P0900SDRP Equivalent & Substitute Parts

Part Overview

The P0900SDRP is a 75V 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 designed for transient voltage suppression applications requiring high current handling capability in a compact form factor. The P0900SDRP is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

The P0900SDLRP qualifies as a direct substitute for the P0900SDRP based on identical electrical and mechanical parameters. Substitution is determined by the following criteria:

• Voltage ratings (off-state, breakover, and on-state) must match exactly
• Peak pulse current ratings (8/20µs and 10/1000µs) must be identical
• Hold current (Ih) must be equivalent
• Capacitance must match
• Package type (DO-214AA, SMB) and mounting configuration must be identical
• Number of elements must be the same

The P0900SDLRP maintains all specified electrical characteristics and physical form factor of the P0900SDRP, with the primary distinction being packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Engineering Selection Recommendations

The P0900SDLRP is the direct functional equivalent of the P0900SDRP for all electrical and mechanical applications. Selection between these parts is determined by non-electrical factors:

• Product Status: The P0900SDLRP is active and supported by Littelfuse Inc., whereas the P0900SDRP is obsolete. For new designs or ongoing production, the P0900SDLRP is the appropriate choice.
• RoHS Compliance: The P0900SDLRP meets ROHS3 compliance requirements, while the P0900SDRP is non-compliant. Applications subject to RoHS regulations require the P0900SDLRP.
• REACH Status: The P0900SDLRP is REACH Affected, indicating compliance with EU chemical regulations.
• Packaging: The P0900SDLRP is supplied in Tape & Reel format, suitable for automated assembly. The P0900SDRP packaging format is not specified but is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the P0900SDLRP replace the P0900SDRP in existing designs?

A: Yes. All electrical parameters, voltage ratings, current ratings, and physical package dimensions are identical. Direct substitution is possible without circuit modification.

Q: What is the difference between P0900SDRP and P0900SDLRP?

A: The parts are electrically and mechanically identical. The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and packaging format (unspecified versus Tape & Reel).

Q: Is the DO-214AA package compatible with existing PCB layouts designed for the P0900SDRP?

A: Yes. Both parts use the DO-214AA (SMB) surface mount package with identical pin configuration and footprint.

Q: Why is the P0900SDRP obsolete?

A: Manufacturer product status is determined by Littelfuse Inc. The P0900SDLRP remains the active equivalent in the SIDACtor® series.

Q: Are there any electrical performance differences between these parts?

A: No. Voltage ratings, current ratings, capacitance, and all specified electrical characteristics are identical.

Q: What certifications apply to the P0900SDLRP?

A: The P0900SDLRP is ROHS3 compliant and REACH Affected. ECCN classification is EAR99.
