P2000SCMC Equivalent & Substitute Parts

Part Overview

The P2000SCMC 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's primary function is transient voltage suppression in electronic circuits requiring high peak pulse current handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2000SCMC is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Off State: 180V (primary voltage rating)
• Voltage - Breakover: 220V to 240V (acceptable range for transient suppression)
• Current - Peak Pulse (8/20µs): 150A minimum (application-dependent tolerance)
• Package / Case: DO-214AA, SMB (mechanical compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)

Two substitute parts meet these criteria with varying compliance and availability status.

Engineering Selection Recommendations

P2000SCMCLRP (Direct Littelfuse Substitute)

The P2000SCMCLRP is the primary substitute for the obsolete P2000SCMC. Both parts are manufactured by Littelfuse Inc. within the SIDACtor® series and share identical electrical specifications: 180V off-state voltage, 220V breakover voltage, 400A peak pulse current (8/20µs), and 50pF capacitance. The P2000SCMCLRP is active in production with ROHS3 compliance and higher inventory availability (1282 pcs). The only difference is packaging format: P2000SCMCLRP is supplied in Tape & Reel (TR) configuration versus the original part's unspecified packaging. This substitute provides direct functional equivalence with improved compliance status.

SMTPA180 (STMicroelectronics Alternative)

The SMTPA180 is a manufacturer-recommended alternative from STMicroelectronics in the SMP, TRISIL™ series. It maintains the same 180V off-state voltage and DO-214AA package but differs in peak pulse current ratings: 150A (8/20µs) and 50A (10/1000µs) compared to the original 400A and 100A specifications. The SMTPA180 also features a higher hold current (150mA vs. 120mA) and lower capacitance (25pF vs. 50pF). This part is suitable only for applications where the reduced current handling capacity is acceptable. SMTPA180 is active in production with ROHS3 compliance and the highest inventory availability (3810 pcs).

Frequently Asked Questions (FAQ)

Q: Can P2000SCMCLRP be used as a direct replacement for P2000SCMC?

A: Yes. The P2000SCMCLRP is electrically and mechanically identical to the P2000SCMC. Both parts have 180V off-state voltage, 220V breakover voltage, 400A peak pulse current (8/20µs), and identical on-state voltage and hold current specifications. The only difference is packaging format (Tape & Reel vs. unspecified). For surface mount assembly, this substitution is direct.

Q: When is SMTPA180 appropriate as a substitute?

A: SMTPA180 is appropriate only when the application can tolerate reduced peak pulse current handling. The SMTPA180 is rated for 150A (8/20µs) and 50A (10/1000µs), compared to the original 400A and 100A. If the circuit design requires the full 400A peak pulse current capacity, SMTPA180 is not suitable. Verify application transient current requirements before selecting this alternative.

Q: What is the difference between P2000SCMC and P2000SCMCLRP packaging?

A: P2000SCMC product status is listed as obsolete with unspecified packaging. P2000SCMCLRP is the active production equivalent supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Both parts use the DO-214AA (SMB) case style and are compatible with the same PCB footprint.

Q: Are all substitute parts RoHS compliant?

A: P2000SCMC is RoHS non-compliant. Both P2000SCMCLRP and SMTPA180 are ROHS3 compliant. If RoHS compliance is required for new designs or procurement, select either P2000SCMCLRP or SMTPA180.

Q: Which substitute has the best inventory availability?

A: SMTPA180 has the highest inventory availability at 3810 pcs. P2000SCMCLRP has 1282 pcs available. However, inventory levels are subject to change and should be verified at the time of procurement.
