Substitute Part Grouping Explanation

Substitution of the P1101UARP 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

The P1101UALRP qualifies as a direct substitute based on matching all electrical and mechanical specifications. The primary distinction between these parts is product status and packaging format, with P1101UALRP representing the active production equivalent available in Tape & Reel packaging.

Parameter Comparison

Engineering Selection Recommendations

The P1101UALRP is the direct functional equivalent of the obsolete P1101UARP. Both parts maintain identical electrical performance characteristics and physical form factors. The P1101UALRP is the recommended selection for new designs and replacement applications due to its active product status and ROHS3 compliance. The transition from bulk packaging to Tape & Reel format in the P1101UALRP aligns with standard manufacturing and assembly practices for surface mount components. For legacy systems currently using P1101UARP, the P1101UALRP provides seamless compatibility without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can P1101UALRP be used as a direct replacement for P1101UARP in existing designs?

A: Yes. The P1101UALRP is electrically and mechanically equivalent to the P1101UARP. Both parts share identical clamping voltage (130V), circuit count (4), technology type (Mixed), and physical package specifications (6-SMD, Gull Wing, MS-013). The primary difference is product status and packaging format.

Q: What is the significance of the product status change from Obsolete to Active?

A: The P1101UALRP is in active production, ensuring long-term availability and supply chain stability. The P1101UARP, classified as obsolete, has limited or no manufacturing support. For new designs and ongoing production, the P1101UALRP is the appropriate selection.

Q: Does the Tape & Reel packaging of P1101UALRP affect compatibility?

A: No. Tape & Reel is a standard packaging format for surface mount components and does not affect electrical or mechanical compatibility. The component itself remains identical; only the delivery and handling format differs.

Q: Are there compliance differences between these parts?

A: The P1101UALRP is ROHS3 compliant, while the P1101UARP is RoHS non-compliant. Both parts maintain identical Moisture Sensitivity Level (MSL 1) and export classification (EAR99). For applications requiring RoHS compliance, the P1101UALRP is the appropriate choice.

Q: What parameters must remain constant for substitution validity?

A: Voltage - Clamping (130V), Technology (Mixed), Number of Circuits (4), Applications (SLIC), Mounting Type (Surface Mount), Package / Case (6-SMD, Gull Wing), and Supplier Device Package (MS-013) must all match for valid substitution.
