P2500SCLRP Equivalent & Substitute Parts

Part Overview

The P2500SCLRP is a 230V off-state thyristor transient voltage suppressor 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. The part is active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating. 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

Substitution eligibility for the P2500SCLRP is determined by the following critical parameters:

• Voltage - Off State: 230V (exact match required)
• Voltage - Breakover: 290V ±5V tolerance 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: P2500SCMCLRP (Littelfuse Inc., direct manufacturer variant) and SMP100LC-230 (STMicroelectronics, manufacturer-recommended alternative). Both maintain identical off-state voltage, peak pulse current ratings, and package specifications. Variations in capacitance and hold current are within acceptable ranges for transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—P2500SCLRP, P2500SCMCLRP, and SMP100LC-230—are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and packaging format:

P2500SCLRP and P2500SCMCLRP are both Littelfuse SIDACtor® devices with identical electrical specifications and are interchangeable at the circuit level. The primary difference is capacitance (85pF vs. 45pF), which may influence high-frequency circuit behavior but does not affect core transient suppression function.

SMP100LC-230 is the STMicroelectronics TRISIL™ equivalent with a 5V lower breakover voltage (285V vs. 290V) and 30mA higher hold current (150mA vs. 120mA). These variations remain within acceptable operating margins for transient voltage suppression applications. SMP100LC-230 is supplied in Cut Tape and Digi-Reel® packaging, whereas P2500SCLRP and P2500SCMCLRP are supplied in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can P2500SCMCLRP be used as a direct replacement for P2500SCLRP?

A: Yes. Both parts are manufactured by Littelfuse Inc., share identical voltage and current ratings, and use the same DO-214AA SMB package. The capacitance difference (45pF vs. 85pF) does not affect transient suppression performance in standard applications.

Q: What is the significance of the 5V breakover voltage difference between P2500SCLRP (290V) and SMP100LC-230 (285V)?

A: The 5V difference represents a 1.7% variation within acceptable engineering tolerance for transient voltage suppressors. Both parts maintain the same 230V off-state voltage specification and will function equivalently in circuit protection applications.

Q: Does the 30mA difference in hold current (120mA vs. 150mA) affect circuit compatibility?

A: No. Both hold current values are well above typical circuit requirements for transient suppression. The difference does not impact device switching behavior or circuit performance in standard applications.

Q: Are there packaging format differences between these parts?

A: Yes. P2500SCLRP and P2500SCMCLRP are supplied in Tape & Reel (TR) format. SMP100LC-230 is supplied in Cut Tape (CT) and Digi-Reel® format. All three use the same DO-214AA SMB surface-mount package.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. They are suitable for equivalent use in regulated applications.

Q: Which part should be selected for new designs?

A: Selection depends on supply availability and packaging preference. For Littelfuse-specified designs, either P2500SCLRP or P2500SCMCLRP is appropriate. For multi-source designs, SMP100LC-230 provides equivalent performance with broader supplier availability.
