P3100SDRP Equivalent & Substitute Parts

Part Overview

The P3100SDRP is a 275V off-state, 1 kA peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

The P3100SDLRP qualifies as a direct substitute for the P3100SDRP based on the following criteria:

• Identical voltage ratings: 350V breakover, 275V off-state, 4V on-state
• Identical current specifications: 1 kA peak pulse (8/20µs), 200 A peak pulse (10/1000µs), 50 mA hold current
• Identical capacitance: 70 pF
• Identical package and mounting: DO-214AA (SMB) surface mount
• Identical number of elements: 1
• Same manufacturer: Littelfuse Inc.
• Same series: SIDACtor®

The only differences are packaging format (Tape & Reel vs. standard packaging) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P3100SDLRP is the direct equivalent for the obsolete P3100SDRP. Selection of the P3100SDLRP is supported by:

• Active product status ensuring ongoing availability and manufacturing support
• ROHS3 compliance, meeting current environmental and regulatory requirements
• Identical electrical and mechanical specifications across all critical parameters
• Same manufacturer and series lineage, ensuring design compatibility
• Tape & Reel packaging suitable for automated assembly processes

For applications requiring the P3100SDRP, the P3100SDLRP provides functional and physical interchangeability without design modification.

Frequently Asked Questions (FAQ)

Q: Can the P3100SDLRP be used as a direct replacement for the P3100SDRP?

A: Yes. All electrical parameters, voltage ratings, current ratings, capacitance, and package specifications are identical. The components are functionally interchangeable.

Q: What is the difference between P3100SDRP and P3100SDLRP?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (standard vs. Tape & Reel). Electrical and mechanical specifications are identical.

Q: Is the DO-214AA package the same for both parts?

A: Yes. Both parts use the DO-214AA (SMB) surface mount package with identical pin configuration and footprint.

Q: Does the Tape & Reel packaging of the P3100SDLRP affect compatibility?

A: No. Tape & Reel is a supply format for automated assembly. The component itself is identical and compatible with the same PCB footprint and circuit design.

Q: Are there RoHS compliance implications when switching from P3100SDRP to P3100SDLRP?

A: The P3100SDLRP is ROHS3 compliant, whereas the P3100SDRP is not. For applications subject to RoHS regulations, the P3100SDLRP meets current compliance requirements.
