P2103UBRP Equivalent & Substitute Parts

Part Overview

The P2103UBRP is a Transient Voltage Suppressor (TVS) thyristor from Littelfuse Inc.'s SIDACtor® series, designed for overvoltage protection in surface mount applications. This component features a 170V off-state voltage rating with 250A peak pulse current capability in a 6-SMD gull wing package. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2103UBRP is determined by strict equivalence across the following critical parameters:

• Voltage ratings: Breakover voltage (250V), off-state voltage (170V), and on-state voltage (8V) must match exactly
• Current specifications: Peak pulse current at 8/20µs (250A) and 10/1000µs (80A) must be identical
• Hold current (Ih): 150mA requirement must be maintained
• Element count: 3-element configuration required
• Capacitance range: 55pF to 85pF specification must be preserved
• Package configuration: 6-SMD gull wing surface mount form factor is mandatory
• Electrical characteristics must remain within the Modified MS-013 supplier device package specification

The P2103UBLRP meets all substitution criteria as a direct electrical and mechanical equivalent, with the primary distinction being packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P2103UBLRP is the direct substitute for the obsolete P2103UBRP. All electrical and mechanical parameters are identical, ensuring functional equivalence in circuit applications. The P2103UBLRP offers three significant advantages:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance satisfies current environmental and regulatory requirements
• Tape & Reel packaging format supports automated assembly processes for production environments

For applications requiring bulk component format, the P2103UBRP may be sourced from existing inventory. For new designs and production applications, the P2103UBLRP is the appropriate selection due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can P2103UBLRP be used as a direct replacement for P2103UBRP in existing designs?

A: Yes. The P2103UBLRP is electrically and mechanically identical to the P2103UBRP across all specified parameters, including voltage ratings, current ratings, element count, capacitance, and package configuration. No circuit modifications are required.

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

A: Bulk packaging (P2103UBRP) is suitable for manual assembly and small-quantity applications. Tape & Reel packaging (P2103UBLRP) is designed for automated pick-and-place assembly processes used in high-volume production environments.

Q: Why is RoHS compliance status different between these parts?

A: The P2103UBRP is classified as RoHS non-compliant due to its obsolete status. The P2103UBLRP, as an active product, meets ROHS3 compliance standards, making it suitable for applications subject to environmental and regulatory requirements.

Q: Are there any electrical performance differences between these substitutes?

A: No. Both parts maintain identical electrical characteristics: 250V breakover voltage, 170V off-state voltage, 8V on-state voltage, 250A peak pulse current (8/20µs), 80mA peak pulse current (10/1000µs), and 150mA hold current.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Both parts use the same 6-SMD gull wing surface mount package and Modified MS-013 supplier device package specification, allowing direct PCB footprint compatibility.
