Key Parameters

Substitute Part Grouping Explanation

Substitution of the B1101UC4TP is determined by strict equivalence across the following critical parameters:

• Voltage clamping characteristic: Adjustable
• Technology platform: Mixed Technology
• Circuit count: 1
• Application domain: SLIC
• Mounting configuration: Surface Mount
• Physical package: 6-SMD, Gull Wing
• Supplier device package designation: MS-013
• Moisture sensitivity rating: MSL 1 (Unlimited)

The B1101UC4LTP meets all these criteria and is classified as a direct substitute. Both components share identical functional specifications, package geometry, and environmental ratings, differing only in product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The B1101UC4LTP is the direct functional equivalent of the B1101UC4TP. Selection between these components should be based on the following criteria:

For new designs and ongoing production requiring regulatory compliance, the B1101UC4LTP is the appropriate choice. This part maintains active product status with Littelfuse Inc. and carries ROHS3 compliance certification, meeting current environmental and regulatory standards.

For legacy system support where existing inventory of B1101UC4TP components is available, continued use is permissible provided that RoHS non-compliance does not conflict with system-level requirements or end-market regulations.

Both components are electrically and mechanically interchangeable within SLIC circuit protection applications, with identical performance characteristics across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can B1101UC4LTP be used as a direct replacement for B1101UC4TP?

A: Yes. Both components are electrically and mechanically equivalent. They share identical voltage clamping characteristics, technology platform, circuit configuration, mounting type, and package specification (MS-013). The primary differences are product status and RoHS compliance level.

Q: What is the difference between the two part numbers?

A: The B1101UC4TP is classified as obsolete with RoHS non-compliance status. The B1101UC4LTP is an active product with ROHS3 compliance. Both are manufactured by Littelfuse Inc. in the Battrax® series and function identically in SLIC applications.

Q: Are there packaging differences between B1101UC4TP and B1101UC4LTP?

A: The physical component package (6-SMD, Gull Wing, MS-013) is identical. The primary packaging difference is the distribution format: B1101UC4TP is supplied in standard packaging, while B1101UC4LTP is supplied in tube packaging.

Q: Which part should be specified for new designs?

A: The B1101UC4LTP should be specified for new designs. It maintains active product status and carries current RoHS compliance certification, ensuring long-term availability and regulatory alignment.

Q: Are both parts suitable for SLIC applications?

A: Yes. Both the B1101UC4TP and B1101UC4LTP are designed and rated for SLIC (Subscriber Line Interface Circuit) applications with identical performance specifications.
