Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1101UATP is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 130V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 4 (exact match required)
• Package / Case: 6-SMD, Gull Wing (exact match required)
• Supplier Device Package: MS-013 (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Applications: SLIC (exact match required)

The P1101UALTP meets all substitution criteria and is classified as a direct equivalent. This part maintains identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P1101UALTP is the direct equivalent substitute for the obsolete P1101UATP. Both components are manufactured by Littelfuse and share identical electrical and mechanical specifications across all critical parameters including clamping voltage, circuit count, package type, and SLIC application suitability.

The P1101UALTP offers significant advantages for new designs and replacement applications:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• REACH Unaffected status provides regulatory clarity for international applications
• Tube packaging facilitates standard component handling and assembly processes

For applications currently using the obsolete P1101UATP, direct substitution with P1101UALTP is electrically and mechanically compatible without circuit redesign or board modification.

Frequently Asked Questions (FAQ)

Q: Can P1101UALTP be used as a direct replacement for P1101UATP?

A: Yes. The P1101UALTP is a direct equivalent substitute. All electrical parameters (130V clamping voltage, mixed technology, four circuits) and mechanical specifications (6-SMD Gull Wing package, MS-013 supplier package) are identical. No circuit modifications are required.

Q: What is the primary reason to substitute P1101UATP with P1101UALTP?

A: The P1101UATP is classified as obsolete. The P1101UALTP maintains identical specifications while offering active product status, ensuring continued availability and manufacturer support.

Q: Are there compliance differences between these parts?

A: Yes. The P1101UALTP is ROHS3 compliant and REACH Unaffected, while the P1101UATP is RoHS non-compliant. For applications subject to environmental regulations, the P1101UALTP is the appropriate selection.

Q: Do these parts have different packaging options?

A: The P1101UALTP is supplied in Tube packaging. The P1101UATP packaging specification was not provided. Both parts use the same MS-013 supplier device package and 6-SMD Gull Wing case format.

Q: Are there inventory considerations for these parts?

A: Both parts are available in stock. The P1101UATP has 680 pieces available, while the P1101UALTP has 669 pieces available. Availability may vary based on current demand and supplier inventory levels.

Q: What applications are these TVS devices designed for?

A: Both the P1101UATP and P1101UALTP are designed for SLIC (Subscriber Line Interface Circuit) applications, providing transient voltage suppression and circuit protection in telecommunications and related systems.
