P2300SD Equivalent & Substitute Parts

Part Overview

The P2300SD is a 190V off-state, 1 kA 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 active equivalent parts for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2300SD is determined by electrical and mechanical parameter equivalence. The following criteria establish direct substitutability:

• Voltage ratings (breakover, off-state, and on-state) must be identical
• Peak pulse current ratings (both 8/20µs and 10/1000µs) must match
• Hold current (Ih) must be equivalent
• Capacitance must be identical
• Package and mounting type must be identical (DO-214AA, SMB, surface mount)

The P2300SDLRP meets all these criteria and is therefore a direct electrical and mechanical equivalent. The primary distinction is packaging format (tape & reel versus bulk) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P2300SDLRP is the direct substitute for the P2300SD. Both components are electrically and mechanically identical across all specified parameters. Selection of the P2300SDLRP is justified by the following factors:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance meets current regulatory requirements, whereas the P2300SD is non-compliant
• Tape & reel packaging is standard for automated assembly processes
• Identical electrical performance maintains circuit functionality without redesign

Frequently Asked Questions (FAQ)

Q: Can the P2300SDLRP be used as a direct replacement for the P2300SD in existing designs?

A: Yes. The P2300SDLRP is electrically and mechanically equivalent. All voltage ratings, current ratings, capacitance, and package specifications are identical. No circuit modifications are required.

Q: What is the difference between P2300SD and P2300SDLRP?

A: The primary differences are product status (obsolete versus active), packaging format (bulk versus tape & reel), and RoHS compliance status (non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Does the tape & reel packaging of the P2300SDLRP affect circuit performance?

A: No. Tape & reel packaging is a supply and assembly format only. It does not affect the electrical or mechanical properties of the component itself.

Q: Is the P2300SDLRP suitable for new designs?

A: Yes. The P2300SDLRP is an active product with ROHS3 compliance, making it appropriate for new designs and long-term production.

Q: Are there any other substitutes for the P2300SD?

A: Based on the provided parameters, the P2300SDLRP is the only documented direct equivalent. Other substitutes would require identical electrical and mechanical specifications across all listed parameters.
