Key Parameters

Substitute Part Grouping Explanation

Substitution of the B1201UCTP is determined by strict equivalence across the following critical parameters:

• Base Product Number: B1201
• Voltage Clamping Characteristic: Adjustable
• Technology: Mixed Technology
• Number of Circuits: 1
• Mounting Type: Surface Mount
• Package / Case: 6-SMD, Gull Wing
• Supplier Device Package: MS-013
• Applications: SLIC

The B1201UCLTP qualifies as a direct substitute based on identical alignment across all these parameters. The primary distinction between the main part and its substitute is product status and packaging format, not electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The B1201UCLTP is the direct equivalent substitute for the B1201UCTP. Both components share identical electrical and mechanical specifications, including voltage clamping characteristics, technology platform, circuit configuration, and package geometry.

The B1201UCLTP offers two significant advantages over the obsolete B1201UCTP:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance satisfies current regulatory requirements, whereas the B1201UCTP is RoHS non-compliant

For applications requiring RoHS compliance or where long-term component availability is a consideration, the B1201UCLTP is the appropriate selection. Both parts are functionally interchangeable within SLIC circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Are B1201UCTP and B1201UCLTP electrically identical?

A: Yes. Both components feature adjustable voltage clamping, mixed technology, single-circuit configuration, and identical electrical performance characteristics for SLIC applications.

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

A: The B1201UCTP is obsolete, while the B1201UCLTP maintains active product status. Additionally, the B1201UCLTP is ROHS3 compliant, whereas the B1201UCTP is RoHS non-compliant. Packaging is supplied in tube format for the B1201UCLTP.

Q: Can I use B1201UCLTP as a direct replacement in existing designs?

A: Yes. The B1201UCLTP is mechanically and electrically compatible with the B1201UCTP. The 6-SMD, Gull Wing package geometry and MS-013 supplier device package are identical, ensuring PCB footprint compatibility.

Q: Does the tube packaging of B1201UCLTP affect compatibility?

A: No. Packaging format refers to how components are supplied for inventory and assembly purposes. The actual component package and electrical specifications remain unchanged.

Q: Why should I transition from B1201UCTP to B1201UCLTP?

A: The B1201UCTP is obsolete and subject to supply discontinuation. The B1201UCLTP ensures continued availability, regulatory compliance, and supply chain stability for new and ongoing production.
