NP2300SCT3G Equivalent & Substitute Parts

Part Overview

The NP2300SCT3G is a 190V off-state thyristor-based transient voltage suppressor (TVS) in DO-214AA surface mount packaging, manufactured by onsemi. This component is designed for transient overvoltage protection applications requiring 100A peak pulse current capability at 10/1000µs pulse width. The part is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NP2300SCT3G is determined by the following critical electrical and mechanical parameters:

• Voltage Rating Match: Off-state voltage of 190V and breakover voltage of 260V must be identical
• On-State Voltage: 4V on-state voltage must be maintained
• Hold Current: 150mA hold current specification must be met
• Package Compatibility: DO-214AA, SMB surface mount package is required
• Element Configuration: Single-element design

The P2300SCLRP from Littelfuse Inc. satisfies all these substitution criteria. While it offers enhanced peak pulse current capability (400A at 8/20µs), it maintains full compatibility with the voltage ratings, on-state characteristics, hold current, and package requirements of the original NP2300SCT3G.

Parameter Comparison

Engineering Selection Recommendations

The P2300SCLRP is the direct functional equivalent for NP2300SCT3G applications. Selection between these parts should be based on the following factors:

Product Status: The NP2300SCT3G is obsolete. The P2300SCLRP is active and in production, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: The P2300SCLRP carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Inventory & Procurement: The P2300SCLRP has significantly higher stock availability (44,600 pcs) compared to the NP2300SCT3G (5,600 pcs), supporting immediate procurement needs.

Electrical Performance: The P2300SCLRP maintains all critical voltage and current parameters required for direct substitution. The increased peak pulse current rating at 8/20µs pulse width provides additional margin without affecting core circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the P2300SCLRP directly replace the NP2300SCT3G in existing designs?

A: Yes. The P2300SCLRP meets all critical electrical parameters (190V off-state, 260V breakover, 4V on-state, 150mA hold current) and uses the identical DO-214AA, SMB package. No circuit modifications are required.

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

A: The P2300SCLRP has 80pF capacitance compared to 56pF in the NP2300SCT3G. This difference is within typical application tolerances for TVS thyristor circuits and does not affect substitution compatibility.

Q: Why does the P2300SCLRP specify different peak pulse current ratings for different pulse widths?

A: Peak pulse current capability varies with pulse width duration. The P2300SCLRP is rated for 400A at 8/20µs and 100A at 10/1000µs. The 10/1000µs rating matches the NP2300SCT3G specification, confirming direct substitution capability.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share identical ECCN and HTSUS classifications. The P2300SCLRP carries RoHS3 compliance, meeting current environmental standards. Both are REACH unaffected.

Q: What is the packaging format difference between these parts?

A: The NP2300SCT3G is supplied in standard packaging. The P2300SCLRP is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Both use the same DO-214AA, SMB component package.
