Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1101UCTP is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 130V
• Technology: Mixed Technology
• Number of Circuits: 4
• Applications: SLIC
• Mounting Type: Surface Mount
• Package / Case: 6-SMD, Gull Wing
• Supplier Device Package: MS-013
• Moisture Sensitivity Level: 1 (Unlimited)

The P1101UCLTP qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction between these parts is product status and packaging format, with P1101UCLTP representing the active production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P1101UCLTP is the direct functional equivalent for applications currently using the P1101UCTP. Both parts share identical electrical specifications, circuit configuration, and mechanical packaging, ensuring pin-for-pin and functional compatibility.

For new designs and ongoing production, P1101UCLTP is the appropriate selection due to its active product status and ROHS3 compliance. The obsolete status of P1101UCTP restricts its availability and future manufacturability.

For legacy systems currently deployed with P1101UCTP, transition to P1101UCLTP presents no functional risk, as all critical parameters remain equivalent. The improved compliance profile of P1101UCLTP (ROHS3 and REACH Unaffected) provides additional regulatory alignment for systems subject to environmental standards.

Frequently Asked Questions (FAQ)

Q: Can P1101UCLTP directly replace P1101UCTP in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage rating, circuit count, package type, and mounting configuration. No design modifications are required.

Q: What is the primary difference between P1101UCTP and P1101UCLTP?

A: The primary differences are product status (obsolete versus active) and compliance certifications. P1101UCTP is RoHS non-compliant, while P1101UCLTP is ROHS3 compliant and REACH unaffected. Packaging format also differs (standard versus tube).

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical voltage clamping at 130V, mixed technology implementation, four-circuit configuration, and all other electrical specifications.

Q: What packaging options are available?

A: P1101UCTP is supplied in standard packaging, while P1101UCLTP is available in tube packaging. Both use the MS-013 supplier device package format.

Q: Is P1101UCLTP suitable for new production designs?

A: Yes. P1101UCLTP is the recommended choice for new designs due to its active product status and superior compliance certifications (ROHS3 and REACH Unaffected).

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
