P0900SCMCRP Equivalent & Substitute Parts

Part Overview

The P0900SCMCRP 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 designed for transient voltage suppression applications requiring high current handling capability.

The P0900SCMCRP is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this device was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0900SCMCRP is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

• Identical voltage ratings: 75V off-state, 98V breakover, 5V on-state
• Identical current specifications: 400A peak pulse (8/20µs), 100A peak pulse (10/1000µs), 150mA hold current
• Identical capacitance: 70pF
• Identical package: DO-214AA (SMB) surface mount
• Single element configuration
• SIDACtor® series classification

Parts meeting all these parameters are electrically and mechanically interchangeable with the P0900SCMCRP.

Parameter Comparison

Engineering Selection Recommendations

The P0900SCMCLRP is the direct equivalent substitute for the P0900SCMCRP. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters: voltage ratings, current ratings, capacitance, and package configuration.

The primary distinction between these parts is product status and compliance:

• P0900SCMCRP is obsolete and RoHS non-compliant
• P0900SCMCLRP is active and ROHS3 compliant

For new designs and production applications, P0900SCMCLRP is the appropriate selection. The packaging difference (bulk versus tape & reel) reflects standard distribution formats and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can P0900SCMCLRP be used as a direct replacement for P0900SCMCRP?

A: Yes. Both parts are electrically and mechanically identical. They share the same voltage ratings (75V off-state, 98V breakover), current specifications (400A peak pulse at 8/20µs), on-state voltage (5V), hold current (150mA), capacitance (70pF), and DO-214AA package configuration.

Q: What is the difference between P0900SCMCRP and P0900SCMCLRP?

A: The parts are electrically equivalent. P0900SCMCRP is obsolete with RoHS non-compliant status. P0900SCMCLRP is active production with ROHS3 compliance. Packaging differs in distribution format: P0900SCMCRP is supplied in bulk, while P0900SCMCLRP is supplied in tape & reel format.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts use the identical DO-214AA (SMB) surface mount package and are pin-for-pin compatible. PCB layout and assembly processes require no modification.

Q: Why should I use P0900SCMCLRP instead of P0900SCMCRP?

A: P0900SCMCRP is obsolete and no longer in active production. P0900SCMCLRP is the active equivalent with current availability and ROHS3 compliance, making it the appropriate choice for new production and long-term supply chain continuity.

Q: Does the tape & reel packaging of P0900SCMCLRP affect electrical performance?

A: No. Packaging format (bulk versus tape & reel) is a distribution and handling specification only. It does not affect electrical characteristics, performance, or reliability of the component.
