Equivalent & Substitute Parts for P2500SCRP

Part Overview

The P2500SCRP is a 230V off-state, 400A peak pulse thyristor TVS device manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA SMB package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The part operates with a 290V breakover voltage and 4V on-state voltage, designed for transient voltage suppression applications requiring high current handling capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2500SCRP is determined by the following critical parameters:

• Voltage - Off State: 230V (exact match required)
• Voltage - Breakover: 290V nominal (tolerance range acceptable)
• Current - Peak Pulse (8/20µs): 400A (exact match required)
• Current - Peak Pulse (10/1000µs): 100A (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Number of Elements: 1 (exact match required)

Two substitute parts meet these criteria: P2500SCLRP (direct Littelfuse equivalent with identical electrical specifications and active product status) and SMP100LC-230 (STMicroelectronics TRISIL™ series alternative with equivalent electrical performance and active availability).

Parameter Comparison

Engineering Selection Recommendations

P2500SCLRP is the direct functional equivalent, manufactured by Littelfuse Inc. in the same SIDACtor® series with identical electrical specifications. This part carries active product status and ROHS3 compliance, addressing the obsolescence of the original P2500SCRP. Packaging is available in Tape & Reel format with substantially higher inventory availability (2100 units).

SMP100LC-230 is a cross-manufacturer alternative from STMicroelectronics in the TRISIL™ series. It meets all critical electrical requirements with a 285V breakover voltage (5V lower than the P2500SCRP nominal), 400A peak pulse current, and equivalent 100A secondary pulse rating. The SMP100LC-230 exhibits a higher hold current (150mA versus 120mA) and lower capacitance (60pF versus 85pF). This part maintains active product status, ROHS3 compliance, and exceptional inventory depth (187700 units). Packaging is available in Cut Tape and Digi-Reel® formats.

Both substitutes are suitable for applications where the P2500SCRP is specified, provided circuit design tolerates the noted parameter variations.

Frequently Asked Questions (FAQ)

Q: Can P2500SCLRP directly replace P2500SCRP without circuit modification?

A: Yes. P2500SCLRP is electrically identical to P2500SCRP across all critical parameters: 230V off-state voltage, 290V breakover, 400A peak pulse current, and DO-214AA SMB package. The primary difference is product status (active versus obsolete) and packaging format (Tape & Reel availability).

Q: What are the key differences between P2500SCLRP and SMP100LC-230?

A: Both parts share identical off-state voltage (230V), peak pulse current ratings (400A and 100A), and package format (DO-214AA SMB). SMP100LC-230 has a 5V lower breakover voltage (285V versus 290V), 30mA higher hold current (150mA versus 120mA), and 25pF lower capacitance (60pF versus 85pF). These differences are within acceptable substitution tolerances for most transient voltage suppression applications.

Q: Does the lower breakover voltage of SMP100LC-230 affect circuit performance?

A: The 5V difference (285V versus 290V) represents a 1.7% deviation. For applications with tight voltage tolerance requirements, this variation must be evaluated against circuit specifications. For general transient suppression applications, this difference is typically acceptable.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both P2500SCLRP and SMP100LC-230 carry ROHS3 compliance certification. The original P2500SCRP is RoHS non-compliant, making either substitute suitable for RoHS-regulated applications.

Q: Which substitute offers better availability?

A: SMP100LC-230 provides significantly higher inventory (187700 units) compared to P2500SCLRP (2100 units), making it the preferred choice for high-volume procurement or long-term supply assurance.

Q: Can I use SMP100LC-230 in existing designs specified for P2500SCRP?

A: Yes, provided circuit design accommodates the noted parameter variations: 5V lower breakover voltage, 30mA higher hold current, and 25pF lower capacitance. Verification against application-specific requirements is necessary.
