P1701UARP Equivalent & Substitute Parts

Part Overview

The P1701UARP is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., designed for circuit protection in SLIC applications. This mixed-technology TVS operates at 200V clamping voltage and features four circuits in a 6-SMD, Gull Wing surface mount package. The P1701UARP is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1701UARP is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 200V
• 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 P1701UALRP qualifies as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P1701UALRP is the direct substitute for the obsolete P1701UARP. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in SLIC circuit protection applications.

Key selection factors:

• The P1701UALRP carries Active product status, ensuring continued manufacturer support and availability.
• The P1701UALRP is ROHS3 compliant, whereas the P1701UARP is RoHS non-compliant. Systems requiring RoHS compliance must use the P1701UALRP.
• Both components maintain MSL 1 (Unlimited) moisture sensitivity rating.
• Packaging format differs: P1701UARP is supplied in bulk; P1701UALRP is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the P1701UALRP be used as a direct replacement for the P1701UARP?

A: Yes. Both components are electrically and mechanically identical, with matching 200V clamping voltage, mixed-technology design, four-circuit configuration, and MS-013 package specification. The P1701UALRP is the active production equivalent.

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

A: The primary differences are product status (P1701UARP is obsolete; P1701UALRP is active) and RoHS compliance (P1701UARP is non-compliant; P1701UALRP is ROHS3 compliant). Packaging format also differs: bulk versus Tape & Reel.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and bulk packaging formats contain identical components. Packaging format selection is determined by assembly process requirements and inventory management practices.

Q: Are there any compatibility concerns when substituting the P1701UALRP for the P1701UARP?

A: No compatibility concerns exist. Identical electrical specifications, mechanical dimensions, and pinout ensure direct substitution without circuit modification.

Q: Which part should be specified for new designs?

A: The P1701UALRP should be specified for new designs. It is the active production part with current manufacturer support and RoHS3 compliance.
