Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0901UARP is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 98V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 4 (exact match required)
• Applications: SLIC (exact match required)
• Package / Case: 6-SMD, Gull Wing (exact match required)
• Supplier Device Package: MS-013 (exact match required)
• Series: TwinSLIC™ (exact match required)

The P0901UALRP qualifies as a direct substitute based on complete alignment with all critical electrical and mechanical parameters. The primary distinction between these parts is packaging format and product status, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The P0901UALRP is the direct substitute for the obsolete P0901UARP. Both parts are functionally equivalent across all critical electrical and mechanical parameters. The P0901UALRP offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The P0901UALRP achieves ROHS3 compliance, whereas the P0901UARP is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the P0901UALRP is the appropriate selection. The P0901UALRP is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes, whereas the P0901UARP is supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the P0901UALRP be used as a direct replacement for the P0901UARP?

A: Yes. The P0901UALRP is a direct substitute. Both parts share identical electrical specifications (98V clamping voltage, mixed technology, four circuits) and mechanical specifications (6-SMD Gull Wing package, MS-013 supplier device package). The primary differences are product status and packaging format.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging (P0901UARP) is suitable for manual handling and small-quantity applications. Tape & Reel packaging (P0901UALRP) is designed for automated pick-and-place assembly equipment and high-volume production. Both formats contain the same component.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical circuit protection characteristics. The ROHS3 compliance of the P0901UALRP makes it suitable for applications in regulated markets.

Q: Why is the P0901UARP classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production. The P0901UALRP remains in active production and is the recommended source for new designs and ongoing supply requirements.

Q: Are there any compatibility concerns when substituting the P0901UALRP for the P0901UARP?

A: No compatibility concerns exist. The parts are pin-compatible, functionally equivalent, and mechanically interchangeable. PCB layouts, footprints, and circuit designs require no modification.
