P2300SCMC Equivalent & Substitute Parts

Part Overview

The P2300SCMC is a 190V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part's electrical characteristics—specifically its 260V breakover voltage, 5V on-state voltage, and 150mA hold current—define the functional requirements for suitable alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2300SCMC is determined by electrical parameter compatibility within the transient voltage suppressor category. The critical parameters governing substitution are:

• Voltage - Off State (190V nominal)
• Voltage - Breakover (260V nominal)
• Current - Peak Pulse (8/20µs) rating (400A nominal)
• Current - Hold (Ih) (150mA nominal)
• Package / Case (DO-214AA, SMB surface mount)
• Number of Elements (single element configuration)

Two substitute parts are identified: P2300SCMCLRP (direct equivalent from Littelfuse Inc.) and SMP100MC-200 (manufacturer-recommended alternative from STMicroelectronics). The P2300SCMCLRP maintains identical electrical specifications with packaging variation (Tape & Reel). The SMP100MC-200 represents a functional alternative with specified parameter deviations within the TVS thyristor category.

Parameter Comparison

Engineering Selection Recommendations

P2300SCMCLRP is the direct functional equivalent of P2300SCMC, maintaining identical electrical specifications across all measured parameters. This part is currently in active production status with ROHS3 compliance certification, addressing the obsolescence of the original P2300SCMC. The only distinction is packaging format (Tape & Reel versus bulk), which does not affect electrical performance.

SMP100MC-200 is a manufacturer-recommended alternative from STMicroelectronics. This part operates at a 200V off-state voltage (10V higher than the original), with a reduced peak pulse current rating of 300A (8/20µs) compared to the original 400A specification. The breakover voltage is 250V (10V lower than the original). This part maintains the same hold current (150mA), package format (DO-214AA, SMB), and single-element configuration. SMP100MC-200 is suitable for applications where the specified parameter deviations are acceptable within circuit design margins. Both substitute parts carry ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can P2300SCMCLRP be used as a direct replacement for P2300SCMC?

A: Yes. P2300SCMCLRP is electrically identical to P2300SCMC across all specified parameters. The difference is packaging format (Tape & Reel versus bulk). Both parts are housed in DO-214AA (SMB) surface mount packages with identical pin configurations and electrical performance.

Q: What are the key differences between P2300SCMC and SMP100MC-200?

A: The SMP100MC-200 differs in three electrical parameters: off-state voltage (200V versus 190V), breakover voltage (250V versus 260V), and peak pulse current rating (300A versus 400A at 8/20µs). The hold current, on-state voltage, and package format remain compatible. Circuit design verification is required to confirm acceptability of these deviations.

Q: Why is P2300SCMC listed as obsolete?

A: The P2300SCMC is classified as obsolete by the manufacturer. P2300SCMCLRP is the active production equivalent and is recommended for new designs and procurement.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both P2300SCMCLRP and SMP100MC-200 are ROHS3 compliant. The original P2300SCMC is RoHS non-compliant.

Q: Can SMP100MC-200 be used in all applications where P2300SCMC is specified?

A: SMP100MC-200 is suitable only for applications where the specified parameter deviations (10V higher off-state voltage, 10V lower breakover voltage, and 100A lower peak pulse current at 8/20µs) fall within acceptable design margins. Circuit-level verification is required.

Q: What is the difference in capacitance between these parts?

A: P2300SCMC and P2300SCMCLRP both have 50pF capacitance. SMP100MC-200 has 45pF capacitance, a 5pF reduction that may affect high-frequency transient response characteristics.
