P2000SCMCLRP Equivalent & Substitute Parts

Part Overview

The P2000SCMCLRP is a 180V off-state TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This surface-mount component in DO-214AA (SMB) package is designed for transient voltage suppression applications requiring 400A peak pulse current capability at 8/20µs waveform. The part is active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained within the specified parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2000SCMCLRP is determined by the following critical parameters:

• Voltage - Off State: Must be 180V
• Package / Case: Must be DO-214AA, SMB
• Mounting Type: Must be Surface Mount
• RoHS Status: Must be ROHS3 Compliant

The P2000SCMCLRP has two identified substitute parts. The P2000SCLRP is a direct Littelfuse equivalent with identical voltage ratings, current specifications, and package configuration. The SMTPA180 is a manufacturer-recommended alternative from STMicroelectronics that maintains the same off-state voltage and package type but operates at reduced peak pulse current levels.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full RoHS3 compliance with unlimited moisture sensitivity rating. The P2000SCLRP provides direct electrical and mechanical equivalence to the P2000SCMCLRP, differing only in capacitance specification (35pF versus 50pF). The SMTPA180 from STMicroelectronics is suitable for applications where peak pulse current requirements do not exceed 150A at 8/20µs waveform, with a slightly elevated breakover voltage of 240V. Selection between these parts depends on specific circuit current demands and voltage tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can P2000SCLRP be used as a direct replacement for P2000SCMCLRP?

A: Yes. Both parts are manufactured by Littelfuse Inc. in the SIDACtor® series with identical voltage ratings (180V off-state, 220V breakover), current specifications (400A peak pulse at 8/20µs), and DO-214AA SMB package configuration. The capacitance difference (35pF versus 50pF) reflects manufacturing variation within the same product line.

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

A: The SMTPA180 operates at reduced peak pulse current (150A at 8/20µs versus 400A) and reduced peak pulse current at 10/1000µs waveform (50A versus 100A). It is suitable only for applications where these lower current ratings are acceptable. The breakover voltage is 240V, which is 20V higher than the P2000SCMCLRP.

Q: Are all substitute parts in the same package?

A: Yes. All three parts use the DO-214AA (SMB) surface-mount package, ensuring mechanical compatibility in PCB layouts.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1).
