P0900SCMC Equivalent & Substitute Parts

Part Overview

The P0900SCMC is a 75V off-state, 400A 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 a Transient Voltage Suppressor and is currently listed as obsolete. Due to its obsolete status, identifying equivalent substitute parts with identical electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0900SCMC is determined by matching the following critical parameters:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current capabilities (both 8/20µs and 10/1000µs pulse profiles)
• Hold current threshold
• Package and mounting type (DO-214AA, SMB surface mount)
• Single-element configuration
• Capacitance specification

The P0900SCMCLRP meets all these criteria with identical electrical performance and mechanical compatibility. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P0900SCMCLRP is a direct functional equivalent to the P0900SCMC with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: The P0900SCMC is obsolete, while the P0900SCMCLRP maintains active product status with confirmed inventory availability (2891 pcs in stock versus 1006 pcs for the obsolete variant).

Compliance Requirements: The P0900SCMCLRP is ROHS3 compliant and REACH unaffected, whereas the P0900SCMC is RoHS non-compliant. For applications subject to environmental regulations or customer compliance mandates, the P0900SCMCLRP is the appropriate selection.

Packaging Format: The P0900SCMC is supplied in standard packaging, while the P0900SCMCLRP is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can the P0900SCMCLRP be used as a direct replacement for the P0900SCMC?

A: Yes. Both parts share identical electrical specifications (voltage ratings, current ratings, and capacitance) and the same DO-214AA SMB package. No circuit modifications are required.

Q: What is the difference between the P0900SCMC and P0900SCMCLRP?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (standard vs. Tape & Reel). Electrical and mechanical performance are identical.

Q: Why should I choose the P0900SCMCLRP over the P0900SCMC?

A: The P0900SCMCLRP is recommended due to active product status, superior availability, ROHS3 compliance for regulatory adherence, and Tape & Reel packaging suitable for automated assembly.

Q: Are there any compatibility concerns when switching from P0900SCMC to P0900SCMCLRP?

A: No compatibility concerns exist. Both parts are pin-compatible, electrically equivalent, and mechanically interchangeable in DO-214AA SMB applications.

Q: What does "Tape & Reel (TR)" packaging mean?

A: Tape & Reel is a standardized format for surface mount components, where parts are wound on a continuous carrier tape and supplied on a reel. This format is optimized for high-speed automated pick-and-place assembly equipment.
