CR2300SC Equivalent & Substitute Parts

Part Overview

The CR2300SC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in surface-mount applications. This component features a 190V off-state voltage rating with 250A peak pulse current capability in a DO-214AA (SMB) package. The CR2300SC is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CR2300SC is determined by the following critical electrical and mechanical parameters:

• Voltage Ratings: Breakover voltage (260V), off-state voltage (190V), and on-state voltage must remain within acceptable tolerance for the protection circuit.
• Current Ratings: Peak pulse current capability (8/20µs and 10/1000µs waveforms) and hold current must meet or exceed the original specification.
• Package Compatibility: Surface-mount DO-214AA (SMB) package is mandatory for PCB layout compatibility.
• Number of Elements: Single-element configuration required.

The P2300SCLRP qualifies as a direct substitute based on matching voltage ratings, identical package type, and superior current handling capability.

Parameter Comparison

Engineering Selection Recommendations

The P2300SCLRP is the qualified substitute for the CR2300SC based on the following criteria:

• Electrical Compatibility: Identical voltage ratings (260V breakover, 190V off-state) ensure equivalent circuit protection performance. The P2300SCLRP delivers 400A peak pulse current (8/20µs), exceeding the original 250A specification, providing enhanced transient suppression capability.
• Package Compatibility: Both components use the DO-214AA (SMB) surface-mount package, enabling direct PCB layout compatibility without redesign.
• Product Status: The P2300SCLRP is active and in production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The P2300SCLRP is ROHS3 compliant, meeting current environmental and regulatory requirements, whereas the CR2300SC is non-compliant.
• Series Designation: The P2300SCLRP belongs to the SIDACtor® series, representing current-generation technology from Littelfuse Inc.

Frequently Asked Questions (FAQ)

Q: Can the P2300SCLRP directly replace the CR2300SC without circuit modification?

A: Yes. Both components share identical voltage ratings (260V breakover, 190V off-state), matching hold current (150mA), and the same DO-214AA package. The P2300SCLRP's higher peak pulse current (400A vs. 250A) is a performance enhancement that does not require circuit changes.

Q: What is the difference in on-state voltage between the two parts?

A: The CR2300SC has a 5V on-state voltage, while the P2300SCLRP has a 4V on-state voltage. This 1V difference is within typical operating margins for TVS thyristor applications and does not affect substitution compatibility.

Q: Does the increased capacitance of the P2300SCLRP (80pF vs. 60pF) affect circuit performance?

A: The capacitance difference is 20pF, which is negligible in most protection circuits. This parameter should be evaluated only if the application involves high-frequency signal integrity requirements or impedance-sensitive circuits.

Q: Is the P2300SCLRP available in the same packaging format?

A: Yes. The P2300SCLRP is supplied in Tape & Reel (TR) packaging, which is the standard format for surface-mount production. The component itself uses the identical DO-214AA (SMB) package.

Q: What is the regulatory advantage of using the P2300SCLRP?

A: The P2300SCLRP is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The CR2300SC is RoHS non-compliant, making the P2300SCLRP the appropriate choice for applications requiring regulatory compliance.
