P2500SCMC Equivalent & Substitute Parts

Part Overview

The P2500SCMC is a 230V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA SMB 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 surface-mount applications requiring high current handling capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2500SCMC is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Off State: 230V (primary voltage rating)
• Voltage - Breakover: 285V–290V (acceptable range for transient suppression)
• Current - Peak Pulse (8/20µs): 400A (primary current rating)
• Current - Hold (Ih): 120mA–150mA (acceptable range for holding current)
• Package / Case: DO-214AA, SMB (mechanical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)

Two substitute parts meet these criteria: P2500SCMCLRP (direct Littelfuse equivalent with active product status) and SMP100LC-230 (STMicroelectronics TRISIL™ alternative with manufacturer recommendation).

Parameter Comparison

Engineering Selection Recommendations

P2500SCMCLRP is the primary substitute for P2500SCMC. Both parts are manufactured by Littelfuse Inc. within the SIDACtor® series and share identical electrical specifications. P2500SCMCLRP carries active product status and ROHS3 compliance, addressing the obsolescence and regulatory limitations of the original part. The only difference is packaging format: P2500SCMCLRP is supplied in Tape & Reel (TR) configuration versus the original part's unspecified packaging.

SMP100LC-230 is an alternative substitute manufactured by STMicroelectronics. It meets all critical electrical parameters with minor variations: breakover voltage of 285V (within acceptable tolerance of the 290V specification), holding current of 150mA (within acceptable tolerance of the 120mA specification), and capacitance of 60pF (versus 45pF). SMP100LC-230 is ROHS3 compliant and carries active product status. This part is suitable where STMicroelectronics supply chain or inventory availability is preferred.

Frequently Asked Questions (FAQ)

Q: Can P2500SCMCLRP be used as a direct replacement for P2500SCMC?

A: Yes. P2500SCMCLRP is electrically and mechanically identical to P2500SCMC. Both parts share the same voltage ratings (230V off-state, 290V breakover), current ratings (400A peak pulse at 8/20µs), and DO-214AA SMB package. The primary advantage of P2500SCMCLRP is active product status and ROHS3 compliance.

Q: What are the differences between P2500SCMCLRP and SMP100LC-230?

A: Both parts meet the core electrical requirements for 230V off-state, 400A peak pulse TVS thyristor applications. SMP100LC-230 has a breakover voltage of 285V (versus 290V) and holding current of 150mA (versus 120mA). Capacitance differs at 60pF versus 45pF. These variations remain within acceptable operating ranges for transient suppression. The primary difference is manufacturer: Littelfuse versus STMicroelectronics.

Q: Are there packaging differences between these substitutes?

A: All three parts use the DO-214AA SMB package for surface-mount assembly. P2500SCMCLRP is supplied in Tape & Reel (TR) format, while SMP100LC-230 is supplied in Cut Tape (CT) and Digi-Reel® format. Both packaging formats are compatible with standard pick-and-place assembly equipment.

Q: Why is the original P2500SCMC obsolete?

A: The P2500SCMC is classified as obsolete by Littelfuse Inc. Substitute parts P2500SCMCLRP and SMP100LC-230 provide equivalent or superior functionality with active product status and modern compliance certifications (ROHS3).

Q: Which substitute should I select for new designs?

A: Selection depends on supply chain requirements and compliance needs. P2500SCMCLRP is recommended for direct replacement due to identical specifications and Littelfuse continuity. SMP100LC-230 is suitable where STMicroelectronics supply or inventory is preferred, provided the minor parameter variations (285V breakover, 150mA holding current, 60pF capacitance) are acceptable for the application.
