Equivalent & Substitute Parts for P2500SC

Part Overview

The P2500SC 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 suitable alternatives necessary for ongoing design support and procurement continuity. The part provides transient voltage suppression for applications requiring high current handling at specified voltage thresholds.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2500SC is determined by the following critical parameters:

• Voltage - Off State: 230V (exact match required)
• Voltage - Breakover: within acceptable tolerance range
• Current - Peak Pulse (8/20µs): 400A (exact match required)
• Package / Case: DO-214AA, SMB (mechanical and electrical compatibility)
• Number of Elements: 1 (functional equivalence)

The substitute parts P2500SCLRP and SMP100LC-230 meet these core electrical and mechanical requirements, enabling direct functional replacement in circuit applications designed for the P2500SC.

Parameter Comparison

Engineering Selection Recommendations

P2500SCLRP is the direct functional equivalent to P2500SC, manufactured by Littelfuse Inc. with identical electrical specifications and packaging. This part is active in production status and ROHS3 compliant, providing regulatory advantage over the obsolete P2500SC. The primary distinction is packaging format: P2500SCLRP is supplied in Tape & Reel configuration versus the P2500SC's standard packaging.

SMP100LC-230, manufactured by STMicroelectronics, meets the core electrical requirements with minor parameter variations. The breakover voltage is 285V (versus 290V), hold current is 150mA (versus 120mA), and capacitance is 60pF (versus 85pF). This part is active in production and ROHS3 compliant. The SMP100LC-230 is supplied in Cut Tape and Digi-Reel® packaging formats.

Both substitute parts satisfy the mandatory electrical parameters for 230V off-state operation and 400A peak pulse current handling in the DO-214AA SMB package. Selection between P2500SCLRP and SMP100LC-230 depends on packaging availability, supply chain considerations, and application tolerance for the specified parameter variations.

Frequently Asked Questions (FAQ)

Q: Can P2500SCLRP directly replace P2500SC in existing designs?

A: Yes. P2500SCLRP is electrically and mechanically identical to P2500SC, with identical voltage ratings, current ratings, and DO-214AA SMB packaging. The primary difference is packaging format (Tape & Reel versus standard packaging).

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

A: Both parts share the same 230V off-state voltage, 400A peak pulse current, and DO-214AA SMB package. Differences include: breakover voltage (290V vs. 285V), hold current (120mA vs. 150mA), and capacitance (85pF vs. 60pF). SMP100LC-230 is manufactured by STMicroelectronics rather than Littelfuse Inc.

Q: Are all substitute parts RoHS compliant?

A: P2500SCLRP and SMP100LC-230 are both ROHS3 compliant. The original P2500SC is RoHS non-compliant.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (P2500SCLRP) and Cut Tape with Digi-Reel® (SMP100LC-230) packaging formats do not affect electrical performance. Packaging selection is determined by assembly equipment compatibility and procurement requirements.

Q: Which substitute part should be selected for new designs?

A: Selection should be based on component availability, supply chain reliability, and application tolerance for parameter variations. Both P2500SCLRP and SMP100LC-230 meet the core electrical requirements for 230V TVS thyristor applications in the DO-214AA SMB package.
