P2000SCLRP Equivalent & Substitute Parts

Part Overview

The P2000SCLRP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This surface-mount component operates at 180V off-state voltage with a peak pulse current rating of 400A (8/20µs), housed in a DO-214AA (SMB) package. The part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitute parts for the P2000SCLRP are classified based on the following electrical and mechanical criteria:

Direct Manufacturer Substitutes (Littelfuse Inc.): Parts maintaining identical voltage ratings (180V off-state, 220V breakover), current specifications (400A peak pulse at 8/20µs, 100A at 10/1000µs), on-state voltage (4V), and hold current (120mA). These parts are interchangeable within the same package footprint (DO-214AA, SMB) and mounting configuration.

Manufacturer-Recommended Alternatives (Cross-Manufacturer): Parts from alternative manufacturers that maintain the core voltage and package specifications but may vary in peak pulse current ratings and hold current parameters. These are suitable when primary supply sources are unavailable.

Parameter Comparison

Engineering Selection Recommendations

P2000SCMCLRP (Littelfuse Inc.): This direct substitute maintains all critical electrical parameters identical to the P2000SCLRP, including voltage ratings, peak pulse current (400A at 8/20µs), and hold current (120mA). The only variance is capacitance (50pF versus 35pF), which does not affect substitution eligibility. Both parts are Active status, ROHS3 compliant, and housed in identical DO-214AA, SMB packages. This part is the primary equivalent choice.

SMTPA180 (STMicroelectronics): This manufacturer-recommended alternative operates at the same 180V off-state voltage and DO-214AA, SMB package configuration. However, peak pulse current is reduced to 150A (8/20µs) and 50A (10/1000µs), with increased hold current (150mA). The breakover voltage is 240V versus 220V. This part is suitable only for applications where the reduced current ratings and higher breakover voltage are acceptable. Both parts maintain ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can P2000SCMCLRP be used as a direct replacement for P2000SCLRP? A: Yes. Both parts are manufactured by Littelfuse Inc., operate at identical voltage ratings (180V off-state, 220V breakover), and deliver the same peak pulse current (400A at 8/20µs) and hold current (120mA). The capacitance difference (50pF versus 35pF) does not prevent substitution. Both are housed in DO-214AA, SMB packages and are ROHS3 compliant.

Q: When is SMTPA180 an appropriate substitute? A: SMTPA180 is suitable when the application can tolerate reduced peak pulse current (150A versus 400A at 8/20µs) and increased hold current (150mA versus 120mA). The higher breakover voltage (240V versus 220V) must also be compatible with circuit requirements. This part is recommended only when primary Littelfuse options are unavailable.

Q: Are all substitute parts in the same package? A: Yes. P2000SCLRP, P2000SCMCLRP, and SMTPA180 are all housed in DO-214AA (SMB) packages with surface-mount configuration, ensuring mechanical and footprint compatibility.

Q: What compliance certifications apply to all listed parts? A: All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. All are classified under ECCN EAR99 and HTSUS 8541.30.0080.

Q: How do voltage ratings affect substitution? A: Off-state voltage (180V) and on-state voltage (4V) must remain constant for direct substitution. Breakover voltage variance (220V versus 240V) requires circuit-level evaluation to confirm compatibility with transient suppression requirements.
