P2100SCMCLRP Equivalent & Substitute Parts

Part Overview

The P2100SCMCLRP 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 and in production with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2100SCMCLRP is determined by the following critical parameters:

• Voltage - Off State: 180V (exact match required)
• Voltage - Breakover: 240V (exact match required)
• Current - Hold (Ih): 150mA (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)

Substitute parts must maintain identical off-state voltage, breakover voltage, hold current, and package configuration. Variations in peak pulse current capability, on-state voltage, and capacitance are permissible within the constraints of the application circuit design. All substitutes must maintain active product status and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

P2100SCLRP is a direct substitute for P2100SCMCLRP. Both parts are manufactured by Littelfuse Inc., share identical electrical specifications for voltage and hold current parameters, and are packaged in DO-214AA (SMB) configuration. The primary difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) and inventory availability. Both maintain active product status and ROHS3 compliance.

SMTPA180 is a manufacturer-recommended alternative from STMicroelectronics. This part maintains the critical voltage parameters (180V off-state, 240V breakover) and hold current (150mA) required for functional compatibility. The SMTPA180 operates at reduced peak pulse current ratings (150A at 8/20µs versus 400A), making it suitable for applications where lower transient current suppression is acceptable. All three parts maintain ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can P2100SCLRP replace P2100SCMCLRP in all applications?

A: Yes. P2100SCLRP is a direct substitute with identical electrical specifications. The difference is packaging format and supplier reel configuration. Both are Littelfuse SIDACtor® devices with matching voltage ratings and current handling characteristics.

Q: What is the primary limitation of SMTPA180 as a substitute?

A: SMTPA180 has reduced peak pulse current capability (150A at 8/20µs compared to 400A). This part is suitable only for applications where the transient current requirement does not exceed 150A. The voltage parameters and hold current remain equivalent.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the DO-214AA (SMB) package with identical pinout and footprint. Surface mount assembly compatibility is maintained across all substitutes.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. P2100SCMCLRP, P2100SCLRP, and SMTPA180 are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: What packaging options are available?

A: P2100SCMCLRP is supplied in Tape & Reel (TR) format. P2100SCLRP is available in Cut Tape (CT) & Digi-Reel® format. SMTPA180 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly line requirements and volume considerations.
