P2000SCRP Equivalent & Substitute Parts

Part Overview

The P2000SCRP is a 180V off-state, 400A 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, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The part provides transient voltage suppression through thyristor-based clamping action suitable for applications requiring high peak current handling in compact form factors.

Substitute Part Grouping Explanation

Substitution for the P2000SCRP is determined by the following critical parameters: off-state voltage (180V), package type (DO-214AA/SMB), mounting configuration (surface mount), and functional category (TVS thyristor). Substitute parts must maintain electrical compatibility within the specified voltage and current ratings while preserving the same physical form factor.

Two substitution categories are identified:

Direct Manufacturer Substitutes (Littelfuse): Parts maintaining identical electrical specifications and packaging from the original manufacturer, differing only in product status or packaging format.

Cross-Manufacturer Equivalent (STMicroelectronics): Parts meeting the core voltage and package requirements but with variations in peak current ratings and hold current specifications.

Parameter Comparison

Engineering Selection Recommendations

P2000SCLRP (Littelfuse Inc.): This part is the direct functional equivalent of the P2000SCRP, maintaining identical electrical specifications and package configuration. The primary distinction is product status—P2000SCLRP is active and available in Tape & Reel packaging format. This part is ROHS3 compliant and represents the recommended path for designs currently using the obsolete P2000SCRP. Procurement availability is significantly higher (1988 pcs in stock versus 942 pcs for the original part).

SMTPA180 (STMicroelectronics): This cross-manufacturer substitute operates at the same 180V off-state voltage and uses identical DO-214AA/SMB packaging. However, peak pulse current ratings are reduced (150A versus 400A at 8/20µs, and 50A versus 100A at 10/1000µs). The hold current is higher at 150mA compared to 120mA. This part is suitable only for applications where the lower current ratings are acceptable. SMTPA180 is ROHS3 compliant and actively manufactured.

Selection between P2000SCLRP and SMTPA180 depends on circuit current requirements. For designs requiring the full 400A peak pulse capability, P2000SCLRP is the only viable substitute. For lower-current applications, SMTPA180 provides an alternative from a different manufacturer.

Frequently Asked Questions (FAQ)

Q: Can P2000SCLRP be used as a direct replacement for P2000SCRP?

A: Yes. P2000SCLRP maintains identical electrical specifications (180V off-state, 220V breakover, 400A peak pulse at 8/20µs, 120mA hold current) and package configuration (DO-214AA/SMB surface mount). The parts are functionally equivalent. P2000SCLRP is active and available, whereas P2000SCRP is obsolete.

Q: What are the limitations of using SMTPA180 as a substitute?

A: SMTPA180 has reduced peak pulse current ratings: 150A at 8/20µs (versus 400A) and 50A at 10/1000µs (versus 100A). Hold current is higher at 150mA. These differences make SMTPA180 unsuitable for applications requiring the full current-handling capability of the original part. Verify that circuit transient energy levels are compatible with the lower current ratings before selection.

Q: Are all substitute parts RoHS compliant?

A: P2000SCRP is RoHS non-compliant. Both P2000SCLRP and SMTPA180 are ROHS3 compliant. If RoHS compliance is a design requirement, the original part cannot be used; substitution is mandatory.

Q: Do all parts use the same package?

A: Yes. P2000SCRP, P2000SCLRP, and SMTPA180 all use DO-214AA (SMB) surface mount packaging. PCB layout and footprints are compatible across all three parts.

Q: What is the difference between P2000SCRP and P2000SCLRP packaging?

A: P2000SCRP is supplied in standard packaging format. P2000SCLRP is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly. Electrical specifications are identical.

Q: Can SMTPA180 be used in all applications where P2000SCRP is specified?

A: No. SMTPA180 is suitable only for applications where peak pulse current requirements do not exceed 150A at 8/20µs. For circuits designed around the 400A capability of P2000SCRP, SMTPA180 will not provide adequate transient suppression. Circuit analysis is required to determine compatibility.
