P5106UARP Equivalent & Substitute Parts

Part Overview

The P5106UARP is a 420V off-state, 150A peak pulse TVS thyristor manufactured by Littelfuse Inc. in a 6-SMD gull wing surface mount package. This component belongs to the SIDACtor® series of transient voltage suppressors and is designed for overvoltage protection applications requiring high current handling capability.

The P5106UARP is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P5106UARP is determined by electrical and mechanical parameter equivalence within the SIDACtor® product family. The critical parameters governing substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Current handling specifications (peak pulse at 8/20µs and 10/1000µs, hold current)
• Element count and capacitance characteristics
• Physical package configuration (6-SMD gull wing)
• Surface mount mounting type

The P5106UALRP meets all these criteria as a direct electrical and mechanical equivalent, with the primary distinction being packaging format (tape & reel versus bulk) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P5106UALRP is the direct substitute for the obsolete P5106UARP. Both components share identical electrical specifications and mechanical package configurations, ensuring functional equivalence in circuit applications.

The P5106UALRP offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the P5106UALRP meets ROHS3 compliance requirements, whereas the P5106UARP is non-compliant. For new designs or systems requiring regulatory compliance, the P5106UALRP is the appropriate selection.

The packaging difference (tape & reel for P5106UALRP versus bulk for P5106UARP) affects procurement and assembly processes but does not impact electrical or mechanical performance. Selection between these formats depends on production volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Can the P5106UALRP be used as a direct replacement for the P5106UARP?

A: Yes. The P5106UALRP is electrically and mechanically equivalent to the P5106UARP. All voltage ratings, current specifications, element count, capacitance values, and package configuration are identical.

Q: What is the difference between the P5106UARP and P5106UALRP?

A: The primary differences are product status (obsolete versus active), packaging format (bulk versus tape & reel), and RoHS compliance (non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Does the tape & reel packaging of the P5106UALRP affect circuit performance?

A: No. Packaging format affects procurement, storage, and assembly processes only. Circuit performance and electrical characteristics remain unchanged.

Q: Is the P5106UALRP suitable for applications requiring RoHS compliance?

A: Yes. The P5106UALRP is ROHS3 compliant, making it suitable for applications with regulatory compliance requirements. The P5106UARP is not RoHS compliant.

Q: Are there any compatibility concerns when substituting the P5106UALRP for the P5106UARP?

A: No compatibility concerns exist. The components are pin-compatible, functionally equivalent, and share the same Modified MS-013 package specification. Direct substitution is supported without circuit modifications.
