3104UCTP. Both components share identical electrical and mechanical specifications, ensuring drop-in compatibility at the PCB level.

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

• Product Availability: The B3104UCTP is obsolete. The B3104UCLTP is active and currently in production, making it the appropriate choice for new designs and ongoing procurement.
• Regulatory Compliance: The B3104UCLTP is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The B3104UCTP does not meet these standards.
• Supply Chain Continuity: Use of the B3104UCLTP ensures long-term component availability and reduces obsolescence risk.

For applications where the B3104UCTP is currently specified, direct substitution with the B3104UCLTP is supported without circuit redesign or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the B3104UCLTP be used as a direct replacement for the B3104UCTP?

A: Yes. Both components are electrically and mechanically identical. The B3104UCLTP shares the same package (6-SMD, Gull Wing), supplier device package (MS-013), voltage clamping (adjustable), technology (mixed), circuit count (1), and applications (SLIC). No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The B3104UCTP is obsolete, while the B3104UCLTP is active. Additionally, the B3104UCLTP is ROHS3 compliant and REACH unaffected, whereas the B3104UCTP is RoHS non-compliant. Functionally, they are equivalent.

Q: Are there any packaging differences?

A: The B3104UCLTP is supplied in tube packaging, while the B3104UCTP packaging is not specified. Both use the same MS-013 supplier device package and 6-SMD, Gull Wing case format, ensuring identical PCB footprint and assembly compatibility.

Q: Why should I transition from the B3104UCTP to the B3104UCLTP?

A: The B3104UCTP is obsolete and no longer manufactured. The B3104UCLTP is the active equivalent, ensuring continued availability, regulatory compliance, and supply chain stability.

Q: Is re-qualification required when switching to the B3104UCLTP?

A: No re-qualification is necessary. The components are functionally equivalent across all critical electrical and mechanical parameters. Standard engineering change procedures apply based on your organization's requirements.
