P2353ACRP Equivalent & Substitute Parts

Part Overview

The P2353ACRP is a 200V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling in a 3-SIP through-hole package. The part is currently obsolete, making identification of active equivalent components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2353ACRP is determined by electrical and mechanical parameter matching within the SIDACtor® TVS thyristor category. The critical parameters for substitution are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current handling (both 8/20µs and 10/1000µs waveforms)
• Hold current specification
• Number of elements (3-element configuration)
• Package type (3-SIP through-hole)
• Capacitance values

The P2353ACLRP meets all these requirements with identical electrical specifications and package configuration, differing only in product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The P2353ACLRP is the direct equivalent for the obsolete P2353ACRP. Both components share identical electrical specifications and mechanical packaging. The P2353ACLRP is currently in active production status and is ROHS3 compliant, making it suitable for new designs and replacement applications where regulatory compliance is required. The primary difference is packaging format: P2353ACRP is supplied in standard packaging, while P2353ACLRP is supplied in tape and reel format for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can P2353ACLRP be used as a direct replacement for P2353ACRP? A: Yes. Both parts have identical electrical specifications, including voltage ratings, peak pulse current ratings, hold current, and capacitance values. The 3-SIP through-hole package is identical, allowing direct PCB substitution.

Q: What is the difference between P2353ACRP and P2353ACLRP? A: The electrical and mechanical specifications are identical. The primary differences are product status (obsolete vs. active) and packaging format (standard vs. tape and reel). P2353ACLRP is ROHS3 compliant while P2353ACRP is not.

Q: Is the tape and reel packaging of P2353ACLRP compatible with through-hole assembly? A: Yes. Tape and reel packaging is a supply format only. The individual components are identical 3-SIP through-hole devices suitable for manual or automated insertion assembly.

Q: Are there any electrical performance differences between these parts? A: No. Both parts have identical breakover voltage (270V), off-state voltage (200V), on-state voltage (8V), peak pulse current (400A at 8/20µs), hold current (150mA), and capacitance specifications.

Q: Which part should be selected for new designs? A: P2353ACLRP should be selected for new designs. It is in active production and meets current RoHS3 compliance requirements.
