P2106UBRP Equivalent & Substitute Parts

Part Overview

The P2106UBRP is a 170V off-state, 250A peak pulse TVS thyristor manufactured by Littelfuse in a 6-SMD gull wing surface mount package. This component is classified as a SIDACtor® transient voltage suppressor designed for overvoltage protection applications. The part is currently obsolete, making identification of compatible substitutes necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2106UBRP is determined by electrical and mechanical parameter equivalence. The critical parameters for substitution are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current ratings (both 8/20µs and 10/1000µs)
• Hold current specification
• Number of elements and capacitance values
• Package type and mounting configuration

The P2106UBLRP meets all these criteria as a direct substitute, with identical electrical specifications and package configuration. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P2106UBLRP is a direct electrical and mechanical equivalent to the P2106UBRP. Selection between these parts should be based on the following factors:

For new designs or systems requiring regulatory compliance, the P2106UBLRP is the appropriate choice due to its active product status and ROHS3 compliance certification. This part maintains identical electrical performance while offering improved environmental compliance.

For legacy system support where the original P2106UBRP is specified, the P2106UBLRP provides functional equivalence with no circuit redesign required. The packaging format difference (tape & reel versus bulk) affects procurement and assembly processes but does not impact electrical performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can P2106UBLRP be used as a direct replacement for P2106UBRP in existing designs?

A: Yes. The P2106UBLRP is electrically and mechanically identical to the P2106UBRP. All voltage ratings, current specifications, and package dimensions are equivalent. No circuit modifications are required.

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

A: The primary differences are product status and packaging format. The P2106UBRP is obsolete and supplied in bulk packaging, while the P2106UBLRP is an active product supplied in tape & reel format. The P2106UBLRP also carries ROHS3 compliance certification.

Q: Are there any compatibility concerns with the 6-SMD gull wing package?

A: No. Both parts use the identical 6-SMD gull wing surface mount package with the same footprint and mounting requirements. PCB layout and assembly processes remain unchanged.

Q: Does the tape & reel packaging of P2106UBLRP affect circuit performance?

A: No. Packaging format is a procurement and assembly consideration only. Electrical performance and functional characteristics are identical regardless of packaging format.

Q: Is the P2106UBLRP suitable for applications requiring RoHS compliance?

A: Yes. The P2106UBLRP is ROHS3 compliant, making it suitable for applications with environmental and regulatory compliance requirements.
